摘要:
A coating for a polyolefin film is made from an acrylic polymer or ionomer resin and an ink receptive particulate such as a molecular sieve and/or a carbohydrate polymer such as cellulose, carboxymethyl cellulose or corn starch. The coating composition facilitates adhesion of ink to the polyolefin film.
摘要:
The present invention relates to a matte surface film comprising: (a) a base layer comprising high density polyethylene (HDPE); and (b) a matte surface layer comprising a blend of two or more incompatible polyolefins. In preferred embodiments, the matte surface layer comprises (i) a propylene homopolymer or propylene interpolymer and (ii) an ethylene homopolymer or ethylene interpolymer. The film possesses easy and improved cuttability and may be used for packaging and label applications.
摘要:
A process for thermal transfer printing on plastic films incorporating a coating composition is provided. The process includes providing plastic film having a coating composition including a binder of a polymer and/or copoylmer of carboxylic acid containing vinylic unsaturation, at least one finely divided particulate filler, and a surface active agent. A thermographic element such as a ribbon which includes a dye layer is then heated in the form of an image to be printed onto the plastic film, with the heating causing the dye layer to melt in the form of the image. The plastic film coated with the coating composition is contacted with the thermographic ribbon, and the dye layer is transferred from the ribbon to the plastic film. Such thermal transfer printing on coated plastic films provides for a multitude of uses such as plastic labels for outdoor use.
摘要:
A composite sheet of a film form base liner, a cured release coating laminated to at least one side of the base liner, and a skin, on the top-most portion of the base liner proximate to the release coating, comprising a polymer which is compatible with the base liner and contains pendant acid groups.
摘要:
High density polyethylene (HDPE) films, preferably containing blends of HDPE resins or microcrystalline wax, are oriented up to about two times in the machine direction and six times or more in the transverse direction to give films having good dead-fold and water vapor transmission characteristics making them highly suited for packaging, particularly for dry foods when coated with or coextruded with a heat sealable layer, e.g. Surlyn.
摘要:
Disclosed is a multi-layer film comprised of at least one high density polyolefin (HDPE) layer, at least one polyamide layer and an HDPE/polyamide adhesion promoting agent. The agent is substantially free of inorganic salt groups and it is a non-ionic product of a polymerization reaction of a C.sub.2 -C.sub.6 alpha-olefin with a monocarboxylic acid of the formulaR--COOHwherein R is an ethylenically unsaturated hydrocarbyl group.
摘要:
Opaque pearlescent polymer films, e.g., polypropylene, containing finely dispersed particles of an incompatible polymer, e.g., nylon, are improved by blending a polymer compatible with the polymer forming continuous film phase to alter its melt rheology and to cause dispersion of the incompatible polymer in small spherical particles with reduced stringiness.
摘要:
Multi-layer containers comprising an exterior layer of foamed or unfoamed polystyrene or poly(para-methylstyrene) which is not resistant to hot fat under microwave cooking conditions and an interior layer of 5 mils or less of an impact copolymer of at least 5 weight percent rubber and styrene or para-methylstyrene which serves as a heat and grease resistant layer rendering the container suitable for microwave cooking of fatty foods.
摘要:
Multi-layer containers are rendered resistant to hot fats under microwave conditions by coating the substrate which is not fat resistant with a cellulose ester layer such as cellulose acetate propionate.
摘要:
Blends of polyvinyl alcohol, and ethylene-vinyl alcohol copolymer containing a processing aid such as polyamide, polyurethane or polyoxazoline are melt extrudable into paper-like films having excellent oxygen barrier and grease resistance properties.
