principle

Ultraviolet absorber can absorb ultraviolet rays in light, convert high-energy ultraviolet rays into mature energy and emit them to the environment, thus avoiding the generation of chemical free radicals induced by ultraviolet rays and protecting the contents of PET packaging. The highest wavelength of blocking is divided into three kinds of anti-ultraviolet agents: 360 nm, 370 nm and 390 nm.

applied
