Abstract
Abstract A closure system for a plastic security bag comprises an access opening of the security bag formed by the displaced top edges of the front and rear panels. An adhesive laden carrier film regulates access thereto. The film has an internal line of serration and is affixed to the bag below the top edge of the front panel. A band of temperature-sensitive "hot melt" is supplied therealong. Upon removal of the releasable liner the carrier film is positioned such that the hot melt contacts the rear panel of the bag with the edges of the carrier film aligned with the edges of the rear panel to preclude purchase of the edges. The bag bears ink indicia which deteriorates upon chemical substances being sprayed thereon in an attempt to fracture the adhesive bond. The flush edges of the bag and/or the water-based indicia preclude an undetected, undesirable access to the bag. The bag has scalloped marginal edges which are separable if one attempts to enter the bag at the marginal edges. The attributes of the cellophane carrier film causes cracking if subject to cold temperature. The cellophane also separates at the line of serration if separated from the rear panel. The above characteristics present evidence of an attempted, improper entry to the bag. Proper entry to the bag is accomplished by tearing the carrier film and/or bag proper which is evident to an observer.
