In the whole process of production, processing, storage and use, the vacuum bag is gradually fragile due to its natural color and environmental factors, which constitutes its physics and physical performance shrinks and finally loses the value of the product. Therefore, when producing and processing vacuum bags, add WeChat to a chemical thickener that can prevent plastic embrittlement and mildew. Thickeners include antioxidants, light stabilizers, heat stabilizers and antifungal agents according to their full functions. When the vacuum bag touches the polyethylene and vinyl chloride prepolymer in the original material, it is necessary to add a heat stabilizer when adding T. High-pressure polyethylene, polypropylene, polyethylene, polyamide, polyethylene terephthalate, etc. According to different main uses and production and processing regulations, add WeChat to send some anti-restoring agents, sunscreens, etc. Thickeners". According to the organic chemical structure, thickeners can be divided into: zirconium salt. Compound metal material soap (polyether salt of lead, paving, barium, etc.), organic chemical tin, organic chemical antimony, etc. After touching the food category Manufacturers of custom-made vacuum bags, this kind of metal material is easy to transfer to the human food category, the extreme is lead, cadmium thickeners, which are very awkward to the body.
