Abstract: A vacuum release device for assisting removal of plastic bags from containers is disclosed. The device is a channel made from non-porous materials. The channel has multiple segments and is capable of being attached to both the sidewall and the bottom wall of a container. As the channel is attached to the walls of the container, an air conduit is formed to provide air conduction in the container. The attachment methods comprises mechanical, chemical, and adhesive. The channel has openings at the container's bottom wall and at the corner between the container's sidewall and bottom wall. The unique structure of the channel protects the openings from being blocked by a plastic liner.
