RECLOSABLE PACKAGING USING A LOW-TACK ADHESIVE FASTENER

摘要

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; a package mouth, initially sealed, to permit access to the interior cavity; a low tack pressure sensitive adhesive (LTPSA) layer 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.

主权项

1. A flexible film package having an adhesive based reclosable fastener, comprising:
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; a package mouth, initially sealed, to permit access to the interior cavity; and a pair of low tack pressure sensitive adhesive (LTPSA) layers disposed on the same exterior panel surface generally alligned to each other and generally equi-distant to a fold line between the LTPSA layer.
