Problems solved by technology

If both ends extended into the fin or lap seal 20, the profile of the zipper closure 12 would be too thick and would leave a gap AG in the fin or lap seal, which could trap air or the product enters the package 10 and escapes from the package 10
[0008] Additionally, the method of forming a pillow or side gusseted package is imprecise and it is nearly impossible to leave the exact amount of space on each end of the closure to form a properly sized fin or lap seal

Abstract

A flexible package having a closure device and a lap or fin seal is provided that reduces or eliminates an air gap present at the fin or lap seal portion of conventional packages. The package can include a film with a closure applied to the film. A bridge material is provided to the film to fill the air gap when the closure is in a sealed condition. The flexible package alternatively can include a film having a closure device applied to the film transverse to the first and second side edges of the film, with the first side edge portion extending into the fin seal such that at least a portion of the first side edge portion to eliminate an air gap between the fin seal and at least one of the first and second side edge portions.

Description

[0001] priority [0002] This application claims priority to and is entitled to U.S. Provisional Application No. 61 / 944,195, filed February 25, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to flexible packaging, and more particularly to packaging with lap or fin seals, and methods for forming and using the packaging. Background technique [0004] Flexible packaging is used to contain a wide variety of both solid and liquid commodities such as beverages, lawn products and food products. More and more packaging, including flexible packaging, is being used to contain and / or dispense food, liquid or medical products. [0005] Use a single zipper to lock components (for example, Seam strips, etc.) suffer from significant disadvantages in that the locking member is sealed to the web of material in the transverse direction and is folded and locked onto itself during package formation. When the ...
