Abstract

The invention discloses a PE (Poly Ethylene) heat shrink film and a preparation method thereof, and relates to the field of packing materials. The PE heat shrink film is prepared from the following raw materials in parts by weight: 40-60 parts of ethylene-ethylene vinyl acetate copolymer, 50-60 parts of poly-3-hydroxybutyrate, 60-70 parts of high density polyethylene, 40-50 parts of linear low density polyethylene, 1-2 parts of antioxygen, 1-3 parts of heat stabilizer, 1-5 parts of fire retardant, 1-3 parts of lubricating agent, 1-3 parts of antiblocking agent and 2-4 parts of plasticizer. Since the raw materials mutually cooperate and act, the prepared PE heat shrink film has various excellent properties, high impact resistance and tear resistance and good transparency and surface glossiness, is easy to degrade and does not pollute environment. The preparation method is simple and easy in operation, and can realize large-scale production.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a PE heat shrinkable film and a preparation method thereof. Background technique [0002] With the continuous development of my country's economy, the demand for heat-shrinkable films in the packaging industry is increasing, and the scope of application is also expanding. Because heat-shrinkable films not only have good comprehensive performance in terms of mechanical properties, packaging, storage, transportation, moisture-proof and appearance, etc. High performance, easy recycling and recycling of raw materials, meet the requirements of environmental protection, and improve the packaging efficiency on the automatic packaging line, reduce the overall packaging cost, and are gradually replacing traditional packaging as the first choice for bulk packaging. [0003] However, the heat-shrinkable film in the prior art has single performance, low strength, easy cracking, poor transpa...
