PROBLEM TO BE SOLVED: To provide a method for unsealing by tearing from a notch or peeling an unsealing tape without deforming or damaging contents. SOLUTION: A tubular packaging material 1G with a backing member which is to be torn off in a constant width using a sheet which is torn in a predetermined direction as a material is obtained. A composite package 3G receiving contents 2 in the obtained gusset tubular packaging material 1G or a flat-bag- type packaging material has the backing FLR torn off when unsealing, thereby providing an opening 1m for removing the contents. Thus, unlike a torn-off width which is likely to vary with a notch as an initial end, capability of being torn off in a constant width is obtained, and the opening which facilitates removal of contents, which is often difficult in a type for peeling off a tear tape, is provided, so that deformation or breakage is hard to occur on the contents even when rectangular contents are removed.
