Food bags of thermoplastic resin

- Mar 29, 2017 -

The food bag has the performance of heat softening, cooling hardening, and no chemical reaction, regardless of heating and cooling repeated how many times, can maintain this performance. Where the thermoplastic resin with its molecular structure are linear. It includes all polymeric resins and partially condensed resins. The thermoplastic resins include polyethylene, polyvinyl chloride, polystyrene, polyamide, polyoxymethylene, polycarbonate, polyphenylene oxide, polysulfone, rubber and the like. The advantages of thermoplastic resin processing is simple, with high mechanical energy. The disadvantage is poor heat resistance and rigidity.
