Scientific principles create a protective shield
Ultraviolet rays, a ubiquitous electromagnetic wave in nature, play an important role in the earth's ecosystem, but excessive ultraviolet radiation can cause damage to humans and objects. The key to PEVA film's ability to effectively resist ultraviolet erosion lies in its unique molecular structure and carefully designed additive formula.

The base material of daily PEVA film is copolymerized by polyethylene and vinyl acetate. This copolymer structure gives the film excellent physical and chemical properties. In terms of ultraviolet protection, PEVA film forms an invisible protective shield by introducing specific ultraviolet absorbers or reflectors. These additives can selectively absorb or reflect harmful bands in ultraviolet rays, such as UV-A and UV-B, thereby significantly reducing the ability of ultraviolet rays to penetrate the film and its wrapped items.

Exquisite layout at the molecular level
Further exploration will reveal that the ultraviolet protection mechanism of PEVA film also shows an exquisite layout at the molecular level. Ultraviolet absorbers are usually organic compounds containing conjugated double bonds or aromatic rings, which can absorb ultraviolet rays and convert their energy into harmless heat or fluorescent radiation. The uniform distribution of these absorbers in the PEVA film forms tiny "UV traps" that effectively prevent UV damage to the film.

At the same time, PEVA film may also enhance the protection effect by adding UV reflectors. These reflectors usually have a high refractive index and can reflect UV rays back from the surface of the film, reducing the chance of them entering the interior of the film. This reflection mechanism and absorption mechanism complement each other and together constitute a powerful UV protection system for PEVA film.

Excellent performance in practical applications
The UV protection properties of daily PEVA film are fully reflected. Whether as a food packaging material, a protective layer for household items, or a protective cover for clothing and textiles, PEVA film can effectively block the damage of UV rays. In outdoor environments, it can help extend the service life of items and prevent fading and aging caused by UV exposure. At the same time, PEVA film also has good transparency and flexibility, which does not affect the appearance and use experience of the items. The environmental friendliness of PEVA film is also one of the important reasons why it is favored. It does not contain chlorine, does not produce hydrogen chloride gas that is harmful to the human body, and is environmentally friendly. At the same time, PEVA film is also recyclable, which helps reduce the generation of plastic waste.
