Abstract
An unsealing structure for packing films that are difficult to rip to pack merchandise is disclosed, where the films can be easily ripped by stripping a tag label. A tearing line 2 is formed in the surface of the film 1 of the film package by hot shearing. A cutout 3 communicates with the tearing line 2 to assist in unsealing the film package. A tag label 4 is affixed to the film 1 and covers the tearing line 2 and the cutout 3.
