App. No. 16/044,504

Abstract

Claims (27)

1 . A multilayer packing liner apparatus useful for insulating, comprising:

a first outer layer;

a first bubble layer;

an interstitial layer; and

a second bubble layer.

2 . The apparatus of claim 1 , comprising a second outer layer directly contacting the second bubble layer.

3 . The apparatus of claim 1 , the first outer layer further comprising an outer side and an inner side, the inner side directly contacting a first side of the first bubble layer.

4 . The apparatus of claim 1 , the first bubble layer further comprising a first side and a second side, the second side directly contacting the interstitial layer.

5 . The apparatus of claim 1 , the second bubble layer further comprising a first side and a second side, the first side directly contacting the interstitial layer.

6 . The apparatus of claim 2 , the second bubble layer further comprising a first side and a second side, the first side directly contacting the interstitial layer, the second side directly contacting the second outer layer.

7 . The apparatus of claim 1 , the first outer layer further comprising MYLAR.

8 . The apparatus of claim 1 , the first bubble layer comprising polymeric material.

9 . The apparatus of claim 1 , first outer layer further comprising MYLAR, the first bubble layer further comprising polymeric material, and the interstitial layer comprising MYLAR.

10 . The apparatus of claim 1 , the first outer layer further comprising metallized polypropylene.

11 . The apparatus of claim 1 , the first outer layer further comprising a material selected from the group comprising MYLAR, metallized polypropylene, metallized polyethylene, and nylon, the first bubble layer further comprising polymeric material, and the interstitial layer comprising a material selected from the group comprising MYLAR, metallized polypropylene, metallized polyethylene, and nylon.

12 . The apparatus of claim 1 , the first bubble layer further comprising a polymeric structure configured to define a plurality of voids, sealed by the polymeric structure and the first outer layer and the interstitial layer, the plurality of voids substantially equally distributed across the first bubble layer.

13 . The apparatus of claim 12 , the second bubble layer further comprising a polymeric structure configured to define a plurality of voids, sealed by the polymeric structure and a second outer layer and the interstitial layer, the plurality of voids substantially equally distributed across the second bubble layer.

14 . The apparatus of claim 2 , the liner shaped and configured to form a container.

15 . The apparatus of claim 2 , the liner shaped and configured to form a bag having two sealed side edges and a bottom panel.

16 . The apparatus of claim 2 , the liner shaped and configured to form a foldable container.

17 . The apparatus of claim 1 , the first outer layer, the first bubble layer, the interstitial layer, and the second bubble layer configured to form an insulating container useful for maintaining a temperature in a range of temperatures suitable for storing food items.

18 . A method for forming a multilayer packing liner apparatus useful for containing food items, the method comprising:

attaching an outer layer in direct contact with a first side of a first bubble layer;

attaching an interstitial layer to a second side of the bubble layer, sealing voids defined therein by structural material of the bubble layer; and

attaching a second bubble layer directly the interstitial layer on a first side of the second bubble layer.

19 . The method of claim 18 , comprising attaching a second outer layer directly to a second side of the second bubble layer.

20 . The method of claim 18 , comprising forming the packing liner in the shape of a container or bag.
