Development and Simulation of Extrusion Lamination Process with Polyethylene

The types of packages and containers in circulation are extremely wide-ranging: glass bottles, aluminum cans, detergent containers, gift-wraps, food packaging films and so forth. According to the statistics for 2007, total expenditure on packages and containers reached 6.2 trillion yen 1). The theme of this article, extrusion lamination processing, plays an important role in manufacturing paper and plastic products. By laminating polyethylene (PE) onto paper through the extrusion lamination process, water resistant paper products such as milk cartons can be obtained. In addition, by laminating PE onto oriented nylon films (ONy), barrier films or other similar films, various types of plastic products such as food packaging films can be obtained.
