Production Line 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. 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.
3. 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.
4. Introduction of PA high barrier sheet and production equipment
PA high barrier sheet has good barrier properties, which is better
than PVDC 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 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 PA high-barrier sheet production line is equipped with
precision multi-layer distributors, which has the advantages of uniform layering, adjustable proportions of each layer, and precise
digital control
*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 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.
