摘要： There is described a substantially planar self-supporting sheet (preferably an thermoplastic film e.g. formed from a polyolefin such as BOPP) comprising on at least one side thereof a substantially continuous adherent coating, thereon to create a barrier to oxygen, the coating comprising nano-particles, the sheet characterized in that: (a) the nano-particles form a substantially continuous phase on the sheet; and/or (b) the nano-particles are present in an amount of at least about 20% by dry weight of the coating; and/or (c) the coating is substantially free of polymeric binder, synthetic hydrophilic resin and/or a resin with a hydrophilic/hydrophobic character. The coated sheets have a high oxygen barrier, with preferred OTR values (at 23° C. and 0% RH)
摘要翻译：描述了一种基本上平面的自支撑片材（优选例如由诸如BOPP的聚烯烃形成的热塑性膜），其至少在其一侧上包含基本上连续的粘附涂层，以形成对氧的屏障，颗粒，其特征在于：（a）纳米颗粒在片材上形成基本上连续的相; 和/或（b）纳米颗粒以涂层的干重至少约20％的量存在; 和/或（c）涂层基本上不含聚合物粘合剂，合成亲水树脂和/或具有亲水/疏水特性的树脂。涂覆的片材具有高的阻氧性，优选的OTR值（在23℃和0％RH）<10cm 3 / m 2 /天。优选的纳米颗粒是诸如淀粉的生物聚合物，并且涂层优选基本上不含已经发现降低氧阻隔效能的蜡。也已经发现小分子或低聚物如生物共聚物（例如蔗糖）的组分的涂层增强颗粒涂层的氧阻隔性能，无论颗粒是微米还是纳米尺寸。还描述了涂料组合物，涂膜，涂布方法和包装制品。
