Soft PE/PP Waste Recycling Technology in the Circular Plastic Economy

Product Portfolio and Technical Advantages

The recycling of soft PE/PP waste generally involves the following key steps:

1. Collection and Pre-Treatment

Waste films and woven bags are collected, and non-plastic contaminants such as metals, PVC, and paper are removed to ensure stability and efficiency in subsequent processing.

2. Shredding and Washing

The plastic materials are shredded into smaller pieces and washed to remove oils, dust, and other impurities, improving the quality of the recycled material.

3. Drying

Cleaned plastic pieces are dried to eliminate excess moisture, preparing them for the melting and pelletizing process.

4. Pelletizing

Dried plastics are fed into a pelletizer, where they are melted, extruded, cooled, and cut to form uniform, reusable plastic pellets.

5. Screening and Storage

Pellets are screened to remove undersized or defective particles, and the qualified recycled pellets are stored under suitable conditions for downstream manufacturing use.

Applications of Recycled Pellets

Recycled PE/PP pellets can be applied across multiple industries and product types, including:

• Film Products: such as garbage bags, agricultural covering films, and packaging films.
• Injection-Molded Products:including storage containers, pallets, and household items.
• Woven Products:such as plastic woven bags, ropes, and industrial fabrics.

These applications reduce dependence on virgin plastics, lower production costs, and enable effective resource recycling.

Common Types of Recyclable Soft PE/PP Waste

Soft PE/PP waste suitable for recycling typically includes:

Packaging Films

• Food packaging films (e.g., frozen food bags, snack packaging)
• Industrial packaging films (e.g., stretch films, bubble wrap)
• Agricultural covering films (e.g., greenhouse films, ground covers)

Plastic Bags

• Supermarket shopping bags and courier bags
• Garbage bags and waste sorting bags

Soft Woven and Bag Materials

• PE/PP woven bags (e.g., feed bags, fertilizer bags, industrial material bags)
• Plastic ropes or composite film materials

Industrial Waste and Offcuts

• Production scrap from bag or film manufacturing
• Rejected or defective plastic sheets and products

After cleaning, drying, and pelletizing, these materials become high-quality recycled pellets suitable for films, injection-molded products, agricultural coverings, or woven products. Professional recycling systems effectively remove contaminants, enhance material purity, and increase the value of recycled plastics, promoting circular resource use.
