Plastic Film Recycling Line

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.

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 (film washing and pelletizing line):
The entire plastic film recycling line is controlled via a central electric control panel and cabinet. Each piece of equipment is connected using conveyors.


Plastic Shredder Machine: As long pieces of the plastic film easily tangle (imagine saran wrap) and clog conveyors and rotary-based machines, the first step is to cut the plastic film into smaller pieces using a plastic shredder machine. The resulting plastic pieces from the plastic shredder are around 1-5 inches. We recommend that you choose a double single shaft shredder machine.


Wet Plastic Crusher: The plastic crusher cuts the plastic film into even smaller pieces approximately 10-20mm in size. With water constantly injected into the cutting chamber, our wet granulation process also “pre-treats” and partially cleans the plastic film before moving on to the next machine.


Friction Washer: A high-power washing machine, our cold water friction washers spins at nearly 1,000 rotations per minute. As the PP / PE films enter the friction washer, the plastic film rubs against each other at high speeds getting rid of hard-to-remove contamination. At the same time, any paper and cardboard is broken down into fibers and removed. While one friction washer is standard, various washing plants have requested a secondary friction washer to ensure thorough cleanliness.


Sink Float Separation Tank: Using water as a medium, materials that float are separated from materials that sink. In the case of plastic film recycling, PP and PE films will float while heavier contamination such as dirt, sand, glass, metals, and other plastics will sink. A screw conveyor at the bottom of the sink float separation tank removes the contamination. While separation is one aspect of this apparatus, a secondary function is to further clean the plastic film.


Centrifugal Dewatering Machine: The first step in the drying process, our centrifugal dewatering machine uses centrifugal force to remove a large portion of water within the plastic film before moving forward onto the thermal dryers. As thermal dryers use heat to dehydrate water, it requires more energy consumption during operation. Hence, the use of the dewatering machine is beneficial in savings for long-run operations costs.


Screw Press Dewatering Machine: An optional piece of equipment, the screw-press dewatering machine is a more advanced version of the standard dewatering machine. Instead of using centrifugal force to remove water from the plastic film, the screw press squeezes the water out via high pressure. This machine can actually take the place of both the dewatering machine and thermal dryers.


Thermal Dryer + Cyclone Separator: The clean plastic film is vacuumed out of the dewatering machine and into the thermal dryer system where it’ll travel down a series of stainless steel tubes mixing with hot air. The remaining moisture is dehydrated in this process which ends with a cyclone separator. The cyclone separator allows the plastic film to mix with a fresh stream of cold air which prepares it for storage in the product silo. The cyclone separator is also effective in removing fines and such dust.


Product Silo: A storage tank for the clean, dry pieces of plastic film.


Plastic Pelletizing Machine: The final step in plastic film recycling and maybe the most important, the clean film needs to be processed into plastic pellets before it can be used in production. To do so, we offer a specialized plastic film water ring pelletizer system that produces beautiful round plastic pellets. You can choose plastic film pelletizing line or plastic film squeezing pelletizing machine.
