## Abstract

An insulation panel has an insulation core layer disposed that includes at least a first particulate and a second particulate of a plurality of discrete puffed polysaccharide particulates that defines a plurality of voids within the core layer. The first particulate is at least partially adhered to at least the second particulate at one or more bonded areas without the use of external non-water-soluble adhesives.

## Claims

### Claim 1

An insulation structure having an insulation panel comprising:
an insulation core layer comprising at least one puffed polysaccharide unit;
one or more outer barriers disposed about the insulation core layer; and
at least one heat seal formed between the insulation core layer and the one or more outer barriers, wherein a first portion of the insulation core layer is compressed and thermoset with a first thickness, the first thickness being permanently 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 one or more outer barriers at the at least one heat seal.

### Claim 2 (depends on 1)

The insulation structure of claim 1, wherein the one or more outer barriers comprises a top barrier and 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.

### Claim 3 (depends on 1)

The insulation structure of claim 1, wherein the one or more outer barriers comprises 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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)

The insulation structure of claim 4, wherein a portion of the at least one puffed polysaccharide unit extends into the first and second sections.

### Claim 6 (depends on 1)

The insulation structure of claim 1, wherein:
the at least one puffed polysaccharide unit comprises a first puffed polysaccharide unit and a second puffed polysaccharide unit;
the at least one heat seal comprises a first heat seal and a second heat seal;
at least a first portion of the first puffed polysaccharide unit is adhered to a first region of the one or more outer barriers at the first heat seal; and
at least a first portion of the second puffed polysaccharide unit is adhered to a second region of the one or more outer barriers at the second heat seal.

### Claim 7 (depends on 6)

The insulation structure of claim 6, wherein the first and second puffed polysaccharide units do not contact one another.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 8)

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.

### Claim 10 (depends on 1)

The insulation structure of claim 1, wherein each of the at least one heat seal is positioned away from a perimeter of the insulation panel.

### Claim 11 (depends on 1)

The insulation structure of claim 1, wherein the one or more outer barriers only bond to the first portion of the insulation core layer.

### Claim 12 (depends on 1)

The insulation structure of claim 1, wherein:
the insulation panel further comprises an outer seal extending proximate at least a portion of a perimeter of the insulation panel.

### Claim 13 (depends on 12)

The insulation structure of claim 12, wherein the at least one heat seal comprises a plurality of heat seals centrally disposed away from the outer seal of the insulation panel.

### Claim 14 (depends on 13)

The insulation structure of claim 13, wherein the plurality of heat seals separate one or more central cavities from one or more peripheral cavities of the insulation panel, the one or more central cavities being defined between two or more of the plurality of heat seals and the one or more peripheral cavities being defined between one of the plurality of heat seals and the outer seal.

### Claim 15 (depends on 14)

The insulation structure of claim 14, wherein a portion of the insulation core layer is disposed within each of the one or more central cavities and the one or more peripheral cavities.

### Claim 16 (depends on 14)

The insulation structure of claim 14, wherein the at least one puffed polysaccharide unit comprises a singular puffed polysaccharide unit, and a portion of the singular puffed polysaccharide unit extends into each of the one or more central cavities and the one or more peripheral cavities.

### Claim 17 (depends on 14)

The insulation structure of claim 14, wherein the plurality of heat seals comprises a first lateral seam extending a full width of the insulation panel and separating the insulation panel into first and second sections that are foldable relative to one another along the first lateral seam.

### Claim 18 (depends on 14)

The insulation structure of claim 14, wherein the one or more outer barriers comprise paper or polymeric film.

### Claim 19 (depends on 17)

The insulation structure of claim 17, wherein the insulation panel is foldable along the first lateral seam.

### Claim 20 (depends on 1)

The insulation structure of claim 1, wherein the at least one puffed polysaccharide unit comprises a plurality of particulates each comprising at least about 20% by dry-basis weight of starch polysaccharides.
