  • Patent number: 6491166
    Abstract: A heat shrinkable film package and a method for packaging food and non-food products is disclosed which includes a valve through which the package is evacuated during the heat shrinking step of the packaging process. Employing the valve of the present invention precludes the need for puncturing the film prior to heat shrinking. Thus, a wide variety of food products may be packaged in a manner more typically reserved for non-food products.

  • Publication number: 20020157350
    Abstract: A method of finishing an enclosure formed from sheet metal includes the step of providing a tube formed from a film of a heat shrink polymer. The enclosure is inserted into the tube. Heat is applied to shrink the tube about the enclosure. Another method of finishing the enclosure includes the step of providing a sheet of a heat shrink polymer. The sheet is wrapped about the enclosure. The wrapped sheet may be affixed to the enclosure mechanically, chemically, or some combination thereof. Heat is applied to shrink wrap the sheet about the enclosure. In various embodiments the heat shrink polymer comprises at least one of the following polymers: irradiated low density polyethylene (LDPE), polyolefin, poly-ethylene terephthalate (PET), poly-vinyl chloride (PVC), and fluoropolymers such as poly-tetrafluoroethylene (PTFE), poly-vinylidene di-fluoride (PVDF), fluoroethylenepropylene (FEP), and perfluoroalkoxy (PFA).

    Abstract: A method is provided in which two or more products are packaged together by wrapping a wrapper of, preferably, a heat-shrinkable plastic sheet material around them. The wrapper is applied so that its opposite edges either overlap and bond together by a contact adhesive, or both bond to one of the products. Optionally, the wrapper is of a heat-shrinkable plastic material, in which case heat may then be applied so as to shrink the wrapper so that the contained products are more firmly held together. It is then an easy matter for the consumer to remove the wrapper, by peeling apart the areas which are held by the contact adhesive. Instead of being positioned side-by-side, the products may be stacked one-on-top-of-the-other, and the wrapper applied around the two products where they meet.

  • Patent number: 6050058
    Abstract: The method for forming a packaging (1) for a plurality of containers (2) arranged in lines and rows involves wrapping the group of containers with a section of heat-sealable plastic film (3), the two end flaps of which overlap so as to be able to be heat-sealed with one another. Pre-cut lines (5), parallel to the direction in which the film itself extends, are formed beforehand in the film. The pre-cut lines are positioned at a distance from one another and, in the finished packaging, each pre-cut line is arranged between two adjacent rows of containers. One side of the film used is provided, in the position where a longitudinal pre-cut lines is already present or is to be formed, with a strip-shaped area which is not heat-sealable when it comes into contact with the film itself. The width of the strips which are not heat-sealable is chosen so as to cover the maximum overlapping imprecision due to the packaging machines.

  • Patent number: 6029423
    Abstract: In order to improve a process for producing plastic packaging, particularly using plastic sheets, lateral sections (14) projecting beyond goods to be packaged being at least partly shrunk by heat supply, so that heat-sensitive goods also can be packaged in an economical and visually attractive way, it is proposed that the heat supply be interrupted as soon as the shrinking process starts in an area of plastic packaging subjected to heat, and that mechanical pressure be exerted on the heated areas of plastic immediately afterwards. An apparatus for carrying out the process for producing plastic packaging has an uptake area, a heat supply device and pressure members (15).

  • Patent number: 6006909
    Abstract: A rope package designed and configured with a self-contained hanger for display in retail stores. The rope is designed to be coiled into a number of uniform coils. In coiling the rope, one coil is pulled away from the uniform coils to create a loop between the one coil extending outwardly and the other uniform coils. The coiled configuration is then wrapped tightly with a membrane to hold the coiled configuration together. The resulting rope package contains a self-contained hanger, through use of the loop, that is suitable for hanging for display in its individual capacity in retail stores.

  • Patent number: 6004605
    Abstract: A bone cap device for use over a meat cut having at least one exposed bone is provided. The meat cut is positionable inside a separate outer bag with the bone cap device cushioning the exposed bone from piercing the separate outer bag. The bone cap device comprises a first bone cap positionable over the first exposed bone. A second bone cap is positionable over the second exposed bone. A connection member connects the first bone cap to the second bone cap wherein the first bone cap and the second bone cap inhibits the first exposed bone and second exposed bone, respectively, from piercing the separate outer bag.

  • Patent number: 5993942
    Abstract: A packaging film which shrinks to form at least part of a package when exposed to heat. The packaging film includes a thin film substrate that contracts or shrinks when heated and which is substantially transparent to radiant energy. The film also includes a susceptor material carried by the film that is sufficiently opaque to radiant energy to absorb and transfer to the substrate enough heat energy to cause the substrate to shrink, when the film is exposed to a source of radiant energy. In one embodiment the packaging film takes the form of lids of beverage containers.

  • Patent number: 5943844
    Abstract: The present invention has several aspects. One aspect relates to a method of wrapping a package containing a food product which is attractive and serves to present the food product in an appealing setting. The package includes a preformed tray and a heat sensitive transparent film sheet which is attached at at least one attachment region to the tray without wrinkles in the film sheet. A packaging machine, a cutting and heating assembly and the package itself comprise the other aspects of the invention. In each case, the transparent film sheet is wrinkle free.

  • Patent number: 5850723
    Abstract: When packing articles, particularly sheet stacks, such as computer lists, for transportation and dispatch purposes in a film, thick stacks should be tightly enveloped with a shrink film envelope, so as to increase their transportation stability, whereas the envelope of thin stacks is to remain unshrunk, so as not to deform the stack. It is proposed that both types of articles be passed in the packing line through the shrinkage tunnel, but in the case of articles not to be shrunk by increasing the passage speed and/or decreasing the circulating air speed, the heat transfer conditions are reduced in such a way that no shrinkage occurs. It is also proposed to so control the welding dies or jaws of a longitudinal welding station as a function of the thickness of the articles that thinner packs are more tightly enveloped than thicker packs.

  • Patent number: 5820908
    Abstract: The present invention is concerned with apparatus and methods for packing and handling articles of produce and the like. The apparatus includes a uniquely designed produce basket and rack combination. The basket comprises a framework containing a basket opening. A flange is detachably attached to the framework and surrounds the basket opening. A pair of lugs extend out from the flange, and function as handles for carrying the basket or for pulling the flange to detach it from the basket framework. An air-permeable barrier is heat sealed to the flange to create a closure to the basket opening. The closure is first opened by detaching at least a portion of the basket flange from the framework and is closed by pulling the detached flange portion down around the opening of the framework and engaging a spur. The rack comprises a rack framework which includes a top end containing a plurality of rack openings.
