Agricultural mulch-film nutrientNano-encapsulated NPK · nutrient mulch masterbatch · dew-feed release fertilisation
Nano-encapsulation technology wraps the nitrogen, phosphorus and potassium the plant needs, which is then compounded into a PE carrier to make a nutrient mulch masterbatch; once blown into film and laid on the ground, condensation driven by temperature difference and humidity dissolves and releases the nutrients, which drip onto the soil with natural flow — fertilising lastingly, evenly and without excess.

Dew-feed mechanism · a four-step cycle
From nano-encapsulation to drip fertilisation — a naturally driven slow-release cycle.
Nano-encapsulation wraps the NPK
Nano-encapsulation technology is used to wrap the nitrogen, phosphorus and potassium the plant needs, forming controllable-release nutrient microcapsules.
PE carrier makes the nutrient mulch masterbatch
The encapsulated nutrients are added into a PE carrier to make an agricultural nutrient mulch masterbatch; it is then dosed into PE and blown into an agricultural nutrient mulch film.
Condensation from temperature and humidity · dissolution and release
After the film is laid on the farm ground, temperature difference and humidity form water droplets on the film, which dissolve the NPK that has exuded onto the film.
Drips with natural flow · lasting, even, no excess
The nutrients drip onto the soil with natural flow, achieving a lasting, even and non-excessive fertilising effect; suitable for PE mulch film and future degradable mulch film.
Release curve · lasting, even, no excess
R980 dew-feed release is a plateau-type supply; ordinary one-off fertilisation is a peak-and-decay curve (qualitative illustration).

Precautions for use
Keep the strand dry during pelletising — do not pass it through water. (The nutrients are water-soluble; contact with water at the pelletising stage will cause premature loss.)
01Product positioning
Name and structure. The data page is titled 'Agricultural mulch film nutrient agent R980'; the entry structure consists of four sections: Overview, Addition Amount, Application Process, and Usage Precautions. (Data source: product handbook)
Overview (source text as quoted): 'Using nano-encapsulation technology to encapsulate the nitrogen, phosphorus, and potassium required by plants, then adding them to a PE carrier to produce an agricultural nutrient mulch film masterbatch. The agricultural nutrient mulch film masterbatch is added to PE in proportion and blow molded into an agricultural nutrient mulch film. The agricultural nutrient mulch film is laid on the farm ground; due to temperature differences and humidity, water droplets form on the agricultural nutrient mulch film and dissolve the nitrogen, phosphorus, and potassium exuded on the agricultural nutrient mulch film, which drip onto the land with natural fluid flow, achieving a lasting, uniform, and non-excessive fertilization effect.' (Data source: product handbook)
Applicable scope (source text as quoted): 'Mainly suitable for PE mulch film, or future degradable mulch film.' (Data source: product handbook)
Usage key points (source text as quoted): 'Add in the same way as ordinary masterbatch, without changing the original production process.' Usage precautions: 'Try to maintain dry strand pelletizing without passing through water.' (Data source: product handbook)
- Application principle: In the field, the mulch film forms water droplets due to temperature differences and humidity; these dissolve the nitrogen, phosphorus, and potassium exuded from the film surface and drip onto the soil with natural flow—the source states that the goal is a 'lasting, uniform, and non-excessive fertilization effect'.
- Process compatibility: Add in the same way as ordinary masterbatch without changing the original production process; during pelletizing, note to 'try to maintain dry strand pelletizing without passing through water'.
- This grade is a historically listed grade (Discontinued); the data are retained; this page is compiled from historical data as-is.
02Formulation system & mechanism of action
Encapsulation and sustained release: First, nano-encapsulation technology is used to encapsulate the nitrogen, phosphorus, and potassium required by plants; then they are added to a PE carrier to make an agricultural nutrient mulch film masterbatch. (Data source: product handbook)
Release after film formation: The masterbatch is added to PE in proportion and blow molded into mulch film; after the mulch film is laid, water droplets form on its surface due to temperature differences and humidity, dissolve the nitrogen, phosphorus, and potassium exuded from the film surface, and drip onto the land with natural fluid flow. (Data source: product handbook)
Effect target: The source describes it as a 'lasting, uniform, and non-excessive fertilization effect'. (Data source: product handbook)
- Coating — nano-encapsulation of nitrogen, phosphorus, and potassiumNano-encapsulation technology is used to encapsulate the nitrogen, phosphorus, and potassium required by plants.
- Masterbatch formation — added to PE carrierAdded into a PE carrier to produce an agricultural nutrient mulch film masterbatch.
- Field release — water droplet dissolution · natural flow drippingThe mulch film forms water droplets under temperature differences and humidity, which dissolve the nitrogen, phosphorus, and potassium exuded from the film surface and drip onto the land with natural fluid flow, achieving a lasting, uniform, and non-excessive fertilization effect.

04Recommended dosage window
The source gives a range for the dosage of this product:
| Scenario | Dosage | Conditions & notes |
|---|---|---|
| Masterbatch addition ratio | 8-10% | Source text: "[Addition amount] 8-10%"; denominator not specified (transcribed as is, not inferred) |
The source provides only a range and does not specify the denominator; it is presented as transcribed, without inferring a denominator; for values within the range, determine them by small-scale trials based on your own PE raw material and blown film process.
This entry is the only dosage record for this grade in the source; there is no second line and no scenario-specific tiering; this page does not infer a denominator or convert across grades. (Data source: product handbook)
05Applications
Targets and usage:
- PE mulch film
- Agricultural nutrient mulch film: the masterbatch is added in proportion into PE and blown into film, then laid on farm ground for application.
- Degradable mulch film direction
- The source records that the scope of applicability includes the direction of "future degradable mulch film".
- Masterbatch stage
- First, an agricultural nutrient mulch film masterbatch is prepared (NPK nano-coating + PE carrier).
06How it differs from related grades
R980 belongs to the agricultural film functional direction. Among nearby grades in the same brochure, another grade in the agricultural-film-related direction is thermal insulation agent R66—the two have different targets; select by function. Comparison as follows:
| Grade | Data positioning (key points) | Direction | Dosage (as recorded) |
|---|---|---|---|
| R980 | Agricultural mulch film nutrient agent; nano-encapsulated slow-release nitrogen, phosphorus, and potassium | PE mulch film / degradable mulch film direction (nutrient fertilization) | 8-10% (denominator not specified; transcribed as-is) |
| R66 | Internal-addition-type thermal insulation agent for plastic films (data positioning sentence) | Agricultural film thermal insulation direction (different from nutrient function) | Recorded separately in the data (not data for this grade; its values are not listed on this page) |
Reading note: The comparison only indicates each one's data positioning and target application; the two grades have different functions, and their values cannot be substituted for one another. (Data source: product handbook / official product data)

08FAQ
What is R980?
Agricultural mulch film nutrient agent: uses nano-encapsulation technology to encapsulate the nitrogen, phosphorus, and potassium required by plants, add them to a PE carrier to make agricultural nutrient mulch film masterbatch, then add in proportion to PE and blow-mold into mulch film; when the mulch film encounters temperature differences and humidity, water droplets form, dissolve the nitrogen, phosphorus, and potassium exuded on the film surface, and drip naturally into the field; the data describes this as 'persistent, uniform, and non-excessive fertilization effect.' (Data source: product handbook / official product data)
What is the dosage? What is the denominator?
