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.

Fiber-based composite material for padded mailers and corresponding systems and methods are provided herein. A fiber-based composite includes a fiber-based backing material and a fiber-based padding attached to the backing material to provide cushioning for items within a mailer. The fiber-based padding is applied as a plurality of tubular structures, each defining a perimeter extending from a first point of attachment to a second point of attachment. The perimeter further defines an apex point which is spaced apart both laterally and vertically from a center point on the backing material that is between the first and second points of attachment. A plane connecting the center point and the apex point defines an angle with the backing material that is greater than 5 degrees and less than 75 degrees.

A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.

A wrapping material includes a substrate and a buffer layer, wherein the substrate has a first lateral edge and a second lateral edge, and the buffer layer has a third lateral edge and a fourth lateral edge. The buffer layer is stacked on the substrate. The first lateral edge of the substrate is tightly merged with the third lateral edge of the buffer layer, and the second lateral edge of the substrate is tightly merged with the fourth lateral edge of the buffer layer. A method of making a wrapping material includes: providing a substrate; stacking a buffer layer on the substrate; using a thermal cutting tool to cut the stacked substrate and buffer layer so that the substrate and the buffer layer are tightly merged at where they are cut as being melted by heat.

A packaging bag has a bag body formed from a flat web and has a first front wall and a second front wall as well as a stand-up bottom formed in a bottom section by folding and gluing the front walls. The flat web has a varnish coating on an outside of the bag body, wherein the first front wall has an adhesive region free of the varnish coating in the bottom section of the bag body.
