PE LDPE HDPE LLDPE Film Recycling Pelletizing Line
PE LDPE HDPE LLDPE Film Recycling Pelletizing Line
PTCS High-efficiency Packaging Film Recycling Equipment
Perfect recycling equipment that combines crushing, extrusion and pelletizing in the same machine
Feeding unit 1
Feeding unit 2
Belt conveyor unit: The recycled waste can be directly placed on the conveyor belt to facilitate feeding, and the conveyor belt controls the feeding rate with ampere quantification.
Clamping wheel set: It can be matched with a belt conveyor unit to feed the entire roll of film on the rack at the same time.
Cutting compaction system
Equipped with a precise temperature control and cutting system to ensure that the semi-molten plastic can quickly and stably enter the extrusion system for mixing and fusion.
Degassing hole
The double degassing hole design of the extruder can release more ink and water vapour in the recycled material to improve the quality of the final product.
Filter screen change system
The double-column screen changing system has a filter area twice as large as the general pallet screen changing system. This screen changing system can improve filtration efficiency and reduce the number of screen changes. In addition to reducing the number of screen changes, the dual-channel design allows the machine to continue to operate during the screen change process, increasing the overall production capacity of the machine and reducing waste.
Laser screen changer (optional for post consumer ldpe film )
Applications:
PTJ continuous melt filters are suitable for processing all standard polyolefins and polystyrenes with the exception of PVC、PVDC、EVA; they are designed to remove foreign particles such as paper, aluminum, wood, elastomers (rubber, silicone) or high-melting polymer composites from heavily contaminated materials.

Pelletizing unit
The hot die pelletizing system can immediately pelletize the melted plastic material after extrusion. Immediately after cutting the pellets, it enters the water ring for cooling. The particle shape and size are average, conducive to re-production in various extruders and injection molding machines.
The recycled particles of the product can be 100% directly put into the film blowing machine or pipe extruder production line for reuse.
The plastic recycling pelletizing line PTCS manufactured is specially designed to recycle PE (HDPE, LDPE, LLDPE) and PP packaging materials. Except for the clean waste (waste from the production line), the printed surface, the washed waste and the crushed small fragments, all can be recycled by PTCS.
Applicable waste materials include: plastic bag factory waste, food packaging waste, all kinds of plastic bags, shrink film, bale film, agricultural film, PE&PS foam material, disposable tableware, PP wire drawing, woven bag, space bag and The crushed hollow molding and injection products can be used for recycling and pelletizing
The recycled plastic pellets produced by PTCS can be immediately used in the production line for re-production. It is most often used to reproduce products on blown film machines and water pipe extruders.
1. Recycled clean plastic once-waste from plastic production plants
Plastic production plants (blowing factories, bag making factories, and printing factories) generate an average of 5% of the total waste output. Recently, because the prices of petroleum and new materials keep rising, the problem of recycling of waste materials in plastic factories has gradually attracted attention. Using recycled plastic materials to make products again can greatly reduce the cost of purchasing new materials.
Recycling the waste produced by the production line (for example: defective film rolls, cutting ears in the bag making process), the quality of the recycled materials can be up to 98% of the new materials. Many manufacturers currently choose to use primary recycled waste to produce products, and the quality of the products produced is quite close to the products made from new materials. This method can save the cost of using raw materials and increase the market value of the product.
2. Secondary recycling waste-washing waste, plastic particles with trace impurities
In response to the needs of different customer groups, PTCS machines can also be used to recycle waste after washing (waste plastic film, agricultural film, cover film for construction projects...). The heat energy generated by the rotation in the PTCS crushing process can be used to heat the waste material after washing and take away the excess water in the material. In the part of the extruder, double degassing holes can release water and printing ink again. The plastic pellets produced by washing raw materials are mostly used to reproduce plastic films used to make garbage bags, engineering films, covering cloth, and to produce water pipes. The PTCS machine can be additionally equipped with a masterbatch/additive feeder to change the color of the recovered particles. Plastic particles with trace impurities
Blown film production plant
The trimming waste remaining after the film blowing machine is produced (the waste from the vest bag stamping manufacturing process) can effectively recycle the entire roll of plastic film and plastic sheet. High-quality, can make the size of recycled plastic particles almost the same, and can be directly put into the film production line for production.
PP weaving factory
The drawnwork, woven bags, space bags and non-woven fabrics produced by the PP weaving factory, Repro-Flex can be recycled and pelletized, and the recycled materials can also be used 100% in the production line for recycling.
Professional recycling plant
Professional recycling plants buy waste plastic materials everywhere. After washing, these plastic wastes can be made into plastic particles again with PTCS. Recycling plants usually add additional color masterbatch or additives to change the color of the particles and improve the quality.
