An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

A method enabling the selection, modification and/or creation of polymer materials which can provide improved response to the application of local shear and/or extensional deformation inside the polymer melt in manufacturing technologies including injection molding, injection stretch blow molding, direct injection, extrusion blow molding, sheet extrusion, thermoforming, etc., is provided. A method for manufacturing a polymer article includes injecting or extruding molten polypropylene, polyethylene or polyester based polymer for converting it into semi-final shape while applying shear and/or extensional deformation on the polymer melt. Applying shear and/or extensional deformation on the polymer melt includes selectively modifying the flow path of the molten semi-crystallizable polymer as a function of local pressure profile over at least part of the flow path. Local pressure profile is a function of optimized response of the polymer melt to the applied local shear and/or extensional deformation over at least the part of the flow path.

A method of the selection, modification of existing, and/or creation of polyester based polymer materials, which provide improved response to the application of local shear and/or extensional deformation inside the polyester based polymer melt in injection stretch blow molding, is disclosed. A method for manufacturing a polymer article is also provided including injecting a molten polyester based polymer in a preform mold for converting it in a preform while applying shear and/or extensional deformation on the polyester based polymer melt. Applying shear and/or extensional deformation on the polyester based polymer melt includes modifying the flow path of the molten polymer as a function of local pressure profile over at least part of the flow path. The local pressure profile is determined as a function of optimized response of the polyester based polymer melt to the applied local shear and/or extensional deformation over at least said part of the flow path.

Systems, apparatuses, and methods to secure a film to a container are provided. An example sealing device utilizes film from a supply of film to seal a lid onto a container. Various sizes of containers are usable with some example sealing devices. Additional features, such as printing on the film and piercing the film for ventilation and/or insertion of a straw are contemplated. One or more markings along the film may be utilized for confirming that an approved film has been loaded into the sealing device. In response, various components or features of the sealing device may be appropriately enabled or disabled. The one or more markings may also be utilized to convey data to the sealing device regarding the installed film, such as for improved operation thereof.

A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.

Methods of forming a lightweight reinforced thermoplastic core layer and articles including the core layer are described. In some examples, the methods use a combination of thermoplastic material, reinforcing fibers and bicomponent fibers to enhance retention of lofting agents in the core layer. The processes permit the use of less material while still providing sufficient lofting capacity in the final formed core layer.

A method of joining overlapping thermoplastic roofing membrane components in which a first thermoplastic roofing membrane component and a second roofing membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces. Heat is generated in a metal substrate and transferred by thermal conduction from the metal substrate to overlapping portions of the first and second thermoplastic roofing membrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic roofing membrane component and a portion or more of the thermoplastic material of the second thermoplastic roofing membrane component. The molten thermoplastic material of the first and second thermoplastic roofing membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.
