Does the self-standing zipper bag tell you will distinguish between these two common vacuum bags?
Polyester vacuum bag
Manufacture of self-supporting zipper bags Polyester vacuum bags are made of polyethylene terephthalate as the material, made of extruded sheets, and then made of biaxially stretched vacuum bag material. Self-standing zipper bag manufacturers introduce it is a colorless, bright, shiny vacuum bag, excellent mechanical properties, rigidity, hardness and toughness, puncture resistance, collision resistance, high temperature and low temperature, chemical resistance, oil resistance, airtight It is one of the commonly used barrier composite vacuum bag substrates. However, the price of polyester vacuum bags is relatively high, and the thickness is usually 12 μm. The outer layer materials used for cooking and packaging are commonly used for better printability.
Nylon vacuum bag
Self-standing zipper bag manufacturers introduction Nylon vacuum bag is a very tough vacuum bag, good transparency, and has a good luster, tensile strength, high tensile strength, but also has good heat resistance, cold resistance, oil resistance Excellent resistance to organic solvents, abrasion resistance, puncture resistance, soft contrast, good oxygen barrier, but poor barrier to water vapor, greater moisture absorption, moisture permeability, poor heat sealability, Suitable for packaging hard objects such as greasy foods, meat products, fried foods, vacuum packaged foods, cooking foods, etc.
Soft plastic packaging all the way warmer
