Embodiment Construction
[0018] The invention provides a new environmental plant-type PE packaging film with high biomass content. The raw materials of the packaging film include biomass raw materials, petroleum-based raw materials, and additive color masterbatches. Low-density polyethylene, low-density polyethylene, high-density polyethylene, the mass percentages are: straight-locked very low-density polyethylene (LLD) 30-60%, low-density polyethylene (LD) 5-30%, high Density polyethylene (HD) 5-30%, petroleum-based raw material is straight-locked very low-density polyethylene (LLD) from petroleum, its mass percentage is 10-20%, the mass percentage of additive color masterbatch (MB) 5-10%. Such as: (1) Straight-locked very low-density polyethylene made from plants 44%, low-density polyethylene 16%, high-density polyethylene 11%, straight-locked very low-density polyethylene from petroleum 20% , additive color masterbatch 9%; (2) 52% straight-locked very low-density polyethylene, 16% low-density poly...
