What is the agricultural film?
The main component of agricultural film is polyethylene, which is used to cover fields and promote the growth of crops and plays an important role in the agricultural industry.
The Necessity of Agricultural Film Recycling
Agricultural film is widely used in agricultural production. If it is not recycled, it will cause pollution to soil, water, etc. Recycling waste agricultural plastic film into recycled granules can save production costs, and promote environmental protection and sustainable development.

Collecting
Common agricultural films include:
- HDPE: Mulch film, greenhouse film, etc.
- PP: Jute cloth, shade net, etc.
- EVA: Greenhouse Covering Materials, etc.
cutting, washing, and drying
Large dirty agricultural plastic films are cut into pieces by a plastic crusher, and then, they are washed in multiple steps by washing tanks. After the above processes, the horizontal drying machine dewaters plastic fragments for subsequent pelletizing.
pelletizing
Advanced screw melting system efficiently heats and melts plastic films into a melt state and then extrudes them by die heads. After shaping and cooling, dense long plastic strips are cut into plastic pellets by a plastic pellet-making machine. During the agricultural film recycling process, there are some tips:
- Suitable Power Output: the Shuliy plastic Pelletier has a capacity ranging from 180kh/h-450kg/h. Small farms or production businesses can opt for machines with lower power, while large production lines require equipment with higher power.
- Temperature Control: Pay attention to the temperature control. Different types of plastic require different temperatures, usually ranging from 160-250 degrees Celsius.
- Screw Speed and Feed Rate: Adjust screw speed and feed rate to ensure the consistency and quality of granulation. Running the screw at too high or too low a speed may result in uneven material mixing, overloading of the screw, or insufficient feeding.
- Cooling and Pelletizing Process: The cooling tank is specially designed to shape plastics to avoid deformation or sticking. There are two kinds of devices for cooling and pelletizing: Water ring pelletizing and strand pelletizing.
