Claims

[Scope of utility model registration request]

A composite packaging material consisting of a laminate mainly composed of a plurality of synthetic resin film layers, which has an outer film layer in the package and an inner film layer located inside the outer film layer, and the inner film layer includes at least a film layer. A composite packaging material characterized in that a rough surface for facilitating tearing by a contact method or a non-contact method is formed in a part of the width direction continuously in the longitudinal direction of the film.
