The technical scheme is as follows: a regenerated disposable shopping bag is prepared from the following components:
70-75 parts by weight of polyester bottle chips
5-8 parts of MLLDPE
20-30 parts by weight of a high-pressure polyethylene resin and
5-10 parts by weight of methacrylic acid dehydrated glyceride.
Preferably, the
70 parts by weight of polyester bottle chips
MLLDPE 5 parts by weight
20 parts by weight of high-pressure polyethylene resin
5 parts of dehydrated glycerol methacrylate.
Preferably, the
Polyester bottle chips 72 parts by weight
MLLDPE 6 parts by weight
25 parts by weight of high-pressure polyethylene resin
7 parts of dehydrated glycerol methacrylate.
