Abstract

An insulated bag includes a pair of opposing main panels; and a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag; the main panels and the side panels defined in an insulated blank, the insulated blank including a first paper layer; and a paper fiber pad coupled to the first paper layer, the paper fiber pad having paper reinforcement fibers interlocked with about 2% to about 25% by weight of a meltable PE/PP bi-component thermoplastic binder fiber distributed substantially randomly, wherein subjecting the repulpable shipping container to a repulpability test produces greater than 85% fiber yield.

Claims (25)

1. An insulated bag comprising:

a pair of opposing main panels; and

a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag;

the main panels and the side panels defined in an insulated blank, the insulated blank comprising:

a first paper layer; and

a paper fiber pad coupled to the first paper layer, the paper fiber pad having paper reinforcement fibers interlocked with about 10% by weight of thermoplastic binder fibers distributed substantially randomly, wherein subjecting the paper fiber pad to a repulpability test produces about 93% fiber yield; and

wherein a first portion of the thermoplastic binder fibers has a length of about 1 mm, and a second portion of the thermoplastic binder fibers has a length of about 6 mm.

2. The insulated bag of claim 1 , wherein:

the insulated blank further comprises a second paper layer;

the first paper layer is coupled to the second paper layer; and

the paper fiber pad is at least partially encapsulated between the first paper layer and the second paper layer.

3. The insulated bag of claim 2 , further comprising a handle assembly comprising a handle portion attached to a base portion, the base portion being laminated between the first paper layer and the second paper layer.

4. The insulated bag of claim 1 , wherein the insulated blank further comprises one of a recycling-compatible or water soluble adhesive layer disposed between the first paper layer and the paper fiber pad.

5. The insulated bag of claim 1 , wherein the paper fiber pad has a weight of about 1300 GSM.

6. An insulated bag comprising:

a pair of opposing main panels; and

a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag;

the main panels and the side panels defined in an insulated blank, the insulated blank comprising:

a first paper layer; and

a paper fiber batt coupled to the first paper layer, the paper fiber batt including paper fibers bound together by thermoplastic binder fibers; and

wherein subjecting the paper fiber batt to a repulpability test produces about 93% fiber yield; and

wherein a first portion of the thermoplastic binder fibers has a length of about 1 mm, and a second portion of the thermoplastic binder fibers has a length of about 6 mm.

7. The insulated bag of claim 6 , wherein the thermoplastic binder fibers makeup about 10% by weight of the paper fiber batt.

8. The insulated bag of claim 6 , wherein the thermoplastic binder fibers are meltable PE/PP bi-component thermoplastic binder fibers.

9. The insulated bag of claim 6 , wherein the paper fiber batt has a weight of about 1300 GSM.
