20090017320 | Using branched polymers to control the dimensional stability of articles in the lamination process - Disclosed are laminated articles comprising a first polymer layer and a second polymer layer having an inclusion embedded between the layers, wherein at least one layer comprises a branching agent to improve dimensional stability during the lamination process. Disclosed are laminated articles comprising a first polymer layer and a second polymer layer having an inclusion embedded between the layers, wherein at least one layer comprises a copolyester comprising a branching agent to improve dimensional stability during the lamination process. Also disclosed are methods of laminating a first layer and a second layer with an inclusion between the layers to form a laminated article with an embedded inclusion, wherein at least one layer comprises a copolyester comprising a branching agent. | 01-15-2009 |
20090208765 | Thermoplastic Olefin Polymer Blend and Adhesive Films made Therefrom - The invention includes a multilayer film having at least 2 layers: (A) an adhesive layer comprising at least 40 weight percent of an ethylene/alkyl acrylate copolymer having a Vicat point (ASTM D 1525) of no more than 40 centigrade (° C.), at least 1 and at most 10 weight percent of an ethylene/alpha, beta-ethylenically unsaturated carboxylic acid copolymer, and at least 20 weight percent of a low density polyethylene, and 0 to at most 7 weight percent filler, hereinafter referred to as composition A; and (C) a barrier layer comprising at least 90 weight percent high density polyethylene, hereinafter referred to as composition C, in each layer, the percentages being based upon combined weight of polymers and filler and selected to total 100 percent by weight. Preferably the film further comprises at least one layer (B) a core layer comprising at least 20 weight percent linear low density polyethylene (LLDPE), at least 20 weight percent low density polyethylene different from LLDPE, at least 10 weight percent high density polyethylene and 0 to at most 5 weight percent filler, hereinafter referred to as composition B, the percentages being based upon combined weight of polymers and filler and selected to total 100 percent by weight. Such a film is useful to protect surfaces and preferably adheres when needed for protection and is removable after protection is no longer desired. Preferably, the film curls to an extent sufficient to help protect the edges of the protected surface. | 08-20-2009 |
20110111242 | METHOD FOR FORMING MULTILAYER COATING FILM - The invention offers methods for forming multilayer coating film excelling in smoothness, distinctness of image, water resistance and chipping resistance, the methods comprising successively applying onto a coating object a water-based first coloring paint and a water-based second coloring paint, and simultaneously heating and curing the resultant first colored coating film and second colored coating film, in which the water-based first coloring paint comprises hydroxy-containing polyester resin, curing agent, and water-dispersible acrylic resin which is obtained by polymerization of a monomer component comprising 30-100 mass % of C5-22 alkyl-containing polymerizable unsaturated monomer and 0-70 mass % of polymerizable unsaturated monomer other than the C5-22 alkyl-containing polymerizable unsaturated monomer. | 05-12-2011 |
20120107630 | Branched Aliphatic-Aromatic Polyester Blends - Compositions of PHAs with aromatic/aliphatic polyester are described and methods of making the same. | 05-03-2012 |
20120315499 | RELEASE FILM - The object of the present invention is to provide a release film in which the oligomer precipitation from the film surfaces constituting the release film in the respective film processing steps such as an adhesive-applying step of, drying step and sticking step is reduced as possible and it can be attained to improve the continuous production of film. | 12-13-2012 |
20130143053 | MULTILAYER BARRIER FILM HAVING COATING COMPOSITION WITH ORGANIC PARTICLES - A moisture vapor and oxygen transmission resistant flexible film has a polymeric base layer and a barrier layer of discrete particles of a first organic polymer dispersed throughout a matrix of a second organic polymer. Preferably, the first and second polymers are water insoluble and water soluble, respectively. The barrier layer is formed by depositing onto the base layer a coating composition of finely divided insoluble organic polymer particles suspended in an aqueous solution of the water soluble organic polymer, a crosslinking agent and surfactant. The coating composition is heated to crosslink the barrier layer polymers and evaporate solvent to provide a barrier film suitable for packaging applications. Optionally, the film can be metalized to increase barrier properties. | 06-06-2013 |
