1. A recyclable expandable insulating liner comprising: (5) (1)

a web of multilayer cellulose-based material configured to form a one-piece box shape when expanded, comprising four side panels and a bottom panel, wherein each side panel is connected to adjacent side panels and the bottom panel, and at least one of the side panels comprise an intra-panel connection line connecting two sections of the panel.

2. The insulating liner of claim 1 wherein two of the side panels comprise an intra-panel connection line and the two side panels are opposite one another. (2) (0)

5. The insulating liner of claim 1 wherein the insulating liner is fully recyclable. (0)

6. The insulating liner of claim 1 further comprising a closure device. (0)

7. The insulating liner of claim 1 wherein the intra-panel connection is selected from taping, adhesives or sewing. (1) (0)

9. The insulating liner of claim 1 wherein the multilayer cellulose-based material comprises cellulose tissue materials. (1) (0)

11. A process to produce a recyclable insulating liner, the process comprising: (1) (4)

folding a web of cellulosic material in half, thereby forming a folded web comprising two side edges a top edge and a bottom folded edge;

connecting at least one of the two side edges along an intra-panel connection line to form a pouch comprising two bottom corner portions;

cutting out a parallelogram-shaped section in each of the two bottom corner portions, thereby forming a cut pouch comprising two unconnected bottom corner sections comprising free edges; and

expanding the cut pouch and connecting the free edges of both unconnected bottom corner sections to form straight edges.

12. The process of claim 11 wherein two of the side edges are connected along an intra-panel connection line to form the pouch comprising two bottom corner portions. (0)

13. A process to produce a recyclable insulating liner, the process comprising: (1) (5)

folding a web of cellulosic material in half, thereby forming a folded web comprising first and second side edges, a top edge and a folded bottom edge, the top edge and folded bottom edge being opposite one another;

connecting at least one side edge along an intra-panel connection line, thereby forming a pouch;

expanding the liner, thereby forming an expanded liner comprising four side panels and a bottom panel, each of the side panels being connected to the bottom panel and adjacent panels, wherein the at least one intra-panel connection line is located in a side panel comprising a side panel lower portion and side panel upper portion;

forming a first triangular pointed section comprising a base and an apex from the lower portion of a first side panel and contacting the first triangular pointed section with the side panel;

forming a second triangular pointed section comprising a base and an apex from the lower portion of a second side panel and contacting the second triangular pointed section with the side panel.

14. The process of claim 13 wherein two side edges are connected along intra-panel connection lines, the intra-panel connection lines are located in two side panels opposite one another, and the first and second triangular pointed sections are attached to the side panels opposite one another. (0)

15. A process to produce a recyclable liner, the process comprising: (1) (6)

(a) folding a web of cellulosic material in half, thereby forming a folded web comprising first and second side edges, a top edge and a folded bottom edge, the top edge and folded bottom edge being opposite one another;

(b) connecting at least one side edge along an intra-panel connection line, thereby forming a pouch;

(c) expanding the liner, thereby forming an expanded liner comprising four side panels and a bottom panel, each of the side panels being connected to the bottom panel and adjacent panels, wherein the intra-panel connection line is located in a side panel comprising a lower portion and an upper portion;

(d) forming a first triangular pointed section comprising a base and an apex from the lower portion of a first side panel, and detaching the first triangular pointed section from the pouch at its base thereby forming free edges;

(e) forming a second triangular pointed section comprising a base and an apex from the lower portion of a second side panel, and detaching the second triangular pointed section from the pouch at its base, thereby forming free edges

(f) connecting the free edges of the side panels.

16. The process of claim 15 wherein two side edges are connected along intra-panel connection lines, the intra-panel connection lines being located in two side panels opposite one another, and the first and second triangular pointed sections are attached to the side panels opposite one another.
