Abstract
A packaging container having an enhanced sealing performance includes a packaging material, an outside strip and a strip tape. The opposite side edges of the packaging material are overlapped with each other so that the outermost layer and the innermost layer of the packaging material face each other. The outside strip is interposed between the outermost layer and the innermost layer and is fused and joined with these layers so that a longitudinal sealing portion is formed. The outside strip has an outside layer and an inside layer. The strip tape is placed on the inner surface of the packaging container along the sealing portion, and is joined thereto by heat fusion. The innermost layer of the packaging material and the outside layer of the outside strip are made of a non-olefin flavor-retaining resin, and the outermost layer of the packaging material and the inside layer of the outside strip are made of a polyolefin resin. Since portions to be joined at the longitudinal sealing portion are both polyolefin, an enhanced sealing performance can be obtained.
