Embodiment Construction

[0052] Referring to Figures 1a-1e, there is shown a multilayer freezer bag in accordance with the teachings of the present invention. The multi-layer freezer bag 10 generally has an outer bag 12 and an inner liner 14 . The outer bag 12 is defined by side closure edges 18 and 18' and a folded edge 20 along a first (bottom) end 22 of the outer bag. Along the second (upper) end 24 of the outer bag is provided a reusable closure 16 for opening the multilayer bag, the closure 16 having eg mating male and female members. Said inner liner 14 has sides 26 and 26' which, according to the embodiment of Fig. 1a, share a common seal with the sides of the outer bag, referenced 18 and 18'. The inner liner may also be freestanding (not welded) or, as shown in Figure 1e, have its sides 26 and 26' welded independently of the corresponding sides of the outer bag.

[0053] Referring specifically to Figures 1b and 1d, the inner liner 14 has two side walls 32 and 32' formed when the inner liner ...

Abstract

The present invention provides a freezer bag (10) comprising a multi-layered bag having at least one liner film (14) and an outer support bag (12). The liner film(s) have a first sidewall (32) and a second sidewall (321) attached along respective lateral edges forming edge seals (18, 181), each sidewall having a top edge, the outer support bag having two sidewalls (32, 321) attached together along respective lateral edges forming edge seals, each sidewall having top edges defining the opening to the multi-layered bag and the support bag having a folded edge (20) defining the bottom of the multi-layered bag, the top edge of at least one liner film being attached to an inner surface of the respective sidewall of the support bag wherein the liner film(s) are thermoplastic.

Description

technical field [0001] The present invention relates generally to the packaging of food products, especially meat. The present invention seeks to create improved functional "freezer bags" for repackaging and frozen storage of fresh meat by end users to reduce so-called "freeze burn". Other aspects of the invention include, for example, methods and materials for making freezer bags and methods of using freezer bags. Background technique [0002] The prior art reclosable plastic storage bags are relatively old fashioned. Today, plastic bags commonly available to the public are carded with a specific recommended "end use" (eg, storage bags, Heavy Duty Freezer Bags, vegetable bags, waste bags). The bags themselves are often labeled with their "end use" such as "ZIPLOC  BRAND weighted freezer bags". [0003] The term "freezer bag" herein refers to a bag that has an important functional use when storing food in a freezer. "Freezer bags" are commonly supplied in the following...
