What are the plastic packaging materials

I. plastic packaging bag materials (polyvinylidene chloride) polyvinylidene chloride (PVDC) resin is often used as composite materials or monomer materials and co extruded film sheets, which is the most widely used high insulation packaging materials In the meantime, PVDC coated film is used more than ever PVDC coating film is based on polypropylene (OPP) and polyethylene terephthalate (PET) Because pure PVDC has high softening temperature, close to its differentiation temperature and poor compatibility with common plasticizers, it is difficult to heat and form and difficult to be used directly PVDC films used in practice are mostly copolymers of vinylidene chloride (VDC) and vinyl chloride (VC), as well as films with good insulating properties made by copolymerization with methyl acrylate (MA) 2、 Plastic packaging bag packaging materials nylon packaging materials used to use “nylon 6” directly However, the air tightness of “nylon 6” is not ideal There is a nylon (MXD6) polycondensated from m-dimethylamine and adipic acid. Its air tightness is 10 times higher than that of “nylon 6”. Together, it has excellent transparency and puncture resistance It is mainly used for high insulation packaging film, which is used for food flexible packaging with high insulation requirements Its food hygiene has also been approved by FDA As a film, its greatest feature is that its isolation does not decrease with the rise of humidity In Europe, MXD6 nylon is widely used as a substitute of PVDC film because of its outstanding environmental protection 3、 Plastic packaging bag – plastic packaging bag is the most widely used high insulation material In addition to the non tensile type, the film types of this material also include biaxial tensile type, aluminum evaporation type, adhesive coating type, etc Biaxially stretched products are also heat-resistant products for aseptic packaging EVOH resin and other resins such as polyolefin and nylon are mainly used in animal products packaging 4、 Inorganic oxide coated film is widely used as packaging materials with high insulation. Because its waste will produce HCl during incineration, it will cause environmental pollution. At present, it is a trend to be replaced by other packaging materials For example, the so-called coating film prepared by coating SiOx (silicon oxide) on the films of other substrates has received attention. In addition to the silicon oxide coating, there are also alumina evaporation films Its air tightness is the same as that of silicon oxide coating obtained by the same method Materials include: 1.
