PET vacuum bags and Nylon vacuum bags

The most cost-effective materials for vacuum bags on the market are PET vacuum bags and nylon vacuum bags.

1. PET vacuum bag is a colorless, transparent, and shiny vacuum bag. It is made of polyethylene terephthalate as raw material by extrusion and biaxial drawing.

Features：Excellent mechanical properties, high rigidity, hardness and toughness, and

Good puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness, fragrance retention and printing performance.

It is one of the commonly used anti-permeability composite vacuum bag substrate.

The general thickness is 12um, commonly used as the outer material of cooking packaging.

2. Nylon vacuum bag is a kind of very tough vacuum bag with good transparency, luster, heat resistance, cold resistance, oil resistance, organic solvent resistance, wear resistance, puncture resistance, oxygen resistance, and high tensile strength.

However, the barrier to water vapor and heat sealing is poor, moisture absorption and moisture permeability is greater. Suitable for packaging rigid items. For example, greasy food, meat products, fried food, steamed food and so on.
