Abstract: 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.

Abstract: Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.

Abstract: One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.
