Summary of instructions 2019210481025

The utility model discloses a folding environmental protection packaging bag, including a bagbody, a polyurethane base layer, a glass cloth coating, a matte film layer, a starch layer, apolyvinylidene chloride layer, a polytetrafluoroethylene (PTFE) waterproof layer, and a carryinghandle, the said bag body comprising a polyurethane base layer, and the polyurethane base layer iscoated with a glass cloth coating on the outer side of the polyurethane base layer. The utilitymodel has a glass cloth coating on the outside of the polyurethane base layer, which caneffectively improve the fireproof performance of the bag, a starch layer and a polyvinylidenechloride layer, which can improve the degradability of the bag, and a PTFE waterproofing layerconnected to the side of the polyvinylidene chloride layer away firom the starch layer by aninorganic nano-composite binder, which can improve the waterproof performance of the bag, thuseffectively improving the use range of the bag, solving the problem of existing folding bags. Itsolves the problem that the existing folded environmental protection packaging bag does not havethe function of fireproofing and so on, thus limiting its scope ofuse.
