The frequent use and universality of plastic packaging bags make us all pay special attention to what components are plastic packaging bags made of? What can and cannot put food? Now let's talk about the composition of plastic bags?

PVDC coating thin plastic packaging bag group: PVDC polyvinylidene chloride resin is often used as a composite or monomer material and co extruded film sheet. PVDC coating film uses polypropylene, polyethylene terephthalate, etc. as the base material. Pure PVDC has high softening temperature.

And it is close to the differentiation temperature, and has poor solubility with common plasticizers, so it is difficult to heat and mold directly. PVDC films used in practice are mostly copolymers of vinylidene chloride and vinyl chloride, as well as films with excellent insulation properties made by copolymerization with methyl acrylate.

Nylon plastic packaging bag: The characteristic of nylon plastic packaging bag is that the insulation does not decrease with the increase of humidity. The nylon plastic packaging bag used today is a nylon MXD6 polycondensated from m-dimethylamine and adipic acid. It has excellent transparency and puncture resistance, and is often used for food soft packaging with high insulation requirements.

In the process of making customized plastic bags, many factories need to undertake the obligation of environmental maintenance in addition to pursuing economic benefits. As there are certain hazards related to the environment during the manufacturing process of plastic bags, how to reduce waste emissions in the consumption of customized plastic bags is also a concern of current manufacturers. At present, many customized plastic bag manufacturers also innovate from time to time and use more degradable materials as the materials of plastic bags, which can better maintain our environment.

Therefore, in our life, we have a lot of knowledge in many things. In the use of plastic bags, we should also adhere to the economic and environmental protection practices, try to adopt recycling applications, reduce the use of plastic bags, so that we can bring better assurance to our life.
