An assembly for the automated production of conical paper sleeves for plants uses paper stock precut in a trapezoid configuration which is continuously fed to the assembly. The precut sheets are folded diagonally twice to form a conical sleeve. The folding process includes application of an adhesive on the overlap of the folded sides to securely seal the sleeve. The precut sheets are transported along the assembly via a series of belts, rollers and electrical motors. The synchronization of the folding process and the application of adhesive is electronically monitored and controlled.

A process for producing bags comprising: feeding a bottom web, a first side web and a second side web in a conversion process, each of the webs having a first side edge and a second side edge, wherein the first side edge of the first side web is aligned with the first side edge of the second side web, the second side edge of the first side web is aligned with the first side edge of the bottom web, and the second side edge of the second side web is aligned with the second side edge of the bottom web, thereby forming an inverted T-shaped web comprising a base having first and second wing portions and a riser, wherein the first wing portion comprises the bottom web and first side web, the second wing portion comprises the bottom web and the second side web, and the riser comprises the first and second side webs; sewing the first side web to the bottom layer in the first wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the first side web; sewing the second side web to the bottom layer in the second wing portion with a repeating pattern comprising a truncated triangle having a narrow portion and wider portion, and a tab separating the triangles, wherein the narrow portion of the triangle points toward the second side edge of the second side web; contacting the first and second wing portions by folding them toward each other, thereby forming a folded web; rotating the folded web to the horizontal; sewing the first and second webs together in the riser with a repeating pattern comprising a flat-bottomed U shape with tabs separating the repeating U's, where the flat bottom of the U faces the first side edge of the first and second side webs, and the tabs separating the flat-bottomed U's are bisecting the tab separating the triangles in the first and second wing portions, thereby forming a web of sewn bags; cutting the web along the edge of sewn bags to remove the sewn portion corresponding to the flat bottom portion of the flat bottom U shape parallel to the edge, thereby forming a web of open top bags; and transversely cutting the web of open top bags at the middle of the truncated triangles and bisecting the repeating U's, thereby forming separate, open bags, and optionally scrap material.

A microwave popcorn package is described that includes unique combinations of low porosity paper, flexible adhesive with broad coverage, and narrowed seal configurations that combine together to address unique issues associated with interaction of the individual features.

A cushioned envelope is formed from a laminated material that includes a cushioning web and a shell web. The outer side of the cushioning web is laminated to the inner side of the shell web. A crimping adhesive is applied to first and second transverse seams of the inner side of the cushioning web. The laminated web material is crimped so that each of the first and second transverse seams on the inner side of the cushioning web is folded in on itself. The folded laminated web material is crimped at the first transverse seam and at the second transverse seam. The crimped laminated web material is cut at a location in the first transverse seam and at a location in the second transverse seam.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.
