Summary: | A flexible film package having an adhesive based reclosable fastener having a flexible film substrate forming a plurality of package walls sealed to form an interior cavity for receiving a product; the plurality of walls having at least two opposing flexible walls (22,24); a package mouth, initially sealed, to permit access to the interior cavity; a low tack pressure sensitive adhesive (LTPSA) layer (26,28) disposed on each of an exterior surface of the parallel walls, the LTPSA sized and oriented in positions to oppose one another at a plurality of positions when the package is reclosed to allow progressively decreased size of the interior cavity as product is removed; and wherein a bond strength of the LTPSA to the flexible film substrate is greater than an adhesion between LTPSA areas. The mouth can be formed by a peelable seal or by a defined area of weakness. |
