Our Company Manufactures seven-layer or nine-layer high barrier packaging material,which is made in one coextrusion by using eco-friendly materials,as EVOH,PA,PET,PP and PE.It has good barrier property like metal,yet there's no shortcoming like metal which is easily corroded by acid, alkali and sulphur. It has the transparency like glass,yet it overcome the fragile limitations.It has the light property like paper,yet it doesn't easily become damp like paper.Of course,it has all the functions as normal plastic film too.Dry composite vacuum packaging and the seven-layer, nine-layer coextrusion packaging, no doubt, have the similar effect, but the only fly in the ointment is that they are easy to be infiltrated and polluted by salty, spicy, acid, alkali and solvents, which are from the goods inside or the factors outside. It will make the composite glue decompose and cause a variety of quality problems. As composite glue contains benzene and ketone, esters of solvent residual matters which cannot completely volatile ,it will destroy the essence and flavor of your product . More seriously, the residue will do latent harm to people’s health. And the seven-layer, nine-layer  coextrusion high barrier packaging is environmental protection packing and repeated used. What’s more ,waste treatment will not produce any pollution to the environment.
The seven-layer, nine-layer coextrusion high barrier packaging film series, can be used in printing, composite, aluminium, bag making, automatic packaging and hot stretch forming, etc. Because of its superior performance, it is widely used in many areas like food, medicine, machinery, chemical, clothing, civil or military, cosmetics, asepsis packing, liquid packaging, pesticide, the balloon film and so on. We can offer better barrier property and extend the shelf life of your products. Our company takes "quality first, credibility first, service the first" as purpose, leading the future of high barrier packaging in China.
