Plastic film recycling lines can treat greenhouse film, mulch film and banana film, etc. The whole plastic film recycling process includes shredding, water rinsing, friction washing, dring by washing system; compacting, plasticization, pelletizing and drying by the pelletizing system. PLC intelligent system realized high automatic, the plastic film recycling line just needs 3-4 man to operate. With over 20 years of experience in recycling, WANROOETECH not only mastered the key technology but also improved machine designs to address specific product features. WANROOETECH offers plastic film recycling line that is high output and low energy consumption.

Why do we need plastic film recycling?

A very important and interesting source of waste in film recycling is represented in agricultural films. The growing interest in agricultural film recycling is made evident by the attention drawn from many agricultural nations and regions. Very specific regulations are being enforced, and legislative action is being taken, towards the creation of a closed-loop cycle in the use of agricultural film, requiring the presence of a recycling step. Agricultural film available for collection may be divided into families:

Greenhouse film: 80÷150 mµ thick, low contamination but significant degradation by atmospheric agents and by the agricultural cycle;

Mulching film: 8÷20 mµ thick, high quality, low degradation, but very thin with a high degree of contamination;

Stretch wrap film: 12÷25 mµ thick, high quality, but very thin with a high degree of contamination;

Banana Film: 10÷15 mµ thick, high quality, but very thin with medium/high contamination;

Non woven PP film: 10÷15 mµ thick, thin material with a significant degree of contamination, difficult to wash and dry;

Irrigation pipes: 200 mµ thick, internal contamination present in the material;

Tunnel film: 30÷40 mµ thick, high quality, low degradation, but the high degree of contamination.

Plastic Film Recycling Line Final Product:

According to the customer’s needs and requirements, Wanrooetech can design plastic film washing lines suitable to treat the different agricultural films, often blended with each other or mixed with post-consumer and/or post-commercial film.
In addition, based on the customer’s requests, we can also design plastic film washing lines expressly dedicated to the most difficult families of plastic film and tailored to the type of waste to be treated. Wanrooetech has already realized around the world plastic film washing lines are capable of treating even the thinnest and most contaminated types of agricultural film.

Plastic Film Recycling Line Process
The entire line is controlled from a central electrical panel, with conveyors linking each process stage.

Plastic Shredder Machine: Long plastic film pieces tend to tangle and wrap around conveyors and rotary equipment. The first step uses a shredder to cut the film into pieces approximately 25–125 mm. We recommend a double single-shaft shredder for this application.

Wet Plastic Crusher: A wet granulator further reduces the film to 10–20 mm flakes. Water is continuously injected into the cutting chamber, which pre-cleans the material and prevents overheating.

Friction Washer: This high-speed washing unit operates at nearly 1,000 RPM. The plastic flakes rub against each other to remove stubborn contamination. Paper and cardboard labels are broken down into fibers and washed away. A second friction washer can be added for heavily soiled material.

Sink-Float Separation Tank: Water separates materials by density. PP and PE films float, while heavier contaminants—dirt, sand, glass, metals, and denser plastics—sink. A bottom screw conveyor removes the settled waste. This stage also provides additional surface cleaning.

Centrifugal Dewatering Machine: The first drying stage uses centrifugal force to remove most surface water before thermal drying. This reduces the energy load on downstream thermal dryers and lowers overall operating costs.

Screw Press Dewatering Machine (Optional): A screw press squeezes water out mechanically under high pressure. This unit can replace both the centrifugal dewatering machine and the thermal dryer in some configurations.

Thermal Dryer + Cyclone Separator: Clean flakes are conveyed into stainless steel tubes where they mix with heated air to remove residual moisture. A cyclone separator at the outlet cools the material with ambient air and removes fines and dust before storage.

Product Silo: Stores the clean, dry flakes before pelletizing.

Plastic Pelletizing Machine: The final stage converts clean film into uniform plastic pellets using a water-ring pelletizing system. You can choose between a standard plastic film pelletizing line or a film squeezing pelletizing machine for higher-moisture feedstock.
