Abstract: 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.

Abstract: A folded 3D shaped packaging product (30) is folded at at least one crease (22A, 22B, 22C, 22D, 22E) constituting a folding line in a 3D shaped product (20) formed by hot pressing of an air-laid blank (10) comprising natural fibers at a concentration of at least 70 % by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30 % by weight of the air-laid blank (10). The folded 3D shaped packaging product (30) is useful for cushioning and/or thermal insulation of packaged goods and can protect multiple sides of the packaged goods.
