Abstract: A padded mailer includes ribs that provide stiffness, especially in the transverse direction. The increased stiffness helps prevent the mailer from flipping over during conveying, which would put a label on the underside of the mailer.

Abstract: In one embodiment, a packaging material wraps around an object so as to protect the object from damage. The material has a substrate and a plurality of adhesive members adhered to the substrate, each having a plurality of microspheres. The adhesive members are arranged on the surface in a pattern so as to define first and second pluralities of pairs of linear arrays of the adhesive members. The linear arrays of the first plurality are elongate along a first direction and are spaced from one another so as to define a first bending gap between the linear arrays in each pair of the first plurality. The linear arrays of the second plurality are elongate along a second direction, angularly offset from the first direction, and are spaced from one another so as to define a second bending gap between the linear arrays of each pair of the second plurality.
