Abstract

A selectively closeable plastic film bag is formed with front and rear plastic film panels.
The bag includes a bottom and side edges and each of the front and rear panels include a top edge whereat an opening is provided into the bag cavity. An adhesive strip is provided on the inside surface of the front or rear panels extending longitudinally thereacross between the bag side edges. The adhesive strip is placed in a pattern extending at an angle upwardly from each of the side edges to a generally linear portion therebetween. A release liner is provided between the front and rear panels and is located partially over or above the adhesive strip at the side edges and below the linear adhesive strip portion. The adhesive strip portion covered by the release liner is prevented from coming in contact with the other bag panel thereby retaining the bag open. The release liner is detachably attachable to the adhesive strip. For closing the bag, the release liner is pulled out from between the panels causing the adhesive strip to come in contact therewith. The adhesive strip extends uninterrupted from side edge to side edge thereby making the closure leakproof. Pocket panels are attached to the bag thereby forming pockets for selectively receiving items therein. The front and rear panels are provided with weakened material lines extending between the side edges for easily ripping and gaining access to the bag cavity. To prevent fusing of the release liner to the front and rear panels, both the release liner and front and rear panels are cut away at the bag side edges above the adhesive.
The release liner extends above the front and rear panels top edges or into notched areas at the bag side edges whereat it may easily be gripped.
