Abstract
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.
Claims13
A process to produce a recyclable square or rectangular-bottom article, the process comprising:
- (a) folding a web comprising multilayer recyclable insulating cellulosic-based tissue material comprising fibers, thereby forming a tube structure made of the same material;
- (b) connecting at least one edge along an intra-panel connection line, wherein the web is compressed along the at least one edge to permanently pinch the edge, thereby forming a connected structure;
- (c) expanding the connected structure thereby forming a first side panel, a second side panel and a bottom panel;
- (d) forming a first section comprising a base and an apex from the lower portion of a first side panel and contacting the first section with the bottom panel;
- and
- (e) forming a second section comprising a base and an apex from the lower portion of a second side panel and contacting the second section with the bottom panel,
- wherein the process does not utilize outside materials from the web except for adhesives or fastening devices, nor are portions cut from the web and reattached, and
- wherein the recyclable square or rectangular-bottom article is produced without the use of thermoplastic heat-sealable materials.
A process to produce a recyclable square or rectangular-bottom article, the process comprising:
- (a) folding a web comprising multilayer recyclable insulating cellulosic-based tissue material comprising fibers, thereby forming a tube structure;
- (b) connecting at least one edge along an intra-panel connection line, wherein the web is compressed along the at least one edge to permanently pinch the edge, thereby forming a connected structure;
- (c) expanding the connected structure thereby forming a first side panel, a second side panel and a bottom panel;
- (d) forming a first section using folding, comprising a base and an apex from the lower portion of a first side panel and contacting the first section with the side panel;
- and
- (e) forming a second section using folding, comprising a base and an apex from the lower portion of a second side panel and contacting the second section with the side panel,
- wherein the process does not utilize outside materials from the web except for adhesives or fastening devices, nor are portions cut from the web and reattached, and
- wherein the recyclable square or rectangular-bottom article is produced without the use of thermoplastic heat-sealable materials.
A process to produce a recyclable square or rectangular bottom bag, the process comprising:
- (a) folding a web comprising recyclable insulating multilayer cellulosic-based tissue material comprising fibers;
- (b) connecting at least one edge along an intra-panel connection line, wherein the web is compressed along the at least one edge to permanently pinch the edge, thereby forming a connected structure;
- (c) expanding the connected structure thereby forming a first side panel and a second side panel
- (d) forming a bottom panel
- (e) forming a first section using folding, comprising a base and an apex from the lower portion of a first side panel and contacting the first section with the bottom panel or a side panel;
- and
- (f) forming a second section using folding, comprising a base and an apex from the lower portion of a second side panel and contacting the second section with the bottom panel or a side panel,
- wherein the process does not utilize outside materials from the web except for adhesives or fastening devices, nor are portions cut from the web and reattached, and
- wherein the recyclable square or rectangular-bottom article is produced without the use of thermoplastic heat-sealable materials.
