Nylon co-extruded vacuum bag by the PA, PE, PP, EVOH and other materials, through the multi-layer co-extruded water blowing blown film made;
Under the water cooling process so that the film has excellent transparency and appearance effects;
By adjusting the thickness of the film can be adjusted forming the depth of drawing and packaging capacity;
According to customer needs to adjust the membrane barrier properties, in the barrier (without EVOH) and high barrier (containing EVOH) between the film can be easily converted;
Special multi-layer inter-layer structure arrangement, for the film to provide a good mechanical properties, processing adaptability, stretching and vacuum effect.
Barrier effect can be adjusted according to the proportion of PA, PE, PP, EVOH.
