- 1. A recyclable expandable insulating liner comprising:
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.
- 11. A process to produce a recyclable insulating liner, the process comprising:
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.
- 13. A process to produce a recyclable insulating liner, the process comprising:
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.
- 15. A process to produce a recyclable liner, the process comprising:
(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.
