| 备注说明 | TN2020 is an Ethylene-Vinyl Acetate (EVA) copolymer, developed to meet the needs of the segment of multi-layer packages produced by coextrusion and/or lamination processes. Multilayer structures with TN2020 can be irradiated to improve physical proprieties, such as adhesion between layers, puncture resistance and hot sealing. 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). It has excellent performance during extrusion operation, thermal stability, and a low consumption of energy during its processing. It allows production of packages with dimensional uniformity and excellent visual properties. High transparency and gloss enhance the printing and surface finish of the packages. Additives AntioxidantApplication:Shrinkable coextruded films for food packaging, such as: cheese, meat, ham, salami and other processed meats.Packaging for frozen products. |
