The present invention discloses a method of producing at least a pair of interlocking adjacent layers of a paper packaging product, the pair of interlocking adjacent layers being formed of a sheet of slit paper having a slit pattern, the slit pattern upon expansion, forming cells that include land regions that are inclined with respect to a plane of an unexpanded sheet. The method comprises slitting the sheet of slit paper with beveled blades that have a first wedge angle on one side of the blades and a second wedge angle on the other side of the blades, wherein the first wedge angle is wider than the second wedge angle to produce slits that upon expansion, produce the lands regions that have angles of inclination in a range for 50 to 85 degrees.

A support assembly for supporting a biological product (e.g., membrane) in an operative position. The support assembly has a base and a cover. A membrane receiving portion of the base defines a plurality of perforations that extend between top and bottom surfaces of the product receiving portion. The cover is releasably coupled to the base in a product-covering position in which the cover overlies the product receiving portion of the base. In the operative position, the biological product engages the top surface of the product receiving portion and the bottom surface of the cover.

A beverage system is provided that includes a cup having a frustoconical wall extending from a first end to a second end. The first end is coupled to a bottom wall and the second end defines a rim. Inner surfaces of the walls define a cavity. The rim defines an opening that is in communication with the cavity. A lid is coupled to the rim such that the lid covers at least a portion of the opening. A sleeve includes a collar that surrounds a portion of the frustoconical wall. The sleeve includes first and second arms. The arms each include a first end coupled to the collar and an opposite second end. The second end of the first arm directly engages the lid. The second end of the second arm directly engages the second end of the first arm when the second end of the first arm directly engages the lid to prevent the lid from being removed from the cup.

A stretched film, which has excellent impact resistance and oxygen barrier properties and which suppresses the number of pinholes after being bent, a packaging material using the same, and a method for producing the stretched film are provided. The stretched film contains from 80 to 5 parts by mass of a polyamide resin (B) relative to from 20 to 95 parts by mass of a polyamide resin (A), the polyamide resin (A) being an aliphatic polyamide resin, the polyamide resin (B) containing a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid, 70 mol % or more of the constituent unit derived from a diamine being derived from xylylenediamine, from 30 to 70 mol % of the constituent unit derived from a dicarboxylic acid being derived from an am-linear aliphatic dicarboxylic acid having from 4 to 8 carbons, and from 70 to 30 mol % of the constituent unit derived from a dicarboxylic acid being derived from isophthalic acid provided that a total of the constituent units derived from a dicarboxylic acid is not more than 100 mol %.
