ABSTRACT:
A method for providing a welded side seam area in a plastic bag or package having interlocking male and female profile sections on plies of plastic sheeting material includes the provision of cut-outs through one of the male and female profile sections and contiguous plastic sheeting material at preselected intervals therealong. The welds, which may be provided by a seal bar or jaws, are provided along lines including or passing through the cut-outs. A thinner and more leak-resistant side seam area between bags or packages is the result.
