Eltex® Superstress™ CAP508S3是一种高密度聚乙烯共聚物,由欧洲伊诺斯烯烃和聚合物公司使用其专有的载体催化剂和工艺制造,特别是用于注射和压缩成型饮料包装的螺帽。它特别适用于需要优良的抗应力开裂性和增强加工性的应用。由于其纯度高、感官性能优异,非常适合直接接触饮料和敏感食品的包装。典型应用:发泡水和碳酸软饮料包装用瓶盖和瓶盖的注射成型和压缩成型;特别是在减重瓶盖设计中,薄壁包装的注射成型,特别是对食品工业的好处和特点非常好的可加工性,高应力抗裂性超过Llent质量控制感官性能等级,包含一种中等有效的滑动剂,以减少应用和打开盖子时的摩擦。注意:必须避免阳光直射,因为滑脱剂对光敏感,其降解会使饮料产生味道。 Eltex® Superstress™ CAP508S3 is a High Density Polyethylene copolymer manufactured by INEOS Olefins & Polymers Europe using its proprietary supported catalyst & process, particularly intended for the injection and compression moulding of screw caps for the packaging of beverages. It is especially suited for applications requiring excellent stress cracking resistance and enhanced processability. Thanks to high purity and excellent organoleptic properties it is well suited for packaging in direct contact with beverages and sensitive food. Typical applications Injection Moulding and Compression Moulding of Caps & Closures for the packaging of sparkling water and carbonated soft drinks; especially in reduced weight cap designs Injection Moulding of thin wall packaging, especially for the food industry Benefits and Features Very good processability High stress cracking resistance Excellent quality controlled organoleptic properties Grade containing a medium effective Slip Agent to reduce the friction at application and opening of caps. Note : Exposure to direct sunlight has to be avoided as the slip agent is light sensitive and its degradation can give off-taste to the beverage. |
