Abstract

Claims (15)

1. An insulation structure having an insulation panel comprising:

an insulation core layer comprising at least one puffed polysaccharide unit;

first and second outer barriers disposed on opposing sides of the insulation core layer; and

at least one heat seal formed between the insulation core layer and the first and second outer barriers, wherein a first portion of the insulation core layer is permanently compressed with a first thickness from the at least one heat seal, the first thickness being less than a second thickness of the insulation panel at a second non-heat seal portion of the insulation panel, the first portion of the insulation core layer adhering to the first and second outer barriers at the at least one heat seal,

wherein a distance between the first and second outer barriers at the first portion of the insulation core layer is less than a distance between the first and second outer barriers at the second non-heat seal portion of the insulation panel.

2. The insulation structure of claim 1 , wherein the first outer barrier comprises a top barrier and the second outer barrier comprises a bottom barrier, the top barrier being positioned proximate to a top surface of the insulation core layer, and the bottom barrier being positioned proximate to a bottom surface of the insulation core layer, the top and bottom barriers extending in parallel with the insulation core layer.

3. The insulation structure of claim 2 , wherein the at least one heat seal comprises a first centrally disposed heat seal positioned away from a perimeter of the insulation panel.

4. The insulation structure of claim 1 , wherein the first and second outer barriers are continuous outer barrier comprising a top barrier portion and a bottom barrier portion, the top barrier portion being positioned proximate to a top surface of the insulation core layer, and the bottom barrier portion being positioned proximate to a bottom surface of the insulation core layer, the top and bottom barrier portions extending in parallel with the insulation core layer.

5. The insulation structure of claim 4 , wherein the at least one heat seal comprises a first centrally disposed heat seal positioned away from a perimeter of the insulation panel.

6. The insulation structure of claim 1 , wherein the at least one heat seal comprises a first lateral seam that separates the insulation panel into first and second sections that are foldable relative to one another along the first lateral seam.

7. The insulation structure of claim 6 , wherein a portion of the at least one puffed polysaccharide unit extends into the first and second sections.

8. The insulation structure of claim 1 , wherein the at least one heat seal comprises a plurality of mechanically-formed heat seals that at least partially enclose one or more central cavities of the insulation panel.

9. The insulation structure of claim 8 , wherein the plurality of mechanically-formed heat seals separate the one or more central cavities from one or more peripheral cavities of the insulation panel, and a portion of the insulation core layer is disposed within each of the one or more peripheral cavities.

10. The insulation structure of claim 9 , wherein the plurality of mechanically-formed heat seals further comprise at least one heat seal formed in a first orientation with respect to the insulation panel, at least one heat seal formed in a second orientation with respect to the insulation panel, and at least one outside edge seal, wherein the plurality of mechanically-formed heat seals define a plurality of sealed sections of the insulation panel.

11. The insulation structure of claim 10 , wherein the plurality of scaled sections comprise a diamond pattern with respect to an outside edge of the insulation panel or a square pattern with respect to the outside edge of the insulation panel.
