Material Notes:
The Tritheva TN 8093 resin is a fractional MI copolymer of Ethylene-Vinyl Acetate (EVA), developed to meet the multi-layer and blending film applications 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. The resin has flexibility at low temperature that enhances applications in frozen food bags. Additionally, this resin is designed 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. Tritheva TN 8093 can be use as base polymer for the manufacture of film for greenhouses and both large and small tunnels, with excellent thermal effect at low thicknesses. More detailed information about agricultural film applications and light stabilization recommended, please contact Petroquímica Triunfo representative. 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: Food packaging (meat, cheese), coextruded heat seal layer in food packaging. High clarity film. Base polymer for agricultural film (greenhouse). Stretch hood film.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
