An envelope is configured to hold, support, and protect an article such as a blood bag during transportation under cryogenic temperatures. The envelope includes a single piece component (e.g., a monolithic component), including multiple panels that are configured to fold to form an enclosure that surrounds the article such as the blood bag for support and protection of the article such as the blood bag.

A shipping mailer has a first wall and a second wall that at least partially define an interior of the shipping mailer. The shipping mailer has a closed first end portion and a second end portion, the second end portion comprising an opening sealable by a closure. A plurality of corrugations are coupled to the first wall and to the second wall in the interior of the shipping mailer. The corrugations of the first wall and the corrugations of the second wall have respective preformed fold lines at the closed first end portion about which the first wall and the second wall are configured to fold when an object is inserted into the shipping mailer to create an end wall extending between the first and second walls at the closed first end portion of the shipping mailer.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

A method for producing an insulation material is described herein. The method includes mixing cellulose reinforcement fibers with thermoplastic binder fibers to form a mixture. In addition, the method includes applying heat to the mixture to melt the thermoplastic binder fibers such that the thermoplastic binder fibers bind the cellulose reinforcement fibers together to form a batt. The thermoplastic binder fibers make up about 0.5% to about 25% by weight of the batt. Furthermore, the method includes slicing the batt along a horizontal plane to form a first pad having a first thickness and a second pad having a second thickness. Each of the first and second thicknesses is greater than or equal to about 1/16 of an inch.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

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.

An envelope liner template having a first panel having a pattern inscribed therein and a second panel. The second panel is positioned below the first template and attached by a fastening mechanism. The fastening mechanism is adapted to secure a decorative sheet in place between the first panel and the second panel when a cutting implement cuts through the pattern and the sheet against the second template panel to form an envelope liner.

In the preferred embodiments, a paper cushioning product is provided that includes: a sheet of slit paper having a slit pattern, the slit pattern upon expansion forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet; the sheet of slit paper being configured such that expanding the sheet of slit paper with said slits produces land regions that have angles of inclination from the plane of the unexpanded sheet, with said land regions alternating on a row by row basis in forward and backward directions such that the slit pattern upon expansion includes an alternating cell opening pattern wherein each row opens in an opposite direction from an adjacent row. In preferred embodiments, the product further includes at least one of a) said sheet of slit paper is extensible paper that is extensible in a machine direction in a range of at least 3% and/or b) said sheet of slit paper includes slits configured such that upon expansion the slit sheet paper expands into an alternating row expansion pattern.
