A blank including a single rectangular sheet of paperboard having opposed top and bottom edges and opposed left and right edges. The sheet has a midline spaced equally from the left and right edges, with a cut that extends from the top edge to a point spaced from the top edge, and a fold line that extends from the point to the bottom edge. The sheet also has a first zone that extends from midline to right edge along the bottom edge, a second zone that extends from bottom edge to a line spaced from the top edge along the right edge, a third zone that extends from midline to left edge along the bottom edge, and a fourth zone that extends from bottom edge to the line along the left edge. The first and second zones are configured to join the third and fourth zones.

A mailer has an outer, longitudinally extending, biodegradable film with lateral edges folded on itself to form a pocket having an opening and sealable by a flap. An assembly is composed of an inner, longitudinally extending, biodegradable film having lateral edges and a longitudinal extending pad composed of textile cuttings and microbial and superabsorbent powders. The inner film extends longitudinally around the pad and is attached to the pad. The assembly is positioned in the pocket with the inner film being sealed to the outer film adjacent the opening to the pocket trapping the pad between the outer and inner films. Sealing tape is mounted on the inner film adjacent to the pocket to seal the pocket closed. The lateral edges of both the outer and inner films, which extend laterally beyond the pad, are heat sealed together. A container has an outer box an inner insulative layer. The insulative layer is made from flocked textiles and is mixable with absorbatives and antimicrobials.

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.

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.
