    Abstract: A method of producing an improved insulated container stock, such as a cup is disclosed comprising the steps of providing a sheet of polymeric foam having a first surface and second surface; providing a paper sheet suitable for cup stock; extruding a molten polyethylene polymer or copolymer into a molten sheet of film directed between the paper sheet and a first surface of the foam sheet to form a three layer laminate of foam, film, and paper; directing the three layer laminate into a nip having a preset gap; pressing the layers of the three layer laminate entering the nip into adherent contact as the molten film solidifies to form a laminate of substantially uniform caliper exiting the nip; extruding a molten polymer, preferably a heat shrinkable polymer, as a fourth layer forming a molten sheet of film directed onto a second surface of the foam of the three layer laminate to form a four layer laminate of polyethylene film, foam, polyethylene film and paper; directing the four layer laminate into an additional nip having a preset gap; pressing the layers of the four layer laminate entering the nip into adherent contact as the molten polymer, preferably heat shrinkable polymer, solidifies; forming the four layer laminate into a container wall for surrounding an interior space, adding a bottom portion to form a cup, and optionally heat treating the formed cup to shrink the fourth layer of the four layer laminate.

    Abstract translation: 公开了一种生产改进的绝热容器坯料例如杯子的方法，包括以下步骤：提供具有第一表面和第二表面的聚合物泡沫片; 提供适合杯子的纸张; 将熔融的聚乙烯聚合物或共聚物挤出到定向在纸张和泡沫片的第一表面之间的膜的熔融薄片中以形成泡沫，薄膜和纸的三层层压体; 将三层层压体引导到具有预设间隙的辊隙中; 当熔融膜固化时，将进入辊隙的三层层压体的层压到粘合接触中，以形成离开辊隙的基本上均匀的卡尺的层压体; 挤出熔融聚合物，优选热收缩聚合物作为第四层，形成指向三层层压体的泡沫的第二表面的膜的熔融薄片，以形成聚乙烯薄膜，泡沫，聚乙烯薄膜和纸的四层层合物 ; 将四层层压体引导到具有预设间隙的另外的辊隙中; 将作为熔融聚合物（优选热收缩聚合物）的进入辊隙的四层层压板的层压到粘合接触中固化; 将四层层压体形成容器壁以围绕内部空间，添加底部以形成杯子，并且可选地热处理成形的杯以收缩四层层压体的第四层。

    Abstract: Beverage or food containers made from sheet material, and methods of making such containers. Such container comprises a layer of paperboard and an expanded foam layer applied as a coating in a liquid carrier, and affixed to a paperboard base layer. The expanded foam has a remote surface preferably defined by intermingled peaks and valleys. The sheet material can include a protective cover layer overlying the remote surface. Such cover layer can comprise paper, plastic film, or foamed thermoplastic. The sheet material can include a heat seal layer, with the heat seal layer overlying, and in surface-to-surface contact with, the foam layer such that the foam layer is between the paperboard and the heat seal layer. Preferred composition for the foam layer is PVDC or AMM.

    Abstract: Beverage and food containers made from sheet material, and methods of making such containers. Such container comprises a layer of paperboard and an expanded foam layer applied as a coating in a liquid carrier, and affixed to a paperboard substrate layer. The expanded foam has a remote surface preferably defined by intermingled peaks and valleys. The sheet material can include a protective cover layer overlying the remote surface. Such cover layer can comprise paper, plastic film, or foamed thermoplastic. The sheet material can include a heat seal layer, with the paperboard substrate layer between the heat seal layer and the expanded foam layer. Preferred composition for the foam layer is PVDC or AMM.
