technical field [0001] The invention relates to a composite material, in particular to a composite material for PE packaging bottles and a preparation method thereof. Background technique [0002] In recent years, new packaging has gradually increased in China's beverage market. At present, the plastic types used for beverage packaging bottles mainly include PE, PP, PVC, PET, etc. Among them, PE (Chinese name is polyethylene) is the synthetic resin with the largest output in the world, and it is also the plastic packaging material with the largest consumption. Polyethylene products are divided into three types: low density, medium density and high density. Among them, high densitypolyethylene (HDPE) has better hardness, air tightness, mechanical strength and chemical resistance due to its high crystallinity. , so it is widely used in blow molding to make hollow containers such as bottles. Taking advantage of the good heat sealing performance of PE, the packaging bottles m...
