What are the common 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 in a large amount. 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 directly use. PVDC films used in practice are mostly copolymers of vinylidene chloride (VDC) and vinyl chloride (VC), as well as films with good isolation character 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 biggest feature is that its isolation does not decrease with the rise of humidity. In Europe, MXD6 nylon is widely used as a substitute for PVDC films 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 stretching type, the film types of this material also include biaxial stretching type, aluminum evaporation type, adhesive coating type, etc. There are also heat-resistant products for aseptic packaging in the two-way tensile type. EVOH resin and polyolefin, nylon and other resins co extruded film is mainly used for animal products packaging. 4、 PVDC, which is widely used as packaging materials with high insulation, has been replaced by other packaging materials because of the doubt of environmental pollution caused by HCl in the incineration of its waste. For example, the so-called coating film prepared after 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.

Its food hygiene has also been approved by FDA. The most important feature of the film is that its isolation decreases with the increase of humidity.

traditional packaging materials include: paper, plastic, glass, metal, wood, bamboo and other packaging materials; Some traditional foods can also be packaged with lotus leaves and other natural objects..
