Composite membrane

1.PET:Good barrier, but also has air tightness, moisture resistance, heat resistance and cold, rigid, can be folded thousands of times, the ability of weak acid, weak base, and most organic solvents, oil is good. The surface layer for packaging and printing, can be used between -70 °C -150 °C. 2.VMPET:Good barrier, but also has air tightness, moisture resistance, heat resistance and cold, rigid, can be folded thousands of times, the ability of weak acid, weak base, and most organic solvents, oil is good. The surface layer for packaging and printing, can be used between -70 °C -150 °C, with a good decorative and opacity. 3.PE: a non-toxic, odorless, heat sealing, oil is good for all kinds of light packing. 4.BOPP: for high, there are easy to tear resistance, water blocking resistance, and the price is relatively cheap, easy-to-print, non-toxic, tasteless and can be directly with the food, drug exposure.
