    Abstract: Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

  • Patent number: 8591795
    Abstract: A method of making an article of a semiconducting material involves selecting a target thickness for the article and then submerging a mold into a molten semiconducting material for a submersion time effective to form a solid layer of semiconducting material over an external surface of the mold where the thickness of the solid layer is substantially equal to the target thickness. The submersion time is selected to be substantially equal to a transition time, which is determined from a plot of solid layer thickness versus submersion time for a mold having particular attributes, including mold composition, mold thickness and initial mold temperature. The transition time, and thus the submersion time, corresponds to a maximum in solid layer thickness in the solid layer thickness versus submersion time curve for the particular mold.

  • Publication number: 20130161872
    Abstract: The present disclosure is concerned with improving the appearance of graphics printed on a flexible polymer film which is subsequently heated to a forming temperature and then drawn into a mold to form a cavity adapted for the packaging of an item, typically a food item. The improvement is effected by reducing the heat transfer to the portions of the film carrying the graphics thereby reducing the formability of these portions so that they stretch less than the rest of the film which is drawn into the mold. Typically the film is heated by contact with a heated platen. In such cases the reduced heat transfer can be effected by having zones of a cooler temperature which are adapted to be in registry with the portions of the film carrying the graphics or by covering the portions of the heated platen in registry with these graphics with an insulating material such as Teflon tape. The mouth of the cavity can then be closed by sealing to another flexible polymeric film.

  • Patent number: 8342835
    Abstract: A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region.

  • Patent number: 8313683
    Abstract: A method for manufacturing a plastic laminated article comprising a surface layer of a sheet-like surface member and a synthetic resin backing material layer laminated on the surface layer, without causing a fracture or a reduction in wall thickness of the sheet-like surface member. When the male mold is pressed against the contact area of the sheet-like surface member, the temperature of the contact area of the sheet-like surface member gradually falls due to a thermal gradient between the male mold and the contact area of the sheet-like surface member. Simultaneously, the contact area of the sheet-like surface member is not heated directly. In addition, the direction of jet flow of a hot fluid is changed, by fluid guide surfaces, from the center of the sheet-like surface member to the outer periphery, of the sheet-like surface member.

  • Patent number: 8257636
    Abstract: A method and apparatus for reforming a portion of a blow molded plastic container includes directing energy from a heater onto the portion of the container so as to heat the portion while leaving the remainder of the container relatively unheated. The heated portion of the container is then engaged by a reforming tool having an embossed or imprinted characteristic on a contact surface of the reforming tool so as to reform the portion of the container and form a three-dimensional feature thereon which is not reproducible without using the method and/or apparatus of the present invention. Alternatively, the heated portion of the container is engaged by a reforming tool having a transferable element on a contact surface of the reforming tool so as to reform the portion of the container and transfer the transferable element to the portion of the container.

  • Patent number: 8052913
    Abstract: Process for the production of a polymeric article by: (a) forming a ply having successive layers, namely (i) a first layer made up of strands of an oriented polymeric material; (ii) a second layer of a polymeric material; (iii) a third layer made up of strands of an oriented polymeric material, wherein the second layer has a lower peak melting temperature than that of the first and third layers; (b) subjecting the ply to conditions of time, temperature and pressure sufficient to melt a proportion of the first layer, to melt the second layer entirely, and to melt a proportion of the third layer; and to compact the ply; and (c) cooling the compacted ply. The resultant articles have good mechanical properties yet may be made at lower compaction temperatures than articles not employing the second layer, leading to a more controllable manufacturing process.
