5 Steps to Building Your Own Plastic Film Recycling ...

There are many things to consider when you're building your own plastic film recycling washing line, such as choosing the right plastic film washing lines including shredder, washer and dryer, determining the most suitable cleaning agents, and creating a floor plan. This 5-step guide will help you navigate the process and determine exactly what you need.

1. Determine the types of plastic film that you will be processing and recycling 



Some common types of plastic film include high-density polyethylene (HDPE), polyethylene (PE), polypropylene (PP), , and polyethylene terephthalate (PET). No matter what types of films, wraps, bags or packagings you will be processing, it is important to determine the dirty level of the plastic film and how you would like it to be processed.


Let's take agricultural films as an example. Agricultural films are more contaminated. Recycling agricultural films is a complex process. The films are often delivered in bales and are a mixture of various polymers that must be separated. Additionally, the used films are typically damp or wet and heavily contaminated with substances such as soil, stones, and metals. It can be difficult to assess the level of contamination due to the film being transported in bale form. Organic matter that adheres to the film after silage or harvesting is often already decomposed, further hindering the recycling process. Therefore, you will need a customized plastic film washing line which could include more friction washers or floating tanks.


Upon the customer requirements GENIUS specialist team provides a flexible customized plastic recycling system for each customer starting from sorting units, feeding units,  to degassing units , number or type of filters, storage and packing systems.Moreover, due to the various materials to recycle, GENIUS often helps customers with the unique screw design requirements and pelletizing units. Also, the force side feeding recycling machines are equipped with such as dual piston filters and auto self-cleaning filters upon customer's request. Recently most of the customers prefer die face cutting pelletizing units to achieve more unique pellets for further manufacturing. Plant size has also become another consideration for many customers, the company has already received many customers' appreciation with the custom-size machine manufacturing for various sizes of plants. 





2. Choose the right equipment for your film recycling washing line



Some key pieces of equipment that you will need include a shredder, a wash tank, a drying system, and a granulator or pelletizer. You may also need additional equipment such as a pre-washer or a friction washer.



  • Crusher or Shredder
  • This is a machine that breaks down the film into smaller pieces so it can be washed more easily. They could be a single shaft plastic shredder or twin shaft plastic shredder for different demands.





  • Floating/Wash tank
  • This is where the washing process takes place, and it should have enough capacity to accommodate all of your incoming material. Floating tanks can be used to separate different types of plastics based on their density. This process relies on the sink-float principle, where denser plastics sink to the bottom of the tank while lighter plastics float to the surface. By using this method, it is possible to separate plastics based on their weight and density.





  • Drying system
  • There are many different options available when it comes to film drying systems. Washed films typically retain about 30% moisture. High humidity will negatively impact the efficiency and production of the pelletizing process. Using a plastic squeeze dryer is essential to remove moisture from washed film, reduce the volume of recycled materials, and improve the quality of the final plastic pellets.





  • Friction washer
  • Friction washer is a type of machine that uses friction to remove contaminants from plastic film surfaces. They often consist of a cylindrical drum with an inner drum or impeller, which creates a scrubbing action when it comes into contact with the plastic films, wraps or bags being cleaned.





  • Granulator or Pelletizer
  • Finally, you'll need a granulator or pelletizer. This machine will turn your washed film into pellets or granules that can be used in manufacturing processes like packaging or recycling programs.

3. Determine the layout of your washing line



Consider the size and shape of your facility, as well as the flow of material through the line. The layout of the washing line is an important factor, as it will affect the flow of material through the line and the efficiency of the process. A well-designed layout will minimize the distance that the material needs to travel, which can help to reduce energy consumption and improve overall efficiency.


When selecting equipment for a plastic film washing line and plant, it is important to consider whether you can purchase all of the necessary equipment from the same supplier. There are several advantages to buying all of the equipment from the same supplier :



  • Simplicity:
  • Purchasing all of the equipment from the same supplier simplifies the procurement process, as you only have to deal with one vendor rather than multiple. This can save time and effort, allowing you to focus on other aspects of your business.

  • Compatibility:
  • Buying all of the equipment from the same supplier ensures that the various components are compatible with one another, which can improve the overall efficiency of the washing line.

  • Service and support:
  • A single supplier can provide a more comprehensive service and support package, as they are familiar with all of the equipment in your washing line. This can be especially useful if you encounter any issues or need technical support.

  • Cost savings:
  • Buying all of the equipment from the same supplier may also result in cost savings, as you may be able to negotiate bulk discounts or other favorable terms.



4. Install the recycling washing equipment



Once you have chosen the equipment, the next step is to install it. This will involve setting up the various pieces of equipment, connecting them to the necessary utilities, and ensuring that they are properly calibrated and functioning correctly.



5. Test and optimize your washing line



To optimize a plastic film washing line, you can start by running small batches of material through the line to make necessary adjustments and fine-tune the process. It is also important to monitor and record key performance indicators, conduct experiments to test different variables, use simulation software, and consult with your equipment manufacturers. By following these steps, you can identify areas for improvement and make changes to the process as needed to ensure that the line is running efficiently and producing high-quality washed material.





It seems like a lot of work to build your own plastic film washing line or plant. But once you have it with effective and high-quality systems, you should see consistent improvements in the quality of your washed films, allowing you to increase production and generate greater profits.

    1. Debaler Machine ' As PET bottles (with caps & labels) often come in bales, compacted bundles tied together with metal wires, the first stage is to get the material into a 'free flowing' stream. The 'debaler' breaks apart the bales allowing the plastic bottles within to drop onto the belt conveyor that moves the bottles onto the next step. Learn more about our debaler machine.
    2. Trommel Separator ' A large, slow rotating machine used to remove small pieces of contamination. At the core of the trommel separator is a large mesh screen tunnel that rotates between 6-10 rotations per minute. The holes on this tunnel are small enough so the PET bottles will not fall through, however, large enough so small particles of contamination will. Learn more about our trommel separator.

    1. Wet Granulator / Crusher ' The bottles are cut into 'flakes', or small pieces, via our wet granulator. Simply put, a granulator uses an open rotor mounted with heavy-duty knives that spin at high speeds. As the PET bottles enter the granulator's cutting chamber, these rotating knives come into contact with stationary knives cutting the bottles into small pieces. A screen with small holes between 12-18mm in diameter is used to control the size of the flakes; That is, the PET plastic will continue to be cut within the chamber until it is small enough to fall through the holes on this screen. All the while, water is sprayed into the cutting chamber partially washing the bottles while acting as a lubricate to reduce friction of the knives and plastic. Learn more about our wet granulator
    2. Label Separator ' The stream of plastic leaving the granulator is composed of PET flakes, paper and PP/PE/PVC film from the labels, and PP/PE rigid plastics from the bottle caps. This mixed stream is now ready to be sorted. The first step is the label separator where a column of pressured air blows away the lighter paper and plastic film into a separate collection tank. Learn more about our label separator.
    3. Sink / Float Separation Tank ' A large tank of water used to separate materials that sink from those that float. This is the final separation equipment in our PET bottle washing line that effectively removes the left over plastic films from labels and PP/PE bottles caps. As both the labels and bottle caps float in water, the sinking PET flakes can easily be removed to be further processed in the next piece of equipment. Learn more about our sink float separation tank.
    4. Hot Washer For PET Flakes ' Similar to a washing machine in nature, this stream of PET flakes are washed using boiling hot water which sterilizes and further gets rid of contaminants such as glues (from the labels being glued on), grease/oils, and difficult to remove left-overs (beverage/foods) from the equation. Learn more about our Hot Washer For PET Flakes.
    5. Friction Washer ' A secondary friction washer (cold water) is used to cool and further clean the PET flakes in a scrubbing manner. Learn more about our friction washer.

  1. High Speed Dewatering Machine ' The dewatering machine uses centrifugal or 'spinning' force to remove a portion of the water from the PET flakes. It's a cost-effective way to dry the PET flakes before it's thermally dried. Thermal drying consumes much more energy. Learn more about our dewatering machine.
  2. Thermal Dryer + Cyclone Separator ' The partially dried PET flakes can now be completely dried using the thermal dryers. Within the long tubes of the thermal dryers, hot air and the PET flakes are mixed together where the leftover moisture is dehydrated. The final cyclone separator mixes the hot, moist air with a flow of cold air cooling the PET flakes in preparation for storage. The cyclone separator is also the last defence against fines such as dust. Learn more about our thermal dryer.
  3. Product Silo ' A large storage tank for the clean, dry PET flakes.
  4. Pelletizer / Extruder ' As most PET bottle recycling lines are used to produce clean flakes for use directly in producing polyester staple fibre, we leave the pelleizing equipment as an optional piece in our washing line. ASG offers both single-screw and double-screw extruders for this purpose. Learn more about our pelletizing equipment.
