    • The polymer composition is used for packing products of the chemical, food and other industries. The packing material obtained from the polymer composition has a wide range of application and controllable decomposition of the packages in water medium, ensuring environmental cleanness and recycling of the material.The polymer composition for packing materials contains polyvinylalcohol and water, and, according to the invention, it also contains polyvinylacetate dispersion, methylcellulose, carboxymethylcellulose and glucose in the following proportions of the components in % by weight: polyvinylalcohol 32 - 84, polyvinylacetate dispersion 10- 57, methylcellulose 3.0 - 5.8, carboxymethylcellulose 2.0 - 4.2, glucose 0.5 - 2.3, and water 0.5 - 6.0. The method for producing packing materials from the polymer composition includes the preparation of a dry mixture or viscous mass and moulding. According to the invention, before or after the moulding the material is treated successively with aqueous sodium tetraborate solution and aqueous formaldehyde solution.
    • 聚合物组合物用于包装化学,食品和其他行业的产品。 由聚合物组合物获得的包装材料在水介质中具有广泛的应用范围和可分解的包装,确保材料的环境清洁和再循环。包装材料的聚合物组合物含有聚乙烯醇和水,根据本发明 ,它还包含以下重量比的组分的聚乙酸乙烯酯分散体,甲基纤维素,羧甲基纤维素和葡萄糖:聚乙烯醇32-84,聚乙酸乙烯酯分散体10-57,甲基纤维素3.0-5.8,羧甲基纤维素2.0-4.2,葡萄糖0.5-2.3, 和水0.5-6.0。 从聚合物组合物制造包装材料的方法包括制备干混合物或粘性物质并模塑。 根据本发明,在模塑之前或之后,依次用四水硼酸钠水溶液和甲醛水溶液处理材料。
