Storage bag with a valve and a pressure sensitive adhesive in an inner surface to assist in elimination of air

摘要

A storage bag (10') is disclosed. The bag (10') allows for easy removal of air surrounding the any item in the bag (10'). The bag (10') has two opposing sidewalls (12', 14') which are attached to each other at the side and bottom (20'). At least one of the sidewalls has an outer layer (30') and an inner layer (32') which is substantially unattached to the outer layer except at its peripheral edges. The inner face (38') is covered in protrusions and valleys, the valleys at least partly filled with an adhesive. At least one sidewall has a valve which may be used to extract air from the bag (10'). The bag (10') may also have a closure at the open end (22).
