当今包装的成功来自于复合不同的材料而获得最终设计产品之性能。包装材料几乎再也没有用单一材料制成的了。近年来取得的最大成就在于共挤、定向拉伸和一种很少有人知道的熔合技术,这些都是增强塑料的机械操作,通过这些操作,常常使塑料成为可接受的包装材料,而不经过这些处理就不能被接受。有关木质纤维,铝、马口铁和玻璃制品的基本材料的价格在不断上涨。它们从原始材 The success of today’s packaging comes from the combination of different materials to get the final design of the product’s performance. Packaging materials are almost never made from a single material. In recent years, the greatest achievements have been achieved by co-extrusion, oriented stretch and a seldom-known fusion technique that enhances the mechanical handling of plastic, which often makes plastics an acceptable packaging material without passing through These treatments can not be accepted. The prices of basic materials on lignocellulosics, aluminum, tinplate and glass products are on the rise. They are from the original material
