TN2020是乙烯-乙酸乙烯酯(EVA)共聚物,主要用于满足共挤和/或层压工艺生产的多层包装段的需要。具有TN2020的多层结构可进行辐照以改善物理特性,如层间粘合性、抗穿刺性和热密封性。由于其具有特殊的可焊性,本产品满足自动或半自动切割、焊接和/或包装线(有或无真空包装工艺)的要求。它在挤出操作中具有优异的性能、热稳定性和低能耗的加工性能,使包装生产具有尺寸均匀性和良好的视觉性能,具有高透明度和光泽,增强了包装的印刷和表面光洁度。 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 Antioxidant Application: Shrinkable coextruded films for food packaging, such as: cheese, meat, ham, salami and other processed meats. Packaging for frozen products. |
