High light-barrier PET shrink film is an upgraded product of milky white/black and white shrink film. This product adopts a three-layer co-extrusion biaxial stretching production process, which can achieve more excellent light blocking performance. Compared with traditional shrink film, its advantages are as follows:

1. Compared with white PET shrink film, high light-barrier PET shrink film has better blocking performance against ultraviolet light and visible light. The light transmittance of white shrink film is ≤0.33%, and the light blocking performance in the wavelength range of 200nm~760nm reaches ≥99.67%, while the light transmittance of high light-barrier PET shrink film is ≤ 0.045%, and the light blocking performance in the wavelength range of 200nm~760nm reaches ≥99.96%. More importantly, high light-barrier shrink film can completely block visible light.

2. For end-user applications, the high light-blocking shrink film performance can ｒｅｐｌａｃｅ the bottle body barrier performance. After using the high light-barrier shrink film sleeve label, the amount of barrier agent added to the original white bottle can be reduced, the product cost can be reduced, and the bottle yield can be increased.
