ABSTRACT:
The present invention relates to thermoplastic bag structures which are characterized by having a pair of carrying handles which are formed integrally with the bag walls, and extend upwardly from the open mouth portion of the bag. The configuration of the individual bag handles is such that there is reduced tendency for that portion of the handle which is in the user's palm, when such bags are loaded and carried, to curl into a small cross sectional area, commonly known as roping. Additionally, the individual bags are constructed so that when the bags are loaded and being carried by the user, the stress points around the bag mouth are distributed to areas which are less likely to rupture and tear as a result of stress concentration.
