Transparent Pouches with Improved UV Blocking

The flexible materials that are often used for food packages incorporate aluminum foil and metal deposition films to block ultraviolet (UV) rays. However, this means the contents cannot be seen. Transparent films help to reassure consumers by making the interior visible. They also reduce costs and resource consumption during the production process.

The Toyo Ink Group has been working to improve the laminating adhesives that bind plastic films together as well as the coatings that help to prevent UV degradation. The Group has developed a UV coating that cuts ultraviolet rays (200 to 380 nm) by 95% or more. These and other advances are making it possible to preserve food for longer without compromising safety.
