ABSTRACT:
A T-shirt type grocery bag having a tear-off coupon provided during manufacture. An endless tube of blown thermoplastic is collapsed and printed, including printing for the coupon indicia. The bag is "W" folded forming side for the to-be-formed bag. The folded tube is heat sealed and cut, forming sealed incremental folded tubes. Cutting operations form a bag bottom and produce paired handles on opposing sides of an opening. The definition of this opening also provides a coupon proximate the bag opening. Preferably, the coupon formed lies between the W-folds and its orientation does not permit interference with a bag dispensing structure, such as tabs and wickets. Other embodiments include coupons for thermoplastic bags lacking paired handles and coupons for bags lacking some of the dispensing structures.
