Abstract:
1. A flexible packaging structure for use in a container for products, comprising: a flexible wrapper comprising a laminate constructed from an outer structure adhesively laminated to an inner structure, the outer and inner structures being coextensive such that each has a width equal to a width of the wrapper, the outer and inner structures having therebetween a pattern-applied pressure-sensitive adhesive disposed in a predetermined pattern and a pattern-applied permanent laminating adhesive disposed in a predetermined pattern not covering the predetermined pattern of pressure-sensitive adhesive; and an opening and reclose feature formed in the laminate, and comprising an outer flap portion formed by an outer score line through the outer structure, and an inner flap portion formed by an inner score line though the inner structure, the inner score line being displaced from the outer score line so as to form therebetween a marginal region of the outer flap portion that extends beyond an edge of the inner flap portion, the inner score line creating an opening into the container when the flap portions are peeled back, the outer score line penetrating though the thickness of the outer structure but not though the inner structure, and the inner score line penetrating though the thickness of the inner structure but not though the outer structure; the pattern-applied permanent adhesive being confined to areas of the laminate outside the marginal region defined between the outer and inner score lines, and the pattern-applied pressure-sensitive adhesive being present in the marginal region, such that the pressure-sensitive adhesive serves for attaching and re-attaching the marginal region of the outer flap portion to an underlying surface of the inner structure.
