摘要: A plastic bag with flexible sidewalls defining an interior volume for holding contents includes a reinforcing feature to resist puncture and/or rupture of the bag. The reinforcing feature may include reinforcing the portion of the bag proximate the bottom edge with additional or thicker thermoplastic material. In various embodiments, the reinforcing feature may be a multi-layer strip of plastic material attached along a bottom edge of the bag, either internally or externally, to provide additional material resistant to puncture. The reinforcing feature may be adhesively bonded, heat bonded, or cold bonded to the bag sidewalls. In other embodiments, the sheet material used to produce the bag may be made with varying thicknesses. In addition, methods of manufacturing a bag with such reinforcing features in a high speed automated process are disclosed.

摘要: The bag may include first and second sidewalls joined along a first side edge, a second side edge and a bottom edge. The sidewalls may be un-joined along their top edges to form an opening. When the bag is placed in a trash receptacle, the top edges may be folded over the rim of the receptacle. To assist with securing the bag to the receptacle, the bag may include an elongated elastic strap of elastic material attached by a first end to an attachment point proximate the first sidewall and by a second end to an attachment point proximate the second sidewall. The strap length and attachment point locations are selected so that, when the strap is in a relaxed state, the strap may not extend to the side edge. The strap may be stretched commensurate with the side edge when folding the top edges about the receptacle rim.
