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...

Abstract

The invention relates to the technical field of packaging films and particularly relates to a packaging film with high biomass content and a production process therefor. The packaging film is prepared from raw materials, i.e., a biomass raw material, a petroleum raw material and additive color masterbatch, wherein the biomass raw material is prepared from the ingredients in percentage by mass: 30% to 60% of straight-lock very low density polyethylene made from plants, 5% to 30% of low-density polyethylene and 5% to 30% of high-density polyethylene, the petroleum raw material is straight-lock very low density polyethylene extracted from petroleum, the mass percent of the petroleum raw material is 10% to 20%, and the mass percent of the additive color masterbatch is 5% to 10%. Compared with the prior art, the packaging film with high biomass content and the production process therefor have the advantages that the environmental pollution is little, the packaging film is very environmentally friendly, the problem that the traditional packaging films prepared from petroleum raw materials affect environments is solved, the production process is simple, the material performance is stable, the production cost is low, and the industrial feasibility is high.

Description

[technical field] [0001] The invention relates to the technical field of packaging films, in particular to a packaging film with high biomass content and a production process thereof. [Background technique] [0002] The packaging bag made of plastic film is light and thin, impermeable, strong, and low in cost. It is a good packaging material and brings great convenience to people's life. , Plastic film products are widely used in various fields, so the amount of packaging film is increasing. However, the existing packaging films have always been made of petroleum-based polyethylene. This type of petroleum-based plastic film is facing the problem of difficulty in degradation. A large amount of plastic film waste has seriously polluted the natural environment on which we depend. environment. Therefore, if the above problems can be solved, it will be of great significance. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentio...
