    • There is described a substantially planar, self supporting, sheet or film (optionally oriented) which comprises at least one layer comprising a first material which is very highly crystalline polymer (preferably polypropylene of 99% or greater isotacity) together with at least one second material in an amount sufficient to improve one or more of the barrier properties, mechanical properties and/or optical properties of the sheet. The second material comprises a (a) nucleating agent; (b) a polymeric material having a ring and ball softening point from about 110° C. to about 170° C. and/or (c) a hydrogenated resin such as dicyclopentadiene hydrogenated resin, a hydrogenated mixed monomer resin; and/or a resin obtainable from a mixture of a-methyl styrene, indene and/or vinyl toluene monomers. Processes for making such films and compositions for use in the process are also described. Such films are useful in shrink wrap applications for example wrapping tobacco products.
    • 描述了基本上平面的,自支撑的,片或薄膜(任选定向的),其包括至少一层,其包含第一材料,其是非常高度结晶的聚合物(优选具有99%或更高等渗性的聚丙烯)以及至少一种第二材料 其量足以改善片材的一种或多种阻隔性能,机械性能和/或光学性能。 第二种材料包括(a)成核剂; (b)具有环球软化点约110℃至约170℃的聚合物材料和/或(c)氢化树脂如二环戊二烯氢化树脂,氢化混合单体树脂; 和/或可由α-甲基苯乙烯,茚和/或乙烯基甲苯单体的混合物获得的树脂。 还描述了制备用于该方法的这种膜和组合物的方法。 这种膜可用于例如包装烟草制品的收缩包装应用中。

    • There is described a polymer film preferably selected from polyolefin, polyester, polyamide, acrylic, polystyrene, or polyurethane, where the film is coated with an ink-jet printable ink receiving layer which when ink-jet printed has an average percent increase in droplet size on the ink receiving layer of less than about 5% between about 0.2 and about 2.0 sec after printing. Also described are printable films optionally with the preceding property which have an inkjet printable top coat layer comprising A), B) or C) where: A) is at least one halogenated terpolymer obtained and/or obtainable from the following polymer precursors: (a) halogenated vinyl, optionally vinyl chloride; (b) vinyl ester, optionally vinyl acetate; (c) olefin, optionally ethylene; B) is at least one copolymer obtained and/or obtainable from two of the following polymer precursors (i) halogenated vinyl, optionally vinyl chloride; (ii) vinyl ester, optionally vinyl acetate; (iii) olefin, optionally ethylene; and C) is at least one a vinylidene halide copolymer obtained and/or obtained from (x) a PVdX polymer precursor; and (y) a functionalised acrylic polymer precursor which comprises an olefinic monomer substituted by one or more non-halogenated electronegative groups.
    • 描述了优选选自聚烯烃,聚酯,聚酰胺,丙烯酸,聚苯乙烯或聚氨酯的聚合物膜,其中该膜涂覆有喷墨印刷油墨接收层,当喷墨印刷时,液滴尺寸的平均百分比增加 在墨水接收层上,在印刷后约0.2和约2.0秒之间小于约5%。 还描述了任选具有前述性质的可印刷膜,其具有包含A),B)或C)的可喷墨印刷的顶涂层,其中:A)是由以下聚合物前体获得和/或可获得的至少一种卤化三元共聚物:(a )卤代乙烯基,任选氯乙烯; (b)乙烯基酯,任选的乙酸乙烯酯; (c)烯烃,任选的乙烯; B)是由以下两种聚合物前体得到和/或获得的至少一种共聚物:(ⅰ)卤代乙烯基,任选的氯乙烯; (ii)乙烯基酯,任选的乙酸乙烯酯; (iii)烯烃,任选的乙烯; 和C)是由(x)PVdX聚合物前体获得和/或获得的至少一种偏二卤乙烯共聚物; 和(y)官能化的丙烯酸类聚合物前体,其包含被一个或多个非卤代电负性基团取代的烯属单体。
