## Abstract

An improved reefer wall panel having better foam adhesion includes purposefully spaced gaps in the looped sections to be foamed. Such spaced gaps may extend horizontally, vertically, diagonally or in combinations of directions. These gaps (random or patterned) may be applied to the whole of a reefer panel or to just the more vulnerable lower sections where traffic impact during loading/unloading is more common and/or where delamination is known to occur more frequently. A method of reefer panel manufacture with such spaced gaps is also disclosed.

## Claims

### Claim 1

An improved reefer wall panel having better foam adhesion thereto, said wall panel comprising:
(a) a woven wall substrate; and
(b) a plurality of fully looped sections secured at each loop end of the plurality of fully looped sections into the woven wall substrate, said plurality of fully looped sections adapted for extending in a first direction outwardly beyond the woven wall substrate, said woven wall substrate including one or more rows of purposefully spaced gaps in the plurality of fully looped sections before a thermoplastic resin is injected onto the woven wall substrate and the plurality of fully looped sections to make the reefer wall panel.

### Claim 2 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend substantially horizontal in the plurality of fully looped sections.

### Claim 3 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend substantially vertical in the plurality of fully looped sections.

### Claim 4 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend diagonally in the plurality of fully looped sections.

### Claim 5 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend randomly across the plurality of fully looped sections.

### Claim 6 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend in a preset pattern across the plurality of fully looped sections.

### Claim 7 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps have no loops extending upwardly from the woven wall substrate.

### Claim 8 (depends on 1)

The reefer wall panel of claim 1 wherein at least some of the rows of purposefully spaced gaps include one or more set of loops that are visibly shorter than adjacent loops in the plurality of fully looped sections extending upwardly from the woven wall substrate.

### Claim 9 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend in at least one of: high impact areas and high delamination areas of the reefer wall panel.

### Claim 10 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps extend in other than a high impact area or a high delamination area of the reefer wall panel.

### Claim 11 (depends on 1)

The reefer wall panel of claim 1 wherein the rows of purposefully spaced gaps range in size from about 1 to 10 inches high or wide.

### Claim 12 (depends on 11)

The reefer wall panel of claim 11 wherein the rows of purposefully spaced gaps range in size from about 3 to 5 inches high or wide.
