Kind Code:
A1
Abstract:
A packaging bag or deformed bag (1) made of film of plastic such as polyethylene, comprising a bag proper (2), pattern (3) drawn thereon, opening (4), and string (8), in which the whole or a part of the pattern (3) is composed of two sheets of films made of a material composing the bag or other material of the same kind, the sheets are heat-sealed at the periphery thereof so that a hollow pattern (3) is formed, and the hollow pattern is inflated with air blown thereinto via an opening (5) having a check valve to produce a three-dimensional pattern (3). The pattern (3) of the bag (1) not only is three-dimensional and adds to feeling of mass but also exhibits toy-like effects offered by popular characters and mascot dolls, whereby the bag (1) is made more unique and prettier than before and the production cost for the bag is held almost equal to that for prevailing deformed bags.
