| The Tritheva TN 2007 resin is an Ethylene-Vinyl Acetate copolymer (EVA), developed to meet the multi-layer packaging needs where are required high strength, with high toughness, and excellent optical properties. These packages may be produced by coextrusion and/or lamination in combination with many others materials as PVdC, PA, EVOH, etc. This product allows for radiation treatment (crosslinking) and a combination with different materials ensures low water vapor and oxygen transition rates (high barrier). These features are specially important to increase the shelf life of fresh food, and other products. The resin has flexibility at low temperature that enhances applications in frozen food bags, and to provide a low temperature heat seal to itself or many other structure and composition commonly used in flexible packaging applications. The melt properties of this resin allow it to be processed on blow film equipments over a wide range of film thickness and blow-up ratios. 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: High transparency coextruded packaging. Shrinkable packaging for food stuff, such as: cheese, meat, ham, and frozen goods. 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.
