Plastic Film Recycling Line

Plastic film recycling line is mainly used to process all kinds of waste plastic films, plastic bags, woven bags and so on. The output is 500-2000kg/h. This article will go over the various plastic recycling machines and their prices, as well as the steps of plastic recycling.
plastic pelletizing line

Plastic film recycling line is converting PP PE waste plastic into pelletized plastic. The process involves cutting the plastic scrap into pieces and heating them until they melt. The melted plastic is then passed through a die and pelletized into cylindrical pellets. These pellets can be reused as raw materials in manufacturing plants, thus reducing raw material costs.

What is plastic film recycling line?

The whole plastic recycling granulating line includes crushing, cleaning, and pelletizing waste plastics. The plastic waste recycling equipment mainly includes plastic crushing machine, rinsing tank, vertical type dewatering machine, plastic granulator, cooling tank, and pellet cutting device.

 The plastic recycle equipment of the plastic film recycling line can be flexibly configured according to the raw materials and needs of customers. If you have any needs or questions about plastic film recycling equipment, you can contact us at any time, and a professional will patiently answer your questions.

How plastic film washing line works?

The main process of plastic film washing line production is: plastic sorting → crushing → cleaning → rinsing → drying → granulating → drawing → cutting → packaging

  1. Automatic loading according to customer requirements.
  2. The plastic waste is conveyed to the crusher through the conveyor, and the plastic waste is initially crushed into smaller-sized plastic strips.
  3. Feeding the crushed plastic strips into the friction washer for cleaning.
  4. Entering the dewatering machine to dry the plastic pieces.
  5. The dried plastic pieces are then passed through a pelletizing system that melts the wet plastic into a paste, and the plastic pelletizer will produce hot long strips, which are then cooled in a cold water tank.
  6. Through the plastic granule cutter, the long strips are uniformly made into plastic pellets of uniform size. Finally, these recycled pellets will be stored in a storage bin.

Advantages of plastic recycling granulating line

  • The main advantage of pelletizing is the reduction of plastic waste and the conversion of plastic waste into a clean raw material that can be used in manufacturing processes.
  • Plastic recycling granulating line enables plastics manufacturers to reduce their environmental impact by reducing waste and reusing materials, fulfilling their green initiatives.
  • In addition, plastic recycling granulating line facilitates the storage, transportation, and handling of plastic pellets.

Raw materials & finished products of PE PP plastic film recycling line

The main source of PE PP plastic film recycling line is PP PE waste packaging, such as shopping bags, woven bags, waste plastic from used agricultural films, etc.

Recycled plastic pellets are mainly differentiated into grades according to the different raw materials used and the characteristics of the processed plastic pellets, which are generally divided into one, two and three levels of material.

  • First-grade material is the processing of better quality or unused plastic raw materials, with these as raw materials processed out of the pellet, transparency is better, and its quality can be compared with the new material, so the first-grade material.
  • The second-grade material refers to the raw material that has been used once but has not been exposed to the wind and sun, so its quality is also very good, and the transparency of the processed granules is good, so it is the second-grade material.
  • The third-grade material is the raw material that has been used twice or more, the elasticity of the processed particles, the toughness, and other aspects are not very good.

How to get high-quality recycled plastic pellets?

Several elements of how to get high-quality plastic pellets in plastic pelletizing line.

recycled plastic pellets


If you want to produce high-quality plastic pellets with your plastic film recycling machine, it is essential to choose plastic raw materials that are recycled as few times as possible. The more times the plastic is recycled, the more impurities there will be in the batch.

Material moisture content

Plastic raw materials with high moisture content should not be directly base granulated. This can lead to a large number of pores on the surface of the final plastic pellets after hot melting, plasticizing, extruding, cooling, and pelletizing.

We recommend that the moisture content of the raw material should not exceed 6%, thus avoiding the creation of porosity in the final plastic pellets.

Plastic granulator screw structure

The design of the plastic granulator screw structure will be directly related to the melting and plasticizing effect during the extrusion and pelletizing process.

The unreasonable screw structure will lead to uneven thermal denaturation of plastic in the plasticizing process, which will eventually lead to a significant color difference in the final pellets and lower chemical and physical properties, thus reducing the quality of plastic products using recycled materials. The material is even worse.

Additional details

If you need to ask more about plastic pellets in relation to plastic pelletizing machine, you can contact the staff of Shuliy Machinery. Our technical team will help you choose the right single-screw extruder or twin-screw extruder for your production, depending on the type of plastic to be pelletized and the hardness of the plastic. We will also provide you with a one-on-one explanation of our production lines.

Related machines of plastic film recycling line

Plastic crushing and washing machine

plastic crusher

Plastic shredder machine also known as plastic shredder is an essential part of plastic recycling. This plastic crusher machine is mainly for recycling plastic and is suitable for crushing and cleaning plastic film.

It is characterized by high efficiency in cleaning plastic fragments directly after plastic crushing. The plastic film shredder is equipped with specially treated rotating knives inside, which can crush soft materials into small pieces in a short time. The plastic crusher blades can be resharpened to improve durability.

Plastic rinsing tank

plastic rinsing tank

The plastic film washing machine effectively removes stains from plastics and is made of stainless steel or iron plates.

Plastic drying machine

vertical type dewatering machine

Plastic drying machines are divided into vertical type and horizontal type.

The vertical type dewatering machine is mainly used for the conveying process of plastic soft material after rinsing, to replace the manual fishing material, and to increase the cleaning and automatic high-speed dewatering function, so as to achieve the remarkable purpose of saving labor and electricity consumption, and at the same time with the automatic conveying device to form an automatic assembly line production.

Horizontal type dewatering machine is suitable for dewatering and air-drying plastic crushed hard materials, high-speed centrifugal dewatering, automatic discharge, dewatering rate of 98% or more, and high degree of automation.

Plastic granulator

Plastic granulator

Plastic granulator is the most essential machine in the plastic recycling granulator machine. Thanks to the unique induction heating, plastic recycling granulator can quickly melt the dry material. The heat can be left in the machine, reducing the initial preheating time and always ensuring energy saving, effectively reducing the cost for the customer. The melt flows out of the main machine outlet and then into the auxiliary machine. Under the extrusion of the auxiliary machine, it is extruded from the die in the headstock.

Cooling tank

Cooling tank

The cooling tank is made of stainless steel, which does not rust or corrode. It is mainly used to cool the soft ribbon material extruded from the plastic granulator to harden it. In addition, there are also iron types, and Shuliy can provide different options according to your needs.

Plastic cutter machine

pellet cutting machine

Plastic cutter machine can be plastic drawing feed cutting granules, the main board set stainless steel plate, effectively preventing plastic granule pollution.
