Description

Multi-layer co-extruded sheet production line is an advanced plastic processing equipment, which uses multi-layer co-extruded technology to extrude and compound a variety of plastic materials with different properties into one or more layers of composite sheets. This production line has the advantages of high efficiency, high quality and low cost, and is widely used in many fields such as building materials, commercial packaging, daily necessities and so on.

Working principle

In the multilayer co-extruded sheet production line, it is first necessary to place different types of plastic particles into their respective extruders. Through the action of heat and pressure, these plastic materials are extruded and formed into a single layer of plastic sheets. These single-layer plastic sheets are then fed into a multi-layer co-extruded melt ejector, where they are melted and combined under high temperature and pressure to form a multi-layer composite sheet. Finally, after cooling, traction, cutting and other processes, the multilayer composite sheet is made to the required length and size.

Application field

The multilayer composite sheet produced by the multilayer co-extruded sheet production line has a variety of excellent properties, such as high strength, temperature resistance, good corrosion resistance, can be filled, reinforced, toughened, stiffened, flame retardant, modified and so on. 

Building materials: Multi-layer composite sheets can be used to make ground materials, waterproof coils, etc., with waterproof, moisture-proof, wear-resistant characteristics.

Commercial packaging: In the field of food packaging, multi-layer composite sheets have high temperature resistance, chemical corrosion resistance and other characteristics, suitable for the production of various food packaging materials. In addition, it can also be used to make gift bags, advertising fans, file bags and other commercial packaging products.

Daily necessities: Multi-layer composite sheets can also be used to make garbage bags, lampshades, mouse pads and other daily necessities, with waterproof, moisture-proof, tensile resistance and other characteristics.
