Problems solved by technology

When in use, particulate products contained in flexible packaging (such as cookie crumbs, coffee, shredded cheese, etc.) will stick to the high-tack PSA, reducing the effectiveness of its adhesive
Additionally, consumers may find sticking to the PSA undesirable
One attempt to solve this problem is to use a lower tack PSA, but as mentioned above this also often increases the likelihood of delamination from the packaging film

Embodiment Construction

[0035] Embodiments provided herein relate to packaged products, particularly reclosable packaged products using a low-tack adhesive region (or region) attached to at least one exterior surface or panel of the package (and any select at least one internal surface) as a fastener that is self-adhesive but will not adhere to a different surface. In some embodiments, the package can have at least one seal that acts as a gas and moisture barrier for an extended period of time. The LTPSA regions can be oriented so that they are adjacent to each other to seal the package when it is reclosed. Embodiments can be easily opened and reclosed / resealed while maintaining the integrity of the package. Features of embodiments of the present invention may include product containment, enhanced product freshness, and in some embodiments reduced headspace above the product and reduced package size as the product is removed. Embodiments of the present invention provide low-cost refurbishment compa...

Abstract

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.

Description

technical field [0001] The present invention relates generally to reclosable fasteners for flexible packaging, and in particular to low tack adhesive reclosable fastener systems for flexible packaging. Background technique [0002] Packaging, especially flexible packaging, can be used to hold food and other consumer products for shipping and storage. Flexible film packaging can have many advantages. It can be manufactured at a much lower cost than rigid containers, is lightweight (which results in reduced shipping costs), and can be easily packaged, resulting in reduced storage space compared to other types of rigid packaging. [0003] Despite these advantages, the freshness and tightness of the product within the package can be an issue when more product is provided than the consumer requires for a single use. Several types of closures and fasteners are available for reclosing previously opened flexible packages. Typically mechanical reclosable fasteners are used, such a...
