with different plastic material made of a block layer performance difference is very big, reached for oxygen, water, carbon dioxide, odor, such as high separation effect. Vacuum packaging has strong function: oil resistant, moisture proof, resistant to 90 degrees centigrade high temperature cooking, freezing, the quality, freshness and smell. Can be used for vacuum packing, aseptic packing and filling.
with the glass packing, the aluminum foil packing and other plastic packaging, compared to the same barrier effect, co-extrusion film has more cost advantages. Because of its simple process, compared with the dry composite membrane and other composite membrane, the membrane products can reduce the cost of 10 - 20 times.
vacuum bag with scalability in the machining process. After tensile plastic, strength can improve accordingly. Can also be added in the middle, such as nylon and polyethylene plastic materials to make them more beautiful than ordinary plastic packaging, no layered composite strength, good flexibility and excellent heat sealing performance.
