Vacuum packaging bag in our daily use frequency is very high, many families will use vacuum packaging bag to package food, in order to achieve the purpose of extending the shelf life. The material of vacuum bag directly affects its fresh-keeping performance. Next, we will learn about the material and characteristics of vacuum bag.
Commonly used food grade vacuum packaging materials are as follows:
Polyester vacuum bag
Polyester is a polymer derived from polyols and polyacids. Mainly refers to polyethylene terephthalate (PET), polyester (PET) vacuum bag it is a colorless transparent, gloss vacuum bag, is polyethylene terephthalate as raw material, using extrusion method into thick pieces, and then made of bidirectional stretching vacuum bag material. Excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature, chemical resistance, oil resistance, air tightness and good aroma retention, is one of the commonly used composite vacuum bag base materials of permeability resistance. Commonly used as cooking packaging outer material, good printing performance.
Nylon vacuum bag
Nylon (PA) vacuum bag is a very tough vacuum bag, good transparency, and has good gloss, high tensile strength, tensile strength, but also has good heat resistance, cold resistance, oil resistance and organic solvent resistance, abrasion resistance, durable sex good, and is soft, good resistance of oxygen resistance, suitable for packing rigid objects, Such as greasy food, meat products, fried food, vacuum packed food, cooking food and so on. Based on nylon vacuum bag, nylon composite bag and multi-layer co-extrusion vacuum bag can be derived. Nylon composite bag is mainly composed of PET/PE, PVC/PE, NY/PVDC, PE/PVDC, PP/PVDC. The main difference is that the composite bag is generally composed of base material, laminating agent, barrier material, heat sealing material, printing and protective coating. The main component of multi-layer co-extrusion vacuum bag is nylon, which is composed of PA, EVOH and PE, PP, TIE and other resins, and adopts symmetrical or asymmetric combination structure. Due to the addition of PA and EVOH, the barrier of the multilayer film to oxygen and fragrance, composite peel strength, environmental resistance and preservation period were greatly improved. It has the characteristics of no pollution, high barrier, strong function, low cost, small capacity ratio, high strength, flexible structure and so on. It makes the production process of food packaging materials realize no pollution. Three, PE vacuum bag: polyethylene (POLYETHYLENE, referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. Transparent is lower than nylon, feel stiff, sound more brittle, with excellent gas resistance, oil resistance and incense retention performance. Not suitable for high temperature and cold storage, the price is cheaper than nylon. Generally used for ordinary vacuum bag material without special requirements.
Aluminum foil vacuum bag
Aluminum-plastic composite vacuum packaging bag (PET/AL/PE or PET/NY/AL/PE or PET/NY/AL/CPP), the main component is aluminum foil, opaque, silver white, reflective, with good barrier, heat sealing, optical rotation, high temperature resistance, low temperature resistance, oil resistance, aroma retention; Non-toxic and tasteless; Softness and other characteristics. Suitable for moisture-proof, light-proof and vacuum packing of large precision mechanical equipment, chemical raw materials and pharmaceutical intermediates. More than four layer structure, with good water and oxygen insulation function. Aluminum foil vacuum bags are widely used in food, electronics, chemical and other industries. Because aluminum foil itself is relatively expensive, the cost of vacuum will be relatively high. The above is flat flying packaging summary of the vacuum packaging bag commonly used material and characteristics of the introduction, I believe that after reading many friends in the choice of their own product packaging bag will have a general understanding of it.
