Ⅱ. PVDC seven layer sheet and extrusion machine introduction
1. PVDC high barrier sheet has high barrier properties and chemical resistance. Using the PVDC seven layer sheet extrusion machine, customers can make PVDC three-layer sheet, PVDC five-layer sheet or PVDC seven-layer sheet. The raw materials used are usually PVDC, PS, PP, PVC, PE and HIPS. It is usually used for food packaging such as yogurt, jam, etc. It has a good fresh-keeping function.
2. Gwell PVDC seven layer sheet and extrusion machine
Our PVDC high barrier sheet extrusion line adopts the co-extrusion technology of multiple extruders to produce multi-layer co-extruded composite PA high barrier sheet, such as ABA, ABCBA, ABCDCBA and other multi-layer structures, which are widely used in thermoforming and common food packaging,etc.
Our PVDC high-barrier sheet extrusion machine is equipped with precision multi-layer distributors, which has the advantages of uniform layering, adjustable proportions of each layer, and precise digital control.
*Gwell independently writes an electronic control operating system. Touch screen operation and PLC control make the production line with a high degree of automation, which helps save raw material and labor costs;
Our PA high-barrier sheet production equipment has a compact structure and superior performance. The screw and barrel are optimized. The whole machine has the advantages of good plasticizing ability, stable extrusion, high output and long life.
