    • The present invention comprises an impermeable coating on an organic substrate resulting in a material that is inert, environmentally safe, impermeable and fully compostable and biodegradable. The present invention, therefore, is ideally suited to meet the ever-growing demand for compostable containers, as used in the food, beverage, agricultural, consumer products, medical, and waste industries, for example, including vacuum packaging and anti-static packaging. A possible substrate, such as a cellulose or polyactide (PLA) film and a possible coating, such as a ceramic coating of SiO2 (silicon di-oxide), are derived from organic substances and, thus, both completely degrade under natural conditions. Moreover, this biodegradation can occur under compost conditions as defined in numerous international standards, including at least ASTM D 6400.
    • 本发明包括在有机基材上的不可渗透的涂层,得到惰性,环境安全,不渗透和完全可堆肥且可生物降解的材料。 因此,本发明理想地适合于满足对食品,饮料,农业,消费品,医疗和废物工业中使用的可堆肥容器的不断增长的需求,例如包括真空包装和防静电包装 。 可能的基材,例如纤维素或聚丙交酯(PLA)膜和可能的涂层,例如SiO 2(二氧化硅)的陶瓷涂层,衍生自有机物质,因此, 在自然条件下都完全降解。 此外,这种生物降解可以在许多国际标准中定义的堆肥条件下进行,包括至少ASTM D 6400。
