摘要:
A cigarette filter, process to manufacture, wherein a low application temperature ethylene copolymer based hot melt adhesive is applied to porous and/or nonporous plugwrap paper. As used herein, low application temperatures are temperature between 200null F. and 300null F. (93null C. and 149null C.), preferably, 240null F. to 275null F. (115null C. to 135null C.).
摘要:
An improved decorative laminate and method for making the improved decorative laminate having a protective layer, an embossable layer, and a substrate layer; the protective layer being a transparent tough resin material such as polyvinylidene fluoride (PVDF) with a design printed thereon, the embossable layer being a pigmented embossable resin, and the substrate layer being a fiber material. As a result of the pigmentation of the embossable layer, preferably with the predominant color of the design, scratches through the protective layer are not particularly noticeable since the pigmented embossable layer will be exposed which matches the predominant color of the design.
摘要:
Polymeric articles, including membranes, with surfaces having a desired chemical functionality are created by surface segregation of a branched component blended with a compatible, matrix base component, the branched component having the desired chemical functionality. In particular, hydrophilic surfaces are created via surface segregation of a branched hydrophilic copolymer blended into a polymer matrix. The use of branched molecular architecture provides a thermodynamic mechanism for the segregation of the hydrophilic species to the surface and a means for achieving a high surface coverage of the hydrophilic moiety. The branched hydrophilic copolymer can be defined by a random copolymer including two or more methacrylate or acrylate monomers, at least one of which features a short hydrophilic side chain, such as a polyethylene glycol side chain. The branched hydrophilic copolymer is compatible, and well-entangled, with the acrylate polymer matrix.
摘要:
Packaging laminate for packages for liquid foods having excellent liquid and oxygen gas barrier properties in which all included layers are biodegradable. The packaging laminate includes at least one liquidtight layer (11, 13) of homo or copolymers of monomers selected from a group consisting of lactic acid, glycol acid, lactide, glycolide, hydroxy butyric acid, hydroxy valeric acid, hydroxy caproic acid, valerolactone, butyrolactone and caprolactone, as well as an oxygen gas barrier layer (12) of ethylene vinyl alcohol, polyvinyl alcohol, starch or starch derivatives. The oxygen gas barrier layer is preferably applied by a dispersion coating process. The layers may be laminated directly to one another or indirectly by means of interjacent adhesive layers. The packaging laminate may also include a core layer of, for example, paper or paperboard, or a biopolymer. The invention also realises a method of producing the biodegradable packaging laminate according to the invention.
摘要:
A moisture vapor permeable, substantially liquid impermeable composite sheet material comprising a moisture vapor permeable monolithic polymeric film having a first side and a second side, a first nonwoven layer comprising a moisture vapor permeable powder-bonded nonwoven layer, said powder-bonded layer comprising a nonwoven web of fibers, wherein greater than 95 weight percent of the fibers in the nonwoven web are compatible with said polymeric film, said first nonwoven layer being adhered to the first side of the polymeric film by extrusion of said film onto said first nonwoven layer, and an optional second moisture vapor permeable nonwoven layer adhered to the second side of the film.
摘要:
The present invention includes biocompatible coatings and films for use on implantable medical devices and medical devices containing such coatings and films applied to a surface thereof, which coatings/films are present on the device in an amount effective to provide an inert surface to be in contact with body tissue of a mammal upon implantation of the device in the mammal, and contain a film-forming polyfluoro copolymer containing the polymerized residue of a moiety selected from the group consisting of vinylidenefluoride and tetrafluoroethylene copolymerized with a second moiety other than the first moiety, wherein the relative amounts of the polymerized residue of the first and second moieties are effective to provide the coating and films with properties effective for use in coating implantable med devices.
