High barrier packaging material production line
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.
Ⅰ. Introduction of PA high barrier sheet and production equipment
1. 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.
2. Gwell PA high barrier sheet production line
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
*The production line is equipped with our specially designed screw and barrel, with good plasticizing ability, and with advanced production technology, it can effectively eliminate defects such as crystal spots, white spots and black spots.
