发明名称 Roll of plastic film aprons
摘要 Disposable plastic film aprons are prepared from plastic film strip material folded longitudinally in indefinite lengths and the folded film strip packaged in roll form and perforated to provide a plurality of readily separable aprons. The plastic film strip has a plurality of perforations extending transversely thereof to separate one apron from the next on said strip and defining a curved bottom to each apron. The strip has perforations defining straps positioned on opposite sides of each apron extending longitudinally thereof to provide tie straps operable to be tied around the neck of the user and also has perforations extending from the longitudinal fold to define a neck opening. The material is cut away in the portion providing the tie straps but the material remains in place at the neck opening and is removed only after severing of the apron from the roll.
