Problems solved by technology

[0004] Due to the limited performance of the plastic film used in the inner packaging of synthetic rubber products, when the existing rubber processing enterprises use synthetic rubber for processing, they need to unpack the synthetic rubber before melting it for use, thus increasing the process operation and economic cost

Embodiment Construction

[0014] The present invention will be specifically described below.

[0015] A transparent, low-melting point PE plastic film, which uses polyethylene and EVA resin modifier as the basic raw material, and adds polymer copolymer and organic catalyst with a total content of 15%, and is produced by blown film technology.

[0016] The polyethylene is low density polyethylene LDPE.

[0017] The organic catalyst is metallocene polyethylene, which improves the blendability of polyethylene (melting point 140°C) and synthetic rubber, plays the role of connecting carrier, and reduces the melting point of polyethylene film (80~105°C).

[0018] The ratio of polymer interpolymer and organic catalyst is 1:1.

[0019] Since the second half of 2011, our company has organized production quality technicians to continuously adjust the product process formula on the basis of the existing mature blown film technology. After thousands of tests and technical public relations, in order to meet the pr...

Abstract

The present invention discloses a transparent and low-melting-point PE (polyethylene) plastic film and belongs to the technical field of plastic films. The plastic film is prepared by taking PE and an EVA (ethylene-vinyl acetate copolymer) resin regulator as basic raw materials; adding a macromolecular copolymer and an organic catalyst and performing blow molding, wherein the addition content sum of the macromolecular copolymer and the organic catalyst is 15%. The prepared PE plastic film is improved in aspects of toughness, transparency, thermal viscosity, heat-seal temperature and low odor, and also has the characteristics of low melting point, high transparency, high toughness and the like. The plastic film is mainly applied to inner package of synthetic rubber products. During synthetic rubber processing of a rubber processing enterprise, synthetic rubber packaged by the plastic film is directly molten without package dismounting, which replaces the fact that synthetic rubber packaged by the traditional plastic film is molten after package dismounting; great improvements are achieved in aspects of process operation and economic costs.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a transparent, low-melting PE plastic film. [0002] Background technique [0003] Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins that are used for packaging and as laminations. Plastic packaging and plastic packaging products are taking an increasing share in the market, and have been widely used in food, medicine, chemical industry and other fields. Commonly used plastic films have different melting points, transparency and elasticity according to their raw materials. different. [0004] Due to the limited performance of the plastic film used in the inner packaging of synthetic rubber products, existing rubber processing enterprises need to unpack the synthetic rubber before melting it for use when processing synthetic rubber, thus increasing the process operation and economic costs.
