英国帝国化学公司研制出一种填充塑料新型包装材料,称为Kartothene,准备将它作为纸和纸板的代用品。Kartothene是一种由60%聚丙烯和40%滑石粉组成的混合物。它的主要优点是,除可通过热加工成型工艺来压制成各种形状外,还可像普通包装材料那样印刷和折叠。这种材料比纸或纸板要结实得多,同时它的防潮性能极好。目前所用的塑料涂布纸板,多用来包装冰淇淋,食用油脂,动物精饲料和化妆品等等。而今后这些物品的包装完全可用新型包装材料所代替。 Imperial Chemical Company has developed a new type of plastic filled packaging material, called Kartothene, ready to use it as a paper and cardboard substitutes. Kartothene is a mixture of 60% polypropylene and 40% talc. Its main advantage is that it can be printed and folded in the same way as ordinary packaging materials except that it can be pressed into various shapes by the hot forming process. This material is much stronger than paper or cardboard, and at the same time it has excellent moisture resistance. Currently used plastic coated cardboard, used to pack ice cream, edible fats, animal feed and cosmetics and so on. In the future the packaging of these items can be completely replaced with new packaging materials.
