Abstract
The invention relates to a bag closure for a thermoplastic grocery bag. Integral closure tabs are formed in the bag front and rear walls at the bag mouth. After the bag has been loaded, the front wall closure tab is pulled across the bag open mouth towards the rear of the bag. The rear wall closure tab is then pulled in the opposite direction across the bag mouth towards the front of the bag to engage an adhesive zone positioned on the exterior surface of the front wall. The adhesive zone is made up of a low tack, high-shear adhesive and is positioned just below the bag mouth. The adhesive zone resists shear forces generated while the bag is closed but releases easily when the rear closure tab is pulled in a direction normal to the bag wall.
