  • Publication number: 20070087089
    Abstract: A bacon package has a stiffener sheet formed of plastic having an inner layer of foam polystyrene and solid films of polystyrene on opposite sides of the foam layer and coextruded therewith to form a web. The web of coextruded plastic is fed through an embossing station which forms an embossment defining the outer periphery of the stiffener sheet and, if desired, a plurality of annular embossments within the periphery. The embossed extrudate is then cut with heated knives around each embossment to seal the edges defined by the embossments. Apparatus other than heated knives may be used for sealing the edges.

  • Publication number: 20060159879
    Abstract: The invention is concerned with a mufti-layer film structure (1), especially film label-structure having a shrinkability, produced preferably in the coextrusion process, with a first (3) and a second (4) outer layer and a third inner layer (2) between the first (3) and second (4) layer, all layers consisting essentially of polystyrene. In order to achieve an advantageous label stock, the invention proposes, that the first (3) and second (4) layer are by weight approximately 50-75% of the overall weight of the label-structure, that the overall thickness is in the range of 0.5 to at least 4 mils (0.012 to 0.102 mm) and that the first (3) and second (4) layer consist of general, purpose styrenic resin, whereas the third layer (2) is a modified tough polystyrene, such as “K-resin” of Philipps Petroleum Chemicals.

  • Publication number: 20050004978
    Abstract: A computer implemented method for on-line purchasing via the global Internet. At a node connected to the Internet, customer data usable to automatically complete an on-line purchase by the customer of an item from a seller is received and stored. From a server, via the Internet, information is published to a computer of the customer, from the seller, with respect to an item, including metadata for use in associating said customer data with a customer action to purchase said item. A purchase indication is received from the customer computer, including at least a portion of said metadata for use in associating a customer purchase action with the item and metadata for use in associating said customer data with said transaction. In response to receiving said metadata for use in associating a customer purchase action with the item, the purchase is automatically completed by processing said metadata associating said customer data.
