BAG AND METHOD OF MAKING THE SAME

摘要

592230 A plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller (242) and a second cylindrical roller (244), each of which may have a plurality of spaced ridges extending about their peripheries. When the web (202) is directed between the first and second rollers (242, 244), the meshing of the ridges may form ribs into the web.
