概要

論文の詳細を見る
Flexible packages, which consist of thin films and make shapes with contents, attract more attention than rigid packages (which have rigid shapes itself) as minimal environmental impact packaging materials that are suited for recycling-oriented society. The greatest feature of flexible packages is the point that their function can be improved by laminating various plastic films and aluminum foil. I explain plastic films and the laminating technology used for flexible packages. Since most flexible packages are meant for use in direct contact with foods, their safety and sanitary conditions are very important and are subject to control by laws and regulations such as Food Sanitation Law and self-imposed standards of allied hygiene associations. Transparent metallizing high-barrier package materials and automatic opening microwavable retortable pouches are taken up as the latest technology of flexible packages and explained.
