20140124973 | Polyester Film Having Latent Shrink Properties and Process for Producing Same - A film layer is disclosed that is capable of shrinking when subjected to energy, such as heat. The film layer, for instance, can be formed and then stretched in one or two directions at a relatively low temperature. In particular, the film is stretched while the film layer is at a temperature near the glass transition temperature of the polymer used to form the film. Drawing the film at a relatively low temperature has been found to improve the shrink properties of the film. In one embodiment, the film layer is comprised of a non-modified polyester, such as polyethylene terephthalate. For example, the polyethylene terephthalate can be made by reacting terephthalic acid with ethylene glycol or polyethylene glycol. | 05-08-2014 |
20130133743 | LAMINATE CONTAINING COATED POLYESTER FILM - A bonding material is described that is well suited to bonding polymer films, such as polyester films, to other substrates. In one embodiment, for instance, the bonding material can be used to bond a polyester film to a layer containing an ethylene-vinyl acetate copolymer to form a backing material for a photovoltaic device. The bonding material generally comprises a polymer component combined with a cross-linking agent. The polymer component may comprise an alkylene carboxylic acid copolymer, such as an ethylene acrylic acid copolymer or an ethylene methacrylic acid copolymer. In an alternative embodiment, the polymer component may comprise a phenoxy resin. The cross-linking agent, on the other hand may comprise an oxazoline polymer. | 05-30-2013 |
20110168325 | Process for Recycling Waste Film and Product Made Therefrom - The present disclosure is directed to a process for recycling film materials, and is particularly directed to collecting spent release liners for labels and constructing new release liner stock from the spent materials. In order to use the waste film, the film is subjected to a process for increasing the intrinsic viscosity. In addition, a coloring agent may be incorporated into the film in order to mask yellowing. In one embodiment, a multilayered composite film is formed. | 07-14-2011 |
20100294363 | Coated Polyester Film For Lamination to Ethylene-Vinyl Acetate Layers - A bonding material is described that is well suited to bonding polymer films, such as polyester films, to other substrates. In one embodiment, for instance, the bonding material can be used to bond a polyester film to a layer containing an ethylene-vinyl acetate copolymer to form a backing material for a photovoltaic device. The bonding material generally comprises a block copolymer combined with a coupling agent. The block copolymer generally contains a polyester segment in combination with a different polymer segment. The different polymer segment may comprise, for instance, polyethylene glycol polymer blocks. The coupling agent, on the other hand, can comprise a functional silane. The polyester segments on the block copolymer attach to the polyester film, while the silane coupling agent reacts with the second polymer blocks and reacts with a constitutent in an adjacent layer. | 11-25-2010 |
20100104844 | Flame Retardant Polyester Composite Film - A multi-layer composite film that has flame retardant properties. In one embodiment, the composite film includes a middle layer containing a fumable flame retardant. The middle layer is positioned between two outer film layers. The outer film layers also contain a flame retardant. The flame retardant contained in the outer layers, however, is different than the fumable flame retardant contained in the middle layer. The composite film can be used to produce numerous different articles, such as window treatments, labels, release liners, wrapping materials for the electronics industry, and the like. In one embodiment, a metallized layer may be adhered to one side of the composite film. | 04-29-2010 |

20090117307 | Tamper evident composite film - A tamper evident composite film is disclosed. The composite film contains a first film layer made from polyester adjacent to a second film layer made from a polyolefin, such as a low density polyethylene. If desired, the composite film can further include a third film layer positioned on the opposite side of the second film layer. The composite film is produced through a coextrusion process. In one embodiment, the composite film can be biaxially stretched prior to use. The composite film is constructed so that the first film layer will delaminate from the second film layer when the composite film is tampered with or otherwise mishandled. | 05-07-2009 |
