Abstract
A multi-ply, re-sealable label intended for retail use to provide extended text and graphics for consumer information. The label construction includes multiple plies of flexible printed materials using bonding agents and release coatings which allow for numerous openings and re-closures. The label incorporates a consumer-friendly peel-tab for easy opening and re-closure, and materials with a natural "memory" to facilitate re-closure and re-sealability without the use of a tacky adhesive.
Claims17
A method for making a peel-back resealable multi-ply label, the multi-ply label having a hinged top ply overlaying a bottom ply for automatic reclosure of the label, the method comprising the steps of:
- (a) die-cutting a notch in a bottom ply having an upper side and an underside;
- (b) removing waste material from the die-cut notch;
- (c) bonding an underside of a flexible, resilient top ply at a first edge to the upper side of the notched bottom ply with permanent adhesive to form a spring hinge, the spring hinge allowing opening of the top ply to expose the upper side of the bottom ply, the spring hinge also providing for automatic reclosure of the top ply over the bottom ply;
- (d) cutting the bonded bottom ply and top ply to form a final shape of the label, the top ply having a peel tab extending outwardly from a second edge of the top ply opposite the first edge and a peel tab area overlying the notch in the bottom ply.
A method for making a peel-back resealable multi-ply label, the multi-ply label having a hinged top ply overlaying a bottom ply for automatic reclosure of the label, the method comprising the steps of:
- (a) forming a multi-layer bottom ply having an upper side and an underside;
- (b) forming a multi-layer top ply including a flexible, resilient film having an upper side and an underside by performing the steps of:
- (i) applying a permanent, pressure-sensitive adhesive layer to the underside of the flexible film except for on a peel tab area of the film;
- and
- (ii) applying a detackifying layer to the permanent, pressure-sensitive adhesive layer applied to the underside of the top ply except for on at least a hinge portion along a first edge of the flexible film, leaving the permanent, pressure-sensitive adhesive exposed in the hinge portion along the first edge;
- (c) forming a spring hinge by permanently adhering the underside of the top ply to the upper side of the bottom ply with the adhesive left exposed on the hinge portion along the first edge of the underside of the top ply, the spring hinge allowing opening of the top ply to expose the upper side of the bottom ply, the spring hinge also providing for automatic reclosure of the top ply over the bottom ply.
