Antifog bench · mist droplets vs water film
Toggle the film surface: untreated fine mist scatters light; after R800 treatment the condensed water spreads into an ultra-thin film and light passes straight through.
Saw palmetto fatty acid × polyglyceryl cocoamide
The antifogging agent R800, also called an anti-drip or antifog-drop agent, is a functional additive of the internal-additive type for plastics; it is made by reacting saw palmetto fatty acid with polyglyceryl cocoamide through a cold-press granulator.
Hydrophobic inwards · hydrophilic outwards
R800 is a surfactant carrying hydrophilic groups and aligns in an oriented way on the plastic surface (hydrophobic groups inwards, hydrophilic groups outwards), raising the critical wetting tension of the polymer surface and reducing the contact angle between water and the polymer surface.
Ultra-thin water film · large drops run off
Condensed fine droplets quickly spread into an ultra-thin water film, or form large droplets that run down the film — preventing drops from falling and damaging the packaged goods or blocking light transmission.

Packing and storage
01Product positioning
What it is. R800 is an internal-addition-type antifog (anti-drip) additive; the official category field is 'antifog agent', and the English category name is 'Antifog Agent'. The documentation classifies it as 'plastic internal-addition type': the antifog agent is added during polymer processing and acts inside and on the surface of the finished article, rather than applying a coating on the film surface afterward. Its main component is saw palmetto fatty acid and polyglyceryl cocamide polymer—formed by reacting saw palmetto fatty acid with polyglyceryl cocamide and then granulating through a cold-press granulator; its appearance is white or slightly yellow waxy granules. (Data source: product handbook / official product data)
What problem it solves. Transparent plastic films, sheets, or panels, under humid conditions when humidity drops below the dew point, develop fine water droplets on the surface, causing haze and obstructing light transmission. The documentation describes the resulting losses on two levels: on the packaging side—'because fogging makes the contents invisible'; fog droplets can also cause the contents to rot and be damaged; on the agricultural film side—temperature differences inside and outside the greenhouse cause mist droplets on the film surface; excessive mist droplets 'obstruct sunlight transmission, weaken photosynthesis, and affect crop growth'; water droplets also absorb solar heat, affect warming inside the greenhouse, and weaken the inherent sanitizing effect of early-morning ultraviolet light. In use there are two routes: direct addition and antifog masterbatch; for the stated scope, see Section 4. (Data source: product handbook)
Name and wording at each level. The title of this grade's technical data page is verbatim 'Antifog Agent/Anti-drip Agent R800'; the product catalog line is verbatim 'R800: Antifog Agent/Anti-drip Agent'; the official full name is verbatim 'Antifog Agent/Anti-drip Agent R800' (English name Antifog Agent R800); the official website list page title is written as 'Antifog Agent/Anti-drip Agent'. (Data source: product handbook / official product data)
Official fields and series coordinates. The official one-line positioning is 'long-lasting antifog, agricultural film and food packaging'; the mechanism field is 'hydrophilic surface activity'; the application list is food packaging film, agricultural film, polyethylene, polyolefin, polyvinyl chloride; the dosage field is '1%—5% of the final plastic product'; R800 is included in the comprehensive series, and its position on the official product list is No. 11. (Data source: official product data)
What it is not. It is not the masterbatch itself (antifog masterbatch is one downstream use form of this product); it is not a resin or filler; nor is it a surface-coating-type treatment agent. Between it and the M800 masterbatch in the same number segment, the documentation establishes no 'internal use' or mapping relationship; the two belong to different product lines, and this page does not calculate by a correspondence relationship. (Data source: product handbook / official product data)
Documentation boundaries (to be clear first). The documentation for this grade provides no dedicated experimental data table or curve, nor any measured data from inside greenhouses or field trials; the values below are all values recorded in the documentation, not a commitment to the effect on any particular film or any particular greenhouse. (Data source: product handbook / official product data)
- High antifog efficacy, fast action, good durability
- Good thermal stability, not prone to thermal decomposition, and the decomposition products do not cause degradation of the polymer
- Good compatibility with other additives, does not interfere with the functions of other additives
- Does not affect the film's transparency, electrical properties, adhesion, contamination resistance, and other functions
02Formulation system & mechanism of action
Composition and manufacturing. The documentation states verbatim: 'Antifog agent (antifogging agent) R800 is also called anti-drip agent or antifog droplet agent. It is a substance that can prevent the surface of transparent materials from generating fine water droplets and thereby reducing light transmittance. R800 antifog agent belongs to the plastic internal-addition type. It is formed by reacting saw palmetto fatty acid and polyglyceryl cocamide, and then passing through a cold-press granulator.' The main component is 'saw palmetto fatty acid and polyglyceryl cocamide polymer'. (Data source: product handbook / official product data)
First layer of the mechanism: oriented arrangement. The documentation defines this class of additives as 'some surfactants with hydrophilic groups, which can orient at the plastic surface, with hydrophobic groups inward and hydrophilic groups outward, thereby making water readily wet the plastic surface; condensed fine water droplets can rapidly spread to form an extremely thin water layer, or large water droplets run down along the film. This can avoid the haze caused by light scattering of small water droplets and prevent condensed water droplets from sprinkling onto the packaged item and damaging it.' (Data source: product handbook)
Second layer of the mechanism: turning fogging into 'non-fogging'. The documentation adds: 'R800 antifog agent is added during polymer processing and can make condensed small water droplets distribute into a continuous transparent thin layer. The function of R800 antifog agent is to increase the critical wetting tension of the polymer surface and reduce the contact angle between water and the polymer surface.' That is, by increasing the critical wetting tension of the polymer surface and reducing the contact angle between water and the polymer surface, it changes how water spreads on the film surface, without changing the intrinsic light transmission of the film. (Data source: product handbook)
Four effects in one. The documentation states verbatim: 'The performance of R800 antifog agent has four properties: initial antifog performance, durable antifog performance, low-temperature antifog performance, and high-temperature antifog performance.' The official website level condenses this into the 'four effects in one antifog' badge. (Data source: product handbook / official product data)
Two synonymous forms of wording at two levels. The documentation has another sentence describing this product as 'mainly internal-addition type'; this and 'plastic internal-addition type' are two levels of wording with the same orientation, and this page uniformly uses 'internal-addition type'. The documentation provides no quantitative data such as the migration rate of hydrophilic groups, the curve of surface tension over time, or the relationship between film thickness and migration amount; for questions that can only be answered with such data, this page gives only qualitative explanations and does not draft values in its place. (Data source: product handbook)
03Key parameters
The physicochemical properties given on this grade's technical data page are as follows (recorded verbatim):
| Item | Value / description |
|---|---|
| Main component | Saw palmetto fatty acids and polyglyceryl cocoamide polymer |
| Appearance | White or slightly yellow waxy granules |
| Flash point | 280 °C |
| Melting point | 68 °C |
| Density | 0.98 g/mL at 25 °C |
| pH (1% water,100°C) | 6.2-7 |
| Total amine value (mgKOH/g) | ≤ 2 |
| Temperature adaptation range | 100-325 °C |
Reading notes (three items). 1. Same values in different notation are recorded verbatim: the official website layer writes flash point as "280 °C", density as "0.98 g/mL at 25 °C", total amine value as "≤ 2", pH as "6.2 ~ 7.0", and temperature adaptation range as "100 – 325 ℃"; these are the same values as in the data sheet page but in different forms, and this page records them by layer, without unifying them on its own. 2. Form is the process result: "white or slightly yellow waxy pellets" are paired with a "cold-pressing pelletizer"; this product is a pelletized additive after granulation, not a powder and not a liquid mother liquor. 3. Concepts and boundaries: melting point 68℃ is a phase-transition temperature, while the temperature adaptation range 100-325℃ is the processing adaptation interval given in the data; the two are not the same concept; this grade does not provide experimental curves or batch fluctuation ranges, and the table above is intended for grade selection comparison and incoming-material verification. Before mass production, please refer to the technical documents supplied with the goods and small-scale test results. (Data source: product handbook / official product data)
04Recommended dosage window
The dosage of R800 has multiple coexisting statements in the data, with different denominators. To avoid errors from cross-conversion, all are listed here by denominator layer, without making a "choose one" selection.
| Scenario | Dosage | Conditions & notes |
|---|---|---|
| Direct addition | 1%-5% | Plastic systems for extrusion coating/blown film with direct addition; the data states that long-lasting antifog of 1-3 years or more can be achieved (usage statement) |
| Substrate classification | Polyethylene 1-5% · Polyolefin 1-5% · Polyvinyl chloride 2-5% · Polyvinyl acetate 1-5% | Corresponding substrate systems; three sentences coexist on the same page, with consistent ranges |
| Addition content | 1%—5% | Plastic final product; the data entry and the official dosage field have the same value |
| Official website scenario layer | PE 1%-5% · PVC 2%-5% · EVA 1%-5% | Corresponding systems; values from the same source, written in layers |
| Masterbatch route | First make masterbatch at 20% → masterbatch 8-20% | Masterbatch preparation stage / masterbatch addition stage; the two stages have different denominators and cannot be mixed in calculation |
Three points must be made clear. 1. Denominators cannot be converted across layers: "plastic final products" and "a certain substrate system" are two denominators; applying 1%—5% to the masterbatch addition stage, or treating masterbatch 8%-20% as the content in the finished article, will both lead to incorrect calculations. 2. The ranges are data records, not commitments: "long-lasting antifog effect of 1-3 years or more" is the usage statement given in the data; actual duration is related to film structure, formulation combination, humidity inside and outside the greenhouse, crop management, and service conditions. Please rely on actual measurements. 3. Directional clause: none—this grade's data does not provide any thickness-dosage directional clause such as "the thinner the film, the higher/lower the dosage"; this page does not state a direction, nor does it apply directional conclusions from other grades; if adjustment by film thickness is required, rely on this grade's small-scale test data.
The above are values recorded in the data; for actual production, please conduct small-scale tests for confirmation in combination with your own system and process. (Data source: product handbook / official product data)
05Applications
Two main application scenarios. The data states that R800 is suitable for food packaging films and is also used in agricultural films, and "can also be used as food packaging material"; the official application list is itemized as: food packaging film, agricultural film, polyethylene, polyolefin, polyvinyl chloride. (Data source: product handbook / official product data)
- Two main application scenarios
- The data states that R800 is suitable for food packaging films and is also used in agricultural films, and "can also be used as food packaging material"; the official application list is itemized as: food packaging film, agricultural film, polyethylene, polyolefin, polyvinyl chloride. (Data source: product handbook / official product data)
- Substrate coverage
- The substrate systems mentioned in the data's classification are polyethylene, polyolefin, polyvinyl chloride, and polyvinyl acetate; the official website scenario layer lists them separately by three systems—polyethylene (PE), polyvinyl chloride (PVC), and EVA copolymer—PE and PVC have explicit statements in both levels of data, while the EVA system is listed separately at the website layer. (Data source: product handbook / official product data)
- Article form boundary
- The data writes the applicable objects as "transparent plastic films, sheets, or panels": films are the main form, while sheets and panels are transparent article forms mentioned in parallel. (Data source: product handbook)
- Changes perceivable by end users
- On the packaging side, the direct significance of antifog is "being able to see the contents" and reducing spoilage and damage of contents caused by fog droplets; on the agricultural film side, the chain is longer—improved light transmission relates to photosynthesis and crop growth, heat transmission relates to greenhouse warming, and ultraviolet transmission relates to sterilization and pest/disease pressure. (Data source: product handbook)
- Boundaries (2 items)
- 1. Functional direction boundary: R800's direction is antifog and anti-drip, which is a different functional direction from anti-blocking/opening slip and thermal insulation; they are not mutually applicable and are not used as comparison statements for substituting one for another; the product list sentence in the data is a column-parallel wording and does not constitute a supporting relationship. 2. Downstream form boundary: antifog masterbatch is one of R800's downstream use forms, not the category of this product; whether to choose direct addition or the masterbatch route depends on whether the production line has masterbatch preparation conditions and metering precision requirements. (Data source: product handbook / official product data)
Field issues & application examples (as recorded in the source material)
| Field issue | What the source material states |
|---|---|
| What product is R800, and where is it used? | A plastic internal-addition antifog (anti-drip) additive; the official category field is "antifog agent" (Antifog Agent); it is mainly used in food packaging films and agricultural films, covering systems such as polyethylene, polyolefin, and polyvinyl chloride. (Data source: product handbook / official product data) |
| What is the antifog mechanism? | It relies on surfactants with hydrophilic groups orienting at the plastic surface (hydrophobic groups inward, hydrophilic groups outward), increasing the critical wetting tension of the polymer surface and reducing the contact angle, so that condensed fine water droplets spread into an extremely thin water layer or merge into large droplets that run down along the film, avoiding the fogging caused by light scattering from small droplets. (Data source: product handbook) |
| What is the difference between R800 and R800F, and how should they be selected? | The two types are independent grades, not split codes of the same product: R800's main components are saw palmetto fatty acid and polyglyceryl cocamide polymer; its appearance is waxy pellets; its direct addition statement is 1%-5%; R800F's main component is sorbic acid alcohol ester; its appearance is powdery; its direct addition statement is 0.5%-5%; the values cannot be copied from one another. Grade selection is determined by the target system, dosage level, and production-line metering conditions; values should be based on the technical documents supplied with the goods and in-house small-scale tests. (Data source: product handbook / official product data) |
| Which number should be used for dosage? | Take them separately by denominator: direct addition 1%-5%; substrate classification polyethylene 1-5%, polyolefin 1-5%, polyvinyl chloride 2-5%, polyvinyl acetate 1-5%; addition content is 1%—5% of the plastic final product; for the masterbatch route, first make masterbatch at 20%, then add at 8%-20%. Different denominators cannot be converted into each other. (Data source: product handbook / official product data) |
06How it differs from related grades
Under the same category field 'Antifog Agent', the source lists an additional R800F entry. The two grades are not split codes of the same product but two independent models: each has its own name, entry, technical data page, and detail page, and the source does not present them as parent-child codes or substitutes. Therefore, the composition, form, and dosage of the two grades must be read item by item; values must not be copied from one another, and specifications must not be cross-applied. (Data source: product handbook / official product data)
| Dimension | R800 | R800F |
|---|---|---|
| Full name | Antifog agent/anti-drip agent R800 | Antifog agent/anti-drip agent R800F |
| Main components | saw palmetto fatty acid and polyglycerol cocamide polymer | sorbitol ester |
| Appearance | White or slightly yellow waxy granules | White or slightly yellow powder-like |
| Direct addition | 1%-5% | 0.5%-5% |
| Substrate tier | Polyethylene 1-5% · Polyolefin 1-5% · Polyvinyl chloride 2-5% · Polyvinyl acetate 1-5% | Polyethylene 0.5-5% · Polyolefin 0.5-5% · Polyvinyl chloride 1-5% · Polyvinyl acetate 0.5-5% |
| Addition level | 1%—5% of the final plastic product | 0.5%—5% of the final plastic product |

Reading note: This comparison only explains the respective source positioning and applicable objects of each grade; values for each model must not be cross-applied. Identification should be based on the official full name and category field. (Data source: product handbook / official product data)
07Usage & storage
The following points are taken item by item from the source records; items not listed in the source are not inferred or filled in.
Key points for use, storage, and transport (as recorded in the source)
- Feeding and route. Direct addition: add R800 at 1%-5% directly in the extrusion coating/blown film process for LLDPE or LDPE; masterbatch route: use R800 20% plus high-melt-index LLDPE to first make an antifog masterbatch, then add at 8%-20%. (Data source: product handbook)
- Processing window reference. With a temperature adaptation range of 100-325℃ and a melting point of 68℃, together with the statement 'good thermal stability, not prone to thermal decomposition, and the decomposition products do not cause polymer degradation,' this product has source-level thermal stability documentation within conventional polyolefin and polyvinyl chloride processing ranges. (Data source: product handbook / official product data)
- Compatibility with other additives. The source states 'good compatibility with other additives, without hindering the function of other additives,' and explicitly states 'does not affect film functions such as transparency, electrical properties, adhesion, and contamination resistance'; actual compatibility results are subject to measured testing in the factory's own formulations. (Data source: product handbook)
- Packaging and storage. Original source text: '25 kg/packaging bag, PE double-layer bag. Store in a cool, dry place; protect from moisture'; the packaging line on the official website detail page records the same (25 kg/packaging bag · PE double-layer bag; storage conditions: cool, dry place, moisture-proof). After opening, reseal promptly to avoid moisture absorption and caking that could affect metering. (Data source: product handbook / official product data)
- Shelf life. Not listed in the source for this grade, and this page does not fill it in; refer to the technical documents supplied with the shipment and the packaging label. (Data source: product handbook)
- Scale-up recommendation (engineering interpretation, not original source text). First run a lab trial: at the target substrate and film thickness, take one point at each end of the dosage range, record initial and sustained performance, then set the pilot-scale value; record substrate, film structure, processing temperature, and dosage to facilitate reproducibility; calculate the masterbatch route in stages—the 20% preparation ratio and the 8%-20% addition level are two different denominators and must not be mixed in calculation.
08FAQ
What is R800 and where is it used?
It is a plastic internal-addition antifog (anti-drip) additive, with the official category field 'Antifog Agent'; it is mainly used in food packaging films and agricultural films and covers systems such as polyethylene, polyolefins, and polyvinyl chloride. (Data source: product handbook / official product data)
What is the antifog mechanism?
It relies on surfactants with hydrophilic groups orienting at the plastic surface (hydrophobic groups inward, hydrophilic groups outward), increasing the critical wetting tension of the polymer surface and reducing the contact angle, so that condensed fine water droplets spread into an extremely thin water layer or merge into larger droplets that flow down along the film, thereby avoiding fogging caused by light scattering from small droplets. (Data source: product handbook)
What is the difference between R800 and R800F, and how should I choose?
The two grades are independent models, not split codes of the same product: R800's main components are saw palmetto fatty acid and polyglycerol cocamide polymer, its appearance is waxy granules, and its direct addition specification is 1%-5%; R800F's main component is sorbitol ester, its appearance is powder-like, and its direct addition specification is 0.5%-5%; values must not be copied between them. Selection should be determined by the target system, dosage level, and production line metering conditions; values should be based on the technical documents supplied with the shipment and the factory's own lab trials. (Data source: product handbook / official product data)
Which dosage figure should be used?
Use the values separately according to the denominator: direct addition 1%-5%; by substrate tier, polyethylene 1-5%, polyolefin 1-5%, polyvinyl chloride 2-5%, polyvinyl acetate 1-5%; addition level is 1%—5% of the final plastic product; for the masterbatch route, first make a 20% masterbatch, then add at 8%-20%. Different denominators must not be converted into one another. (Data source: product handbook / official product data)
How should 'long-lasting antifog of 1-3 years or more' be understood?
This is the usage specification given in the source, not a commitment for a specific finished product: how long antifog performance lasts depends on film structure, formulation combination, humidity inside and outside the greenhouse and crop management, and use conditions. It is recommended to conduct measured records in the target scenario and then set specifications accordingly. (Data source: product handbook)
How is this product labeled regarding halogens?
The source for this product does not address a halogen content specification, and this page makes no halogen-related claim (halogen-containing, halogen-free, and low-halogen wording are all not applicable to this product). If a project requires halogen-related compliance documents, please request them from the supplier according to the specific item number. (Data source: product handbook / official product data)
What are the packaging specifications and storage requirements?
25 kg/packaging bag, PE double-layer bag; store in a cool, dry place and protect from moisture. Shelf life is not listed in the source; refer to the technical documents supplied with the shipment and the packaging label. (Data source: product handbook / official product data)
AppendixData sources
The data on this page comes from two types of source materials and can be traced item by item:
- The facts on this page come from two traceable sources: the product handbook (technical data pages, catalog lines, and company profile in the comprehensive series materials and additive series materials) and official product data (product entry fields, site dictionary, product list, application domains, and detail page copy).
- Dosages, indicators, and packaging are transcribed verbatim from the original text; where the same value is written differently, it is retained by layer without unified rewriting.
- No numbers, mechanisms, or effect descriptions unsupported by the source materials have been used; source boundaries (no experimental data table, no field data, shelf life not listed) have been truthfully noted in the main text.
- The parameters on this page are strictly isolated from those of the adjacent grade in the same category (R800F); wherever adjacent-grade values are cited, the source model is named at each occurrence.
Not covered by the source material (not written on this page — to be added later)
- The company profile listing sentences in the source contain two places inconsistent with the catalog and technical data pages (in one place, the number does not match this model's name field; in another, this model is placed under a different function column). The main text of this page does not adopt the listing-sentence wording; before publication, alignment with the official wording is recommended.
- On the adjacent grade's source page, a few sentences use this model's name as the subject but give values belonging to the adjacent grade (value system 0.5%-5%)—this is a legacy writing issue on the source page; this page has been written according to this model's page wording and isolates this risk. It is recommended that the official side review it as well.
- Layered wording differences: 'saw palmetto fatty acid' and 'saw palmetto lipid fatty acid' on the detail page coexist; 'polyvinyl acetate' and 'EVA copolymer' on the detail page coexist; differences in layered numerical wording are shown in Section 3—all are transcribed by layer and are not mutually corrected.
- Shelf life and safety data (MSDS-type) are not listed in the available source materials.
- 'Long-lasting antifog of 1-3 years or more' has no description of experimental conditions or test methods.
- For this grade, there is no thickness-dosage direction clause available for verification (the available source materials do not provide content in this direction).
