Material Notes:
The Tritheva TN 2020 resin is a Ethylene-Vinyl Acetate copolymer (EVA) developed to mostly meet the needs of the multi-layer packaging segment produced by coextrusion and/or lamination processes. The structures produced with TN 2020 and PVdC or PA allow radiation treatment and present low rates of water vapor and oxygen permeation, which together ensure a longer shelf life for the food packed in this film. Since it presents an exceptional weldability, this product meets the requirements for automatic or semi-automatic lines of cutting, welding, and/or packaging (with or without vacuum-packed process). Tritheva TN 2020 resin has excellent performance during the extrusion operation, thermal stability, and a low consumption of energy for its processing, rendering to package production a dimensional uniformity and excellent visual properties with high transparency and gloss that enhance the printing and surface finish of the packaging. This product complies with the requirements of Brazilian and corresponding legislation of Mercosul and it is in conformity with FDA Regulations 21 CFR 177.1350, to contact with foodstuff.Applications: Shrinkable packaging for food stuff, such as: cheese, meat, ham, salami and other processed meats. Packaging for frozen products.Resin Properties: Compressed molded plate. Method ASTM D-1928, procedure C. Film obtained on a 50mm blow film line with barrier screw, 25:1 L/D, 1.0mm die gap, 50µm gauge, 2.3:1 BUR.Information provided by Dax Resinas
