Abstract: A film liner is provided in the form of a sleeve having at least four conforming seal areas provided on the sleeve that joins at least four adjacent panels of the sleeve along a location that is spaced inwardly from the edges of the sleeve, and the conforming seal areas each have a length that is less than the length of the edge from which it is inwardly spaced. When the full perimeter conforming liner according to this invention lines a container, such as a cheese-making box, including a so-called Arena box, two mouths of this liner form cuffs over the peripheral edge of the container. When thus used, the interior surface has a lining surface that engages the full perimeter of the box such that the liner walls flatly overlie the box walls and the respective corner portions of this lining surface overlie and engage all of the vertical corners of the box.

Abstract: A film liner is provided in the form of a sleeve having a conforming seal area provided on the sleeve that joins opposing panels of the sleeve along a location that is spaced inwardly from an edge of the sleeve, and this conforming seal area has a length that is less than the length of the edge from which it is inwardly spaced. When the conforming liner according to this invention lines a container, such as a cheese-making box, the mouth of this liner forms a cuff over the peripheral edge of the container. When thus used, the interior surface including the conforming seal area of the liner provides a relatively flat, crevice-free surface for receiving cheese curd or like products, and excess paneling material is positioned underneath this conforming interior surface and out of contact with the product filling the container.

Abstract: Multi-layered enclosures are provided which include extruded tubing laminated between two extruded sheets of coextruded film in order to rapidly produce an unusually tough enclosure having longitudinal side walls that are free of internal seams while providing superior fluid barrier properties. When desired, the multi-layered enclosure is transformed into a multi-layered bag or pouch by sealing the multi-layered enclosure together along one or more locations interconnecting the longitudinal or side edges of the multi-layered enclosure to thereby cross seal together the sheets, the tubing, and the internal surfaces of the tubing.
