  • Patent number: 8937550
    Abstract: A container defines an interior volume, an opening into the interior volume, and a sealing surface bordering the opening. A closure assembly for the container comprises an imperforate sealable metal liner for covering a container opening in its entirety. A radio frequency identification tag includes a microprocessor electrically coupled with an antenna through mounting contacts extending from the microprocessor to the antenna for receiving, storing, and transmitting digitized information. Electromagnetic interference with receiving, storing, or transmitting of digitized information to or from the radio frequency identification tag is controllable by restricting electrical coupling of the microprocessor with the imperforate metal liner to the mounting contacts. When sealed over a container opening to cover a container opening in its entirety, the imperforate metal liner abates migration of fluids between a container interior volume and an exterior of a container.

  • Patent number: 8574695
    Abstract: The present invention is directed to a multilayer film having, as its main component, a hydroxy acid polymer with improved gas barrier and optional heat sealability. The oriented film of predominately hydroxy acid polymer having controlled shrink can be produced by melting and coextruding a hydroxy acid polymer with a much thinner layer of an amorphous aromatic copolyester to form a multilayer film that is quench cooled, then biaxially stretched at a process temperature above the glass transition and below the cold crystallization temperature of the hydroxy acid polymer. A heat-setting treatment with a controlled relaxation of the film above the hydroxy acid polymer glass transition temperature and below its melt temperature may be used to control shrinkage. The films thus obtained are vacuum metallized on the aromatic copolyester surface to produce environmentally friendly packaging from predominately renewable resources having improved gas barrier properties.

  • Publication number: 20130122268
    Abstract: A heat-sealable roll or pouch stock laminated barrier material is disclosed and comprises: a compostable first layer; a compostable, heat-sealable second layer; and a metallized compostable film disposed between the first and second layers. The first layer can be selected from: (i) compostable film; and (ii) a coating layer and a paper layer, the paper layer being disposed between the coating layer and the metallized compostable film. The first layer can be secured to the metallized compostable film with an adherent selected from adhesive and extrudate. The second layer can be selected from a hermetically-sealable film and an extrudate. When present, the hermetically-sealable film is secured to the metallized compostable film with an adherent selected from adhesive and extrudate.

  • Patent number: 8435634
    Abstract: A fabric batting tape (10) that is utilized to fuse two pieces of material (24,28) together. The fabric batting tape (10) is comprised of a knitted fabric strip (12) having an upper surface (14) and a lower surface (16), and a hot-melt adhesive (22) that is located on the lower surface (16). The two pieces of material (24,28) are placed together, with a side edge (26) of one piece of the material (24) abutting a side edge (30) of the other piece (28). A length of the knitted fabric strip (12) is placed on top of the two pieces of material (24,28) with the adhesive lower surface (16) contacting the upper surfaces of the two pieces of material. When heat and pressure are applied via a heating element to the fabric strip (12), the heat activates the adhesive thereby creating a secure permanent fuse which maintains the two pieces of material (24,28) together along with the knitted fabric strip (12).

  • Publication number: 20120312711
    Abstract: The present invention relates to generating a film suitable for medical packaging. The film is generated by blown film co-extrusion to form a multi-layer film which has a heat resistant layer, a barrier layer and a heat seal layer. The barrier layer includes a high barrier resin and a branched co-polymer. The high barrier resin has a density of at least 0.963 g/cm3. The barrier layer includes between 25% and 85% high barrier resin. The heat resistant layer may be comprised of polymers, papers and other materials. The heat seal layer, in some embodiments, comprises any of high density polyethylene and medium density polyethylene, or a combination thereof. In some embodiments, an additional laminate layer may be affixed to the heat resistant layer of the multi-layer film. The final film is between 3.0 and 3.8 mils in thickness, and has a moisture vapor transmission rate of less than 0.08.

  • Patent number: 8273447
    Abstract: A multilayer oriented film comprising at least one layer (a) comprising one or more polyesters and/or copolyesters characterized by a % of crystallinity higher than 15, an adjacent layer (b) comprising one or more polyolefin-based adhesive resins, and a layer (c) comprising one or more co-polyesters characterized by a % of crystallinity lower than 15, is positioned between said two layers (a) and (b) in such a way that one of the two principal surfaces of layer (c) is directly adhered to layer (a) and the other is directly adhered to layer (b). The presence of a co-polyester layer (c) of relatively low % crystallinity positioned between (co)polyester layer (a) and adhesive layer (b) remarkably increases the bond between the two layers (a) and (b) and prevents delamination problems in the oriented structure.
