Plastic foam pelletizing line is mainly used for recycling and pelletizing various waste foam. The waste plastic is crushed into small plastic pellets which can be used twice as packaging materials, insulation materials, etc. The most important equipment of the plastic foam pelletizing line is the plastic foam extruder which will melt and extrude the plastic pellets.
What are EPS foam and EPE material?
Foam EPS is a common plastic material that is made from polystyrene through a special processing process. It is commonly used in packaging materials, construction materials, and various household products. It gets its name from its appearance, which usually takes the form of white foam.
Foam EPS is widely used in construction materials because of its excellent thermal insulation and shock absorption properties. However, the manufacturing process of EPS foam generates a lot of waste gas and wastewater, which causes pollution to the environment. And the service life of foam EPS is relatively short, which is not conducive to environmental protection and sustainable development.
Expandable polyethylene (EPE), commonly known as pearl cotton. EPE consists of many individual bubble holes produced by chemical or physical foaming. EPE pearl cotton foam is light and soft, absorbing impact and dispersing energy under the action of external forces to cushion items. Widely used in high-end furniture, electronic products, pharmaceuticals, and other valuable and fragile items of packaging.
Raw materials and final products of plastic foam pelletizing line
The main source of plastic foam pelletizing line is EPE EPS waste packaging, such as foam fast food boxes, foam packaging boxes, fruit net covers, refrigerator outer packaging foam and other white foam waste.
Through the plastic foam pelletizing line, EPS and EPE foam are granulated and eventually new recycled pellets can be obtained. It can be made into other new products to be put into use, and realize the waste to treasure of foam.
Process flow of expanded polystyrene recycling machine
Option 1: Horizontal EPS foam compactor + Plastic foam extruder
Due to the low density of polystyrene foam, it is not easy to collect. Therefore, horizontal EPS foam compactor is needed for processing, and the compressed EPS foam blocks are easy to transport. This plastic foam extruder includes crusher and granulator. The compressed EPS foam blocks can be shredded and then processed into new plastic pellets.
Option 2: EPS foam melting machine + Plastic foam granulator
If there is no requirement for raw material transportation, you can choose the EPS foam melting machine directly. The EPS EPE foam will be melted first and then granulated using the plastic foam granulator.

EPS foam melting machine
The EPS foam melting machine is specifically designed to reduce the volume of waste-expanded polystyrene foam (EPS) by crushing, hot melting, and extrusion molding. It minimizes the volume occupied by EPS foam products and the melted material can be used to make other plastic products.
Foam compactor
After the plastic foam is compressed by the EPS Polytron recycling compressor, the foam density increases and it is in square shape, which is very convenient for transportation and storage. There are two types of compactors: vertical EPS foam compactors and horizontal EPS foam compactors.
Plastic foam granulator
The plastic foam granulator is one of the most important machines in the plastic foam pelletizing line. It consists of a crusher and a granulator. The granulator can melt and extrude EPE and EPS waste plastics into reusable plastic granules.
Cooling Tank
The cooling tank is used to cool and harden the extruded plastic long strips of the granulator to facilitate the next step of pelletizing.
Plastic pellet cutting machine
Plastic pellet cutting machine can cut plastic long strips into pellets, and the size of the pellets can be adjusted. And the main board is set with stainless steel plate to effectively prevent plastic pellet pollution.
