Problems solved by technology

[0003] The existing sunshade packaging production equipment is complicated, occupies a large area, requires a large investment, and has quick results. At the same time, the film produced is stretched and inflated, and has low mechanical strength, while most of the common PE films have poor compatibility with polymers. , the compatibility with polyolefin is poor, and the components in it are easy to volatilize after being irradiated by ultraviolet light, which affects the service life of PE film, and has high energy consumption and is not environmentally friendly

Abstract

The invention discloses a production technique for an environment-friendly sunshade package, which comprises the following steps: preliminary mixing, preparation of master batch, extrusion and film blowing, printing, dry lamination, modification and cutting. In the production technique, because polyethylene wax is adopted as a lubricating agent, the chemical property is stable, the electric property is good, the flowability of polyethylene can be improved; moreover, because a whitening agent is added to play the role of whitening, a super-white environment-friendly PE (polyethylene) film is produced; because oleic acid phthalein amine is adopted as a modifier, the glossiness and processability of the product can be increased, the friction between the internal friction film and conveying equipment in the process of processing can be reduced, consequently, output is increased, and the operation for the final product is simplified; because the finally produced raw PE film does not have solvent residue, the PE film is more environmentally friendly; and the appearance of the sunshade package produced by adopting the PE film is better.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a production process for environmentally friendly sunshade packaging. Background technique [0002] With the development of science and technology, sunshields are used in all aspects of life, such as in cars, people will still feel extremely uncomfortable due to the stuffy atmosphere in the car, and what's more, it will cause heat stroke. In order to alleviate this state, car sunshades Become an important tool to block the sun's rays to slow down the temperature rise in the car. [0003] The existing sunshade packaging production equipment is complicated, occupies a large area, requires a large investment, and has quick results. At the same time, the film produced is stretched and inflated, and has low mechanical strength, while most of the common PE films have poor compatibility with polymers. , the compatibility with polyolefin is poor, and the components in it are...
