Product Description

Recycled LDPE /LLDPE Pellet for Plastic bag Film/plastic bags/packaging films/ agricultural films

Product Overview:

Our recycled LDPE pellets are specially designed for the production of agricultural greenhouse film and mulch film, made from clean post-consumer and industrial LDPE film waste (including greenhouse film scrap). With strict washing and multi-stage filtration (≥80 mesh), our pellets feature low moisture (≤0.3%), low ash content (≤0.5%), and no PVC/PP/metal impurities, ensuring stable extrusion and film blowing performance.

Suitable for both pure recycled and blended with virgin LDPE formulations, our product delivers excellent tensile elongation (≥70% of virgin LDPE) and oxidation induction time (OIT ≥10 min), meeting the requirements for durable, weather-resistant agricultural films. Available in natural/clear/white grades, we offer flexible packaging (25kg PP bags or 1MT jumbo bags) and reliable supply capacity to support your greenhouse film production needs.

High Quality Natural LDPE Pellets for Blown Film Plasitc Bag Products

Key Features:
Greenhouse Film Grade Formulation
Specially designed for agricultural greenhouse film and mulch film production, with ideal melt flow rate (MFR 0.6–8.0 g/10min) for stable extrusion and film blowing.
High Purity & Low Impurities
Made from clean LDPE film waste, processed with multi-stage filtration (≥80 mesh) to ensure moisture ≤0.3%, ash content ≤0.5%, and no PVC/PP/metal contaminants.
Excellent Mechanical & Weather Resistance
Delivers tensile elongation ≥70% of virgin LDPE and oxidation induction time (OIT) ≥10 min, providing durable, UV-resistant agricultural films with long service life.
Flexible Processing Compatibility
Compatible with both pure recycled and blended formulations (mixed with virgin LDPE), suitable for standard blown film lines to meet different production requirements.
Customizable Appearance & Packaging
Available in natural/clear/white color options, with flexible packaging (25kg PP bags or 1MT jumbo bags) to suit your logistics and storage needs.
Eco-Friendly Recycled Material
Derived from post-consumer and industrial LDPE film scrap, reducing plastic waste and supporting sustainable agricultural packaging solutions.

Product Application Scenarios:
Agricultural Greenhouse Film Production
Our recycled LDPE pellets are the ideal raw material for manufacturing transparent/photodegradable greenhouse films, providing excellent light transmission and weather resistance to protect crops from cold, wind, and pests.

Agricultural Mulch Film Manufacturing
Suitable for producing black/color agricultural mulch films, helping to retain soil moisture, control weeds, and improve soil temperature for higher crop yields.

Blended with Virgin LDPE for High-Performance Films
Can be blended with virgin LDPE resin (30%–70% recycled content) to produce high-end functional agricultural films (UV-resistant, anti-drip, heat-preserving), balancing cost and performance.

Other Agricultural Plastic Films
Also applicable for the production of silage films, fruit protection films, and nursery pot films, extending the service life of agricultural plastic products while reducing production costs.

Industrial Packaging Film (Secondary Use)
Can be used for general-purpose industrial packaging films (e.g., stretch wrap, protective films) when mixed with new materials, offering a cost-effective alternative to pure virgin LDPE.

Applicable Raw Materials:
Clean postonsumer LDPE agricultural greenhouse film scrap
Industrial LDPE film leftover and offcuts
Posindustrial LDPE packaging film waste
Recycled LDPE mulch film waste (washed and sorted)
Mixed LDPE film waste with low impurity content
