翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Perforation ： ウィキペディア英語版 Perforation A perforation is a small hole in a thin material or web. There is usually more than one perforation in an organized fashion, where all of the holes are called a ''perforation''. The process of creating perforations is called perforating, which involves puncturing the workpiece with a tool. Perforations are usually used to allow easy separation of two sections of the material, such as allowing paper to be torn easily along the line. Packaging with perforations in paperboard or plastic film is easy for consumers to open. Other purposes include filtrating fluids, sound deadening, allowing light or fluids to pass through, and to create an aesthetic design. Various applications include plastic films to allow the packages to breathe, medical films, micro perforated plate and sound and vapor barriers. ==Processes== Perforation can be created by pins, needles, die and punch or laser. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perforation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
