PACKAGING TUBE AND WRAPPING AND PACKAGING FOR DRY BATTERY

摘要

PURPOSE:To make it possible to obtain a compact packaging tube and wrapping or packaging for dry battery in an easily automatizable process by joining together a film large in heat shrinkage coefficient and a film small in heat shrinkage coefficient. CONSTITUTION:A packaging tube is formed by joining together a film 1 large in heat shrinkage coefficient and a film 2 small in heat shrinkage coefficient. In this case, the film 2 having a thickness of at least 50mum and difficultly bendable is used. These features of the film 2 makes unnecessary the process of placing a paperboard into the tube and also possible the printing of pictures and letters on the film 2 by gravure. This leads to an easy automation of wrapping or packaging process and the reduction of costs, thus a compact wrapping or packaging being obtained.
