Self-supporting zipper bag manufacturer introduces it as a colorless, bright and lustrous vacuum bag with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, conflict resistance, high temperature and low temperature resistance, chemical resistance, oil resistance and airtightness. It has good properties and good aroma, and is one of the commonly used barrier composite vacuum bag substrates. However, the price of the polyester vacuum bag is relatively high, usually 12 μm in thickness, and is commonly used as the outer layer of the retort package, and the printing property is good.
