EVOH High Barrier Sheet Extrusion Machine Provide Installation And Commissioning

Ⅰ. EVOH High Barrier Sheet Extrusion Machine introduction

1. Introduction of EVOH high barrier sheet and production equipment

The barrier effect of EVOH high-barrier sheet is ten times higher than that of PVDC high-barrier sheet. EVOH sheet production machine can produce EVOH three-layer sheet, PVDC five-layer sheet or PVDC seven-layer sheet. The raw materials used are usually EVOH, PS, PP, PVC, PE and HIPS. It is usually used for food packaging such as dairy products, meat and canned food, as well as packaging for chemicals, electronic components and medicines.

2. Introduction of EVOH high barrier sheet and production equipment

EVOH high barrier sheet has good barrier properties, which is better than EVOH sheet under high temperature condition, but not as good as PVDC sheet under room temperature. With our PA sheet production machine, customers can make three-layer sheet,five-layer sheet or seven-layer sheet. The raw materials used are PA, PS, PP, PVC, PE and HIPS. The product is usually used as food packaging.

Our PA high barrier sheet production line adopts the co-extrusion technology of multiple extruders to produce multi-layer co-extruded composite EVOH high barrier sheet, such as ABA, ABCBA, ABCDCBA and other multi-layer structures, which are widely used in thermoforming and common food packaging,etc.

Plastic film has a certain shielding ability to small molecule gases, liquids and odor molecules. The permeability coefficient is usually used to indicate the size of the plastic barrier.

At present, the commonly used high barrier packaging materials are PVDC, EVOH and PA.

*Inclined roller structure makes machine operation and maintenance more convenient

*Roller is with independent power, linear speed is synchronized with extruder speed to make a closed-loop 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 EVOH 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.
