  • Patent number: 8900700
    Abstract: The technical problem to be solved by this invention is to give the transfer film a laminar structure that gives no damage to the decorative layer and is resistant to impact, a long period of use, and extensive deformation caused by repeated squeezes. The objects of this invention are to provide the transfer film in which the decorativeness is never damaged by the cracking, abrasion, or peeling during the period of use and also to provide synthetic resin molded products decorated with this transfer film. The solution to the above-described technical problem is a transfer film comprising a base film of a synthetic resin, a protective film of another synthetic resin peelably laminated to the base film, an adhering layer to be adhered to an article to be decorated, and a printed or vapor-deposited decorative layer sandwiched between the protective film and the adhering layer.

    Abstract: Hydrophilic adhesive compositions are disclosed that contain a surfactant that is miscible, but not fully soluble in the polymer matrix of the adhesive. This permits the surfactant to continuously replenish at the surface of the adhesive as other surfactant is removed, such as when it is carried away by an aqueous sample flowing over that surface in an in-vitro diagnostic device, resulting in adhesive compositions that are inherently hydrophilic on their surfaces and do not rely on the bloom mechanism of known hydrophilic adhesives. This provides greater design options for in-vitro diagnostic device manufacturers, including the use of hydrophilic adhesive spacers in lieu of or in combination with hydrophilic top covers.

The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll.

  • Patent number: 8597715
    Abstract: A method of removing a target from a biological sample which involves placing a transfer surface in contact with the biological sample, and then focally altering the transfer surface to allow selective separation of the target from the biological sample. In disclosed embodiments, the target is a cell or cellular component of a tissue section and the transfer surface is a film that can be focally altered to adhere the target to the transfer surface. Subsequent separation of the film from the tissue section selectively removes the adhered target from the tissue section. The transfer surface is activated from within the target to adhere the target to the transfer surface, for example by heating the target to adhere it to a thermoplastic transfer surface. Such in situ activation can be achieved by exposing the biological sample to an immunoreagent that specifically binds to the target (or a component of the target).

  • 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.

  • Patent number: 8389117
    Abstract: Disclosed are hot-melt adhesives prepared from polyesters containing 1,4-cyclohexane-dicarboxylic acid as a diacid component and a diol component containing at least two diols chosen from 1,4-cyclohexanedimethanol, triethylene glycol, and diethylene glycol. These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.

  • Publication number: 20130052386
    Abstract: A sealing web including the following layer structure: a) a film containing polyvinyl chloride; b) a first adhesive; c) a polyethylene terephthalate film; and d) a second adhesive; wherein the layers are disposed in the sequence a), b), c), and d). The sealing web makes it possible to implement adhesion of a PVC web over a large area, without problems arising from the migration of the plasticizer from the PVC film to the adhesive, or in that said problems are at least greatly reduced.

  • Publication number: 20130034726
    Abstract: Fluid activatable adhesive compositions and activating fluid(s) for activating the adhesive composition are described herein. The adhesive compositions contain at least two polymers with different hydrophilicities. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate. The adhesive composition may contain particulate fillers which enable fast exhaustion of the activation fluid out of the adhesive when applied to a substrate, thereby allowing the hydrophobic polymers of the adhesive composition to achieve strong adhesion of the liner-free label to the paper or polymeric substrate. The particulate fillers may also function as anti-blocking agents when liner-free label media are tightly wound in a roll.

  • 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.

  • Publication number: 20120100368
    Abstract: A process for preparing a pressure sensitive adhesive using a modified planetary roller extruder is described. The process in accordance with one aspect of the invention is a continuous process that includes introducing primary raw materials comprising a non-thermoplastic elastomer into a planetary roller extruder, introducing a heat-activatable crosslinker into the planetary roller extruder for mixing with the primary raw materials, and compounding the primary raw materials and the heat activatable crosslinker to form an adhesive composition while maintaining the temperature of the adhesive composition between about 25° C. and about 100° C. The non-thermoplastic elastomer is masticated during compounding and at least some of the heat-activatable crosslinker remains generally unactivated and is available for later activation.
