The commonly used materials of food grade mylar bags are as follows:
1. Polyester vacuum bag:
Polyester is a general term for polymers obtained by polycondensation of polyols and polybasic acids. Polyester vacuum bag mainly refers to polyethylene terephthalate (PET), polyester (PET) vacuum bag is a colorless transparent and glossy vacuum bag. Polyester vacuum packaging bag is made of polyethylene terephthalate (PET) by extrusion and biaxial drawing. Polyester vacuum packaging bag has excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, good chemical resistance, oil resistance, air tightness and fragrance retention. It is one of the commonly used barrier permeability composite vacuum bag substrates. Polyester vacuum packaging bag is often used as the outer material of cooking packaging, with good printing performance.
2. Nylon vacuum bag:
Nylon (PA) vacuum bag is a very tough vacuum bag, which has good transparency, good luster, high tensile strength and tensile strength. It also has good heat resistance, cold resistance, oil resistance and organic solvent resistance, good wear resistance and puncture resistance, and is relatively soft and oxygen resistant. It is suitable for packing hard goods, such as greasy food, meat products, etc Fried food, vacuum packaging food, cooking food, etc. Nylon (PA) vacuum bag is a very tough vacuum bag with good transparency, good luster, high tensile strength and tensile strength.

Nylon vacuum bag is suitable for packaging hard goods, such as greasy food, meat products, fried food, vacuum packaged food, cooking food, etc. On the basis of nylon vacuum bag, nylon composite bag and multilayer coextrusion vacuum bag with higher performance can be derived.
3.Aluminum foil vacuum bag:
Aluminum plastic composite vacuum packaging bag (pet/al/pe or pet/ny/al/pe or pet/ny/al/cpp), mainly composed of aluminum foil, is an opaque, silver white, anti gloss packaging bag. Aluminum plastic composite vacuum packaging bag has good barrier property, heat sealing property, light shielding property, high temperature resistance, low temperature resistance, oil resistance and fragrance retention; Non toxic and tasteless; It is soft.
Aluminum plastic composite vacuum packaging bag is suitable for moisture-proof, lightproof and vacuum packaging of large precision mechanical equipment, chemical raw materials and pharmaceutical intermediates.
Aluminum plastic composite vacuum packaging bag adopts four layer structure, which has good water and oxygen isolation function. Aluminum foil vacuum bag is widely used in food, electronics, chemical industry and other industries. Because the raw materials of aluminum foil are more expensive, the cost of vacuum will be higher. The above is a detailed introduction of the common materials and characteristics of vacuum packaging bags summarized by ZhongXin Packaging Co., Ltd. I believe many people will have a general understanding when choosing product packaging bags after reading.
