Description

Technical Field

[0002] The existing PE plastic films lack a structure to strengthen them, resulting in serious deficiencies in various performance strengths such as the anti-seepage performance, anti-fatigue strength, anti-puncture performance, strength, and barrier property of the PE plastic films themselves, which affects the practicality of the PE plastic films.

[0003] Chinese Patent No. CN214727121U discloses a PE protective film with a matte texture, including a protective film main body. The protective film main body includes a sandblasted film body, a reinforced protective film body, and a PE base film. The reinforced protective film body is compression-molded on the top of the PE base film, and the sandblasted film body is compression-molded on the top of the reinforced protective film body. The reinforced protective film body is used to form force protection and anti-corrosion protection for the PE base film. The sandblasted film body is used to form a matte texture while protecting the film body from damage. The sandblasted film body includes a matte spraying coating, an adsorption film layer, and an anti-seepage film layer. The adsorption film layer is thermally melted and connected to the top of the anti-seepage film layer. Through the combined design of the sandblasted film body, the reinforced protective film body, and the PE base film, the utility model makes the protective film easy to achieve a matte texture during sandblasting, avoids damage to the inside of the film body caused by sandblasting, and greatly improves the pressure resistance and anti-corrosion performance of the film body.
