A PP film recycle washing line refers to a piece of equipment used to sort, wash, and granulate PP film for PP film recycling. The typical PP film recycle washing lines consist of a crushing machine, floating tank, dryer machine, and granulating machine. However, the lines may consist of different machines depending on the type of film and the desired output.

Here are some types of PP film washing lines:

• Full Automatic PP Film Washing Line

  The full automatic PP film washing line is fully automatic, meaning it has a high level of automation. In the full automatic PP wash lines, the granulating machine is often connected to a full automatic feeding system. Moreover, the lines may include a full automatic water filtering system. Besides, full automatic PP washing lines are equipped with a powerful control panel that allows for more precise operation and monitoring. The control panel may feature programmable logic controllers (PLCs) for higher automatization. Such a feature ensures that the final product meets the highest standards.

• PP Agricultural Film Washing Line

  The agricultural PP film washing lines have special features that can handle specific contaminants found on agricultural plastics, such as soil, organic matter, or plant residues. They may include pre-treatment units for removing large contaminants or integrated drying systems for faster processing. Additionally, the agricultural film washing lines are customizable to accommodate different types and volumes of agricultural films. As a result, the flexibility ensures that they meet the specific processing requirements of various agricultural film recyclers.

• PP Stretch Film Washing Line

  Just like the agricultural washing lines, the stretch film washing lines have specialized sorting, shredding, and washing equipment to handle the specific properties and contaminations of stretch films. More often than not, PP stretch film washing lines are equipped with multi-functional cleaning units, such as friction washers and float-sink separators, to remove different types of contaminants. Moreover, the stretch film lines may include pelletizing units that produce high-quality stretch film granules suitable for manufacturing stretch film products.

• PP Shrink Film Washing Line

  Similar to the stretch washing lines, the shrink washing lines are equipped with advanced washing units to handle specific types of impurities. The distinguishing feature of the shrink washing lines is the kind of separation methods used to remove contaminants. For instance, some shrink washing lines use sink-float separation methods or friction-based cleaning techniques. Additionally, some shrink washing lines may come with optical sorting technologies to achieve higher levels of material purity.

• Mixed Plastic Film Washing Line

  Unlike the separate PP washing lines, the mixed plastic film washing line is designed specifically for processing a combination of plastic films. Generally, the mixed film consists of various polymer types, such as PE, PP, and others. The advantage of the mixed washing line is that it can handle plastic films that are difficult to recycle individually. Furthermore, the mixed film lines offer flexibility to process a wide range of inbound film contaminants.

Specifications and maintenance of PP film recycle washing lines

The specifications of the PP film recycling line may vary depending on the manufacturer's design and the buyer's customized requirements. The film washing line's capacity is one of the critical specifications. It is usually expressed in kilograms per hour. For example, a washing line may have a capacity of 300-500 kg/h, which means that it can process 300-500 kg of film waste in one hour.

The processing steps in a washing line are usually the same, but the machine types and quantities may differ according to the film material and the line's capacity. The critical machine types include the separator, shredder, flotation washer, dryer, and granulator or extruder. For example, a line may have a dry flotation washer, which is a more water-saving method.

Overall dimensions and power requirements are also essential specifications for buyers. The length of the entire washing line may be more than ten meters. The engine's power may vary between 5 and 50 KW for different machines.

Because the recycling washing line processes a lot of plastic waste that may be contaminated, maintaining the washing line is crucial. It mainly involves cleaning and checking the machine parts frequently to avoid the build-up of dirt and to keep them working smoothly. Water is used liberally during the recycling process and is critical to the machine's maintenance needs. It is essential to use enough water during the process to clean the machines, wash the waste, and cool the equipment. Using water is also necessary to reduce energy consumption and prevent plastic from burning inside the machine.

Before the washing line is started, it is vital to inspect all the parts, including the water pipes and the rubbish, to see if there is any part that is damaged or needs to be looked at. To avoid any operational issues, check the motor, transmission-gear, bearings, and seals, and pay special attention to any friction area or link that needs lubrication.

During operation, all safety guards should be in place, waste material should not be put in the hopper other than what the machine processes, and any foreign material should be cleared before starting. Recycling plants are strict about adhering to safety standards, and all staff should be provided with safety gear that includes goggles, gloves, and hard hats.

Scenarios of PP film recycle washing lines

PP film recycle washing lines are useful in different settings.

• Plastic recycling facilities

  Such facilities use the line as part of their process to collect, cleanse, and granulate plastic films for distribution. Here is where bigger capacities come into play since large quantities of films need to be recycled here at a time. It's about saving the planet, and that means going big!

• PP film manufacturers

  Sometimes these manufacturers produce more than the market can consume. They have to recycle the surplus. A small on-site PP film washing line could help them recycle their own scraps right away and reduce storage costs.

• Agricultural sectors

  Agricultural sectors that make use of plastic films, like greenhouses and livestock farms, can benefit from having a PP film recycling washing line nearby. It would save transportation costs as the films can be recycled right at their location.

• Small-scale businesses

  While big washing lines may be too costly for small enterprises to cope with, a small-scale portable washing line would come in handy. These portable lines allow small businesses to process their own plastic waste and earn extra income through recycled materials.

• Developing regions

  In areas where access to advanced recycling technologies is limited, even low-cost or manual PP film recycling solutions can be life-changing. They empower local communities to manage their plastic waste and create value from it.

How to Choose PP Film Recycle Washing Lines
