Abstract
The instant invention relates to a handled thermoplastic bag made of a thermoplastic film comprising a high density polyethylene or a major amount of high density polyethylene and a minor amount of one or more other polymers, e.g., linear low density polyethylene. The handled bag is characterized by a front and rear bag wall, a closed bottom and an open mouth top portion having a pair of laterally spaced handles, said front and rear bag walls, between said handles defining an open bag mouth and is further characterized as comprising a smoother cut-out edge at corner portions of the open bag mouth than provided at said lower mouth edge whereby the smoother cut-out edge of the corner portion reduces the tendency of the thermoplastic film to tear at the corner when subjected to stress. Use of the aforementioned smooth corner cut-out is also beneficial in manufacturing handled bags at commercial manufacturing rates.
