Introduction of Main Machines of PP/PE Film Washing System

The PP/PE film washing line employs a variety of machines that are maximized to play specific roles in the production process, which together ensure the production of high-quality recycled plastic pellets. The following series of primary machines are used for their respective purposes:

Single/twin shaft shredders:

Shredding machine

  • Through the pushing system to forcibly send the materials to the rotor for shredding, the shredder is equipped with a large-capacity hopper and crushing chamber, with efficient shredding capacity, providing large shear force to ensure high grinding output.

Precipitation separator

Pre wash unit

  • Cleaning pool drum for the intense pressure underwater cleaning design, maximum removal of residual impurities, different specific gravity materials to be separated, discharging for the continuous claw drive design, to ensure that the material is uniform and constant at the same time to control the water content.


Pre wash unit

  • Special blade shaft suit for film/woven bag grinding. Cutting the materials to a suitable size makes it easy to convey the next step.

High-speed friction washer

High speed friction washer

  • The friction washer machine has a suitable rotating speed to press the raw material and wash the flakes more cleanly.

Mechanical dryer

Mechanical dryer

  • The material entering the de-watering machine is evenly dispersed after being hit by the blades; the centrifugal force generated by the high-speed rotation can remove the water to the maximum extent.

Thermal dryer

Thermal dryer

  • The hot air drying system controls the moisture content of the finished product to 10%-15%, which is suitable for high-quality Pelletizing requirements.

Film Squeezing machine

 Film Squeezing machine

  • They are mainly used for the semi-plasticizing and cutting of films. The specially-structured screw runs at high pressure to remove moisture. The electromagnetic heater semi-plasticizes the film, extrudes it through the die, and the high-speed rotating cutter head uniformly cuts the pellets.

Together, these form a complete plastic film cleaning and recycling system that converts waste plastic film into reusable, high-quality recycled pellets.



Material Handling Strategies in PP/PE Film Cleaning Systems

Material handling is critical to the PP/PE film cleaning system and significantly impacts overall cleaning efficiency and recovery utilization. The following are tips for optimizing your material handling strategy:

Classify and sort beforehand.

Sort and separate film materials by type, color, and degree of contamination for subsequent cleaning processes. This improves cleaning efficiency and reduces cross-contamination.


For example, crushing or mechanical grinding can make the film material smaller and uniform. This helps to increase handling and facilitates the cleaning process.

Foreign Matter Purpose

Metal guides, sorters, or flotation techniques can reduce the foreign matter in the film material, such as metals, stones, or other metals. Foreign matter is essential to protect the equipment and ensure cleaning quality.

Water washing

Water purification of particles removes residues from pores, such as grease and soluble substances. The water purification utilizes friction, soaking, and rinsing for efficient purification.

Sieving and targeting

A screen or centrifuge separates the cleaned film particles from the cleaning solution. The separation process helps to avoid wasted water in preparation for subsequent processing.

Friction Cleaning:

  • It is achieved mechanically using brushes or other abrasive materials in contact with the film.

Chemical Cleaning Alkaline Cleaning:

  • A robust alkaline solution, such as hydrogen or potassium hydroxide, achieves surface cleaning and coating.

Acid Cleaning:

  • Acidic solutions, such as nitric or nitric acid, remove metal oxides and rust.

Solvent Cleaning:

  • Use organic solvents, such as propanol or acetone, to dissolve isoparaffinic solutions.

Best practices multi-stage cleaning programs, combining different technologies to improve efficiency.

  • Optimize cleaning parameters such as temperature, time, and concentration levels. Maintain cleaning systems regularly to ensure optimal performance.
  • By carefully considering the choice of cleaning technologies, companies can optimize the efficiency of their PP/PE film cleaning systems and maximize recycling.

Features of PE film washing line

The system is designed to handle highly contaminated films with more than 80% contamination. These state-of-the-art systems offer the following features and benefits:

  • Abrasion-resistant design: The washing line is made of a robust and wear-resistant material that can withstand the intense abrasion and corrosion of the processed film.
  • Pre-crushing and pre-cleaning systems: The integrated pre-crushing and pre-cleaning stages effectively remove large contaminants and impurities from the film in preparation for subsequent cleaning.
  • High-speed cleaning system: Equipped with a high-speed cleaning system, the film is thoroughly cleaned using a high-pressure water flow and agitation device to remove stubborn dirt and residues.
  • Underwater forced washing: Underwater forced washing paddles enhance the washing effect, remove micropollutants on the film’s surface, and ensure thorough washing.
