20140199545 | HOT MELT ADHESIVE - The present invention provides a hot melt adhesive for high-speed coating and spiral coating at low temperature. The hot melt adhesive has excellent adhesion to polyethylene and nonwoven fabric, and is suitable for disposable products. The hot melt adhesive comprises: (A) a propylene homopolymer having a melting point of 100° C. or lower which is obtainable by polymerizing propylene using a metallocene catalyst; and (B) an ethylene-based copolymer. | 07-17-2014 |
20140370278 | MULTILAYER FILM COMPRISING CYCLIC OLEFIN COPOLYMER - Disclosed is a multilayer film structure, comprising, in order, a puncture resistant layer comprising at least one cyclic olefin copolymer (COC) and at least one ionomer or polyolefin, a tie layer and a sealant layer. The structure can be coextruded and can be prepared using a triple bubble process. | 12-18-2014 |
20140377548 | RETORTABLE EASY OPENING SEALS FOR FILM EXTRUSION - The multilayer film comprises a first outer layer which is heat sealable. The first outer layer comprises from 95 to 100 percent (by weight of the first outer layer) of a first polymer, said first polymer being derived from propylene monomer and optionally one or more comonomers selected from the group consisting of ethylene and C4-C8 alpha olefins. The first polymer should have a melting point of at least 125 C. The multilayer film further comprises an inner portion adjacent to the first outer layer. The inner portion may be a single layer or may comprise several layers. At least one layer of the inner portion comprises an elastomeric propylene based polymer (“EPBP”). Further at least one layer of the inner portion comprises a second polymer, wherein the second polymer is selected from the group consisting of high pressure low density polyethylene, high density polyethylene, ethylene acrylic acid copolymers, ethylene (meth)acrylic acid copolymers and combinations thereof. The second polymer may be together with the EPBP in the same layer or may be in a separate layer. It is also contemplated that the inner portion may optionally comprise one or more additional layers, which may or may not contain EPBP or the second polymer. The multilayer film further comprises a second outer layer arranged so that the inner portion is encapsulated between the first outer layer and the second outer layer. The second outer layer comprises a third polymer, wherein said third polymer is selected from the group consisting of homopolymer polypropylene, random copolymer polypropylene and impact copolymer polypropylene and blends thereof. | 12-25-2014 |
20150044456 | PRIMER COMPOSITIONS FOR OPTICAL FILMS - Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer. | 02-12-2015 |
20150104639 | Hot Melt Pressure-Sensitive Adhesives for No-Label Look Applications - A composition comprising a hot melt pressure-sensitive adhesive comprising a propylene-based polymer component, wherein the propylene-based polymer component has a MFR of greater than about 1,000 g/10 min to less than about 10,000 g/10 min, and free of or having a low block copolymer content. Also, an adhesive article comprising the composition. | 04-16-2015 |

20150310773 | FLUID ACTIVATABLE ADHESIVES FOR GLUE-FREE, LINER-FREE LABELS FOR GLASS AND PLASTIC SUBSTRATES AND METHODS OF USE THEREOF - Methods for applying a liner-free, or liner-less label, to a substrate, particularly glass or plastic (e.g., PET) substrates are described herein. The method includes applying an adhesive composition, such as a polymeric coating, to a label face sheet, activating the adhesive composition with an activating fluid, and contacting the label to the substrate. The activating fluid is preferably a mixture of water and one or more organic solvents, such as low molecular weight alcohols. In some embodiments, the labels exhibit a percent fiber tear greater than about 50, 55, 60, 65, 70, 75, 80, 85, 90, or 95% after one, two, three, four, or five minutes. In particular embodiments, the labels exhibits a percent fiber tear greater than 60, 65, 70, 75, 80, 85, 90, or 95% after two minutes. | 10-29-2015 |
