Light-barrier shrink film sleeves made by Gilbreth from opaque, high-performance, high-yield, lightweight PETG-HY film provide up to 99% UV and visible light-blocking product protection to safeguard light-sensitive packaged products. For maximum light shielding, Gilbreth applies two coats of black ink to the reverse side of the film to offer the protection from visible and UV light, without precipitating any visible change to the crisp bright white base color on the label front. Decorative, promotional and brand-reinforcing color graphics are surface-printed and can be protected with an overprint varnish layer. Strong, lightweight PETG-HY film shrinks up to 76%. The excellent shrink characteristic permits material down-gauging with the potential to reduce material consumption by up to 20%. Phone (800) 630-2413;
