Material Notes:
The Trithene TS 7028 resin is a low-density polyethylene (LDPE) with excellent optical and processability properties that allows for the production of films combining appearance, mechanical strength, and welding along with a uniform thickness. The incorporated additive package confers thermal stability and appropriate coefficient of friction (COF) that are fundamental for achieving high productivity on printing, cutting, welding and bagging lines. This product complies with ASTM standard D1248-IA3 and the requirements of Brazilian and corresponding legislation of Mercosul and it is in conformity with FDA Regulations 21 CFR 177.1520 (c) 2.1, to contact with foodstuff.Applications: Films for automatic or semi-automatic packaging of food products (grains, powder, or farinaceous) such as cereals, sugar, salt, and flours. Structure-laminated technical films with PP, BOPP, polyester and/or aluminum foil for packaging miscellaneous products such as coffee, crackers, etc.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
