One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. The visually-distinct contact areas being of a uniform gauge and configured to separate before either of the first film or the second film fails when subjected to peel forces.

A padded mailer includes elongated air cells 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.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

A shipping mailer includes a main body having a first wall and a second wall that are folded together and sealed along sealed side edge portions of the main body. The shipping mailer has a closed first end portion and a second end portion having an opening sealable by a closure. The main body is made of a single-face corrugated material including a liner layer and a fluted layer. The main body includes a center fold line at the closed first end portion from which the first and second walls extend. The fluted layer includes a plurality of flutes extending parallel to the center fold line, and flutes of the first wall nest with flutes of the second wall. The fluted layer includes a plurality of preformed longitudinal fold lines formed in the flutes, and the preformed longitudinal fold lines are offset inwardly from the sealed side edge portions.

A method and system provide a folded mailer system which can house / enclose a container which houses a liquid. The folded mailer system meets the requirements /standards as set forth by the USPS for first-class machinable mail. While the folded mailer system meets the USPS requirements / standards for first-class machinable mail, the folded mailer system may also meet the requirements / standards for machinable mail in other jurisdictions outside of the United States. The mailer system may include a container capable of holding a liquid and a structure for holding the container when the container is shipped. The structure may have at least two sections which are folded on to each other when the container is shipped. The container and structure may be machinable within an automated mailing system that is run by the USPS.

A padded mailer includes a pouch formed by front and rear sheets, each including a bottom edge, a top edge, and opposing side edges. The sheets are connected along their bottom edges and each of their side edges to define an interior space. The top edges of the sheets are unconnected to form an opening into the interior space. The padded mailer also includes a liner disposed in the interior space, including an expandable sheet having a bottom edge, a top edge, and opposing side edges. The bottom edge of the expandable sheet is secured adjacent the bottom edges of the front and rear sheets, and the top edge and the side edges of the expandable sheet are unsecured to the front and rear sheets. Pulling the top edge of the expandable sheet relative to the pouch causes the expandable sheet to expand and increase the thickness of the liner.

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.

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.
