摘要:
One or more implementations of a multi-film thermoplastic bag with a conjoined hem channel. For example, the multi-film thermoplastic bag includes a multi-film hem channel. Bonds secure the layers of the hem channel together so as to prevent a drawtape from inverting or bunching an inner layer of the hem channel during cinching. The bonds are thus located in a hem channel of a multi-film thermoplastic bag so as to reduce an amount of mechanical engagement between the films of the multi-film thermoplastic bag and another thermoplastic film such as a drawtape. In one or more implementations, a grab zone of the multi-film thermoplastic bag also includes bonds in the form of contact areas to provide tactile and visual cues of strength in the grab zone.
