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.
