Abstract
A shopping bag of thermoplastic synthetic resin sheeting with lateral weld seams wherein, at the bag opening, the front wall is fashioned with a straight rim, and the rear wall is fashioned to project beyond the front wall with an approximately sinusoidal rim to form a protruding flap. The sinusoidal rim of the rear wall terminates either above or below the rim of the front wall in the lateral weld seams. A process for the production of the shopping bags by sinusoidal cutting apart of a film ply of a tubular sheet involves a series of sequential operation at successive stages or stations.
