Abstract

An improvement is made in a package including a protective film enclosing an article and a tack label coupled to an outer surface of the protective film such that a step of forming a slit in the protective film can be omitted and the need to form a dent at a specific area in the article is eliminated. A protective film includes an overlapping portion in which a first edge portion directly opposing the article and a second edge portion opposing the article via the first edge portion are overlapped with each other, and in a coupling surface between a tack label coupled so as to cover the overlapping portion and a protective film, a non-uniform coupling force distribution is provided in which a second region continuously connected to the second edge portion has a higher coupling force than a first region continuously connected to the first edge portion.
