PROBLEM TO BE SOLVED: To provide a pillow-type package using a high-intensity packaging film, which can prevent a cutter blade from being worn and yet can be cut easily at one time.SOLUTION: A face with no back seal line 1a is set as a front side, and on the front side is provided a weakened line 11 extending from a top seal line 1b toward a bottom seal line 1c. The weakened line is constituted of an aggregation of fine through-holes in inverted V-shapes which penetrate through a base film. The site of the weakened line is lower in intensity than other sites, which allows the weakened line to be tore off by hands. As the weakened line is constituted of the aggregation of the fine through-holes, loads of a large volume of contents are scattered without being intensively applied to the through-holes. This can prevent a package from being broken carelessly although the package is provided with the through-holes that penetrate through the high-intensity base film.SELECTED DRAWING: Figure 1 |
