A textured mailer includes a first panel comprising at least a first paper layer; a second panel coupled to and facing the first panel and comprising at least a second paper layer; and an inner cavity defined between the first panel and the second panel, wherein at least one of the first paper layer and the second paper layer is formed as a textured paper layer configured to provide cushioning to contents of the inner cavity.

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 foldable template for forming an envelope includes a central panel, a top glue flap, a bottom glue flap, a first intermediate panel, a second intermediate panel, a first back panel, and a second back panel. The first intermediate panel extends from a first side of the central panel and is separated therefrom by a first curved crease. The second intermediate panel extends from a second side of the central panel and is separated therefrom by a second curved crease. The first back panel extends from the first intermediate panel and is separated therefrom by a third curved crease. The second back panel extends from the second intermediate panel and is separated therefrom by a fourth curved crease.

A method of forming a cushioning sheet includes forming a plurality of first sockets in a first layer; forming a plurality of second sockets in a second layer, each of the second sockets aligned with a corresponding one of the first sockets; positioning a cushioning insert within a void defined between each corresponding pair of the first and second sockets; and coupling the first layer to the second layer to retain the plurality of cushioning inserts within the voids.
