The present invention provides a film for packaging chemical agents, which contains an oxyalkylene unit-containing polyvinyl alcohol resin (A) and a carboxyl-containing polyvinyl alcohol resin (B), and preferably further containing a sulfo-containing polyvinyl alcohol resin (C). This film shows fine solubility in water even after a long-term packaging of an acidic chemical agent or alkaline chemical agent, and is superior in mechanical strength. Thus, the film for packaging chemical agents of the present invention is suitably used for packaging a chemical agent, such as powdered soap, synthetic detergent, agricultural chemical, antibacterial, deodorant, insecticide and the like, which is cast into water when in use.
本发明提供了一种用于包装化学制剂的薄膜,它含有含氧烷基单元的聚乙烯醇树脂(A)和含羧基的聚乙烯醇树脂(B),最好还含有含磺基的聚乙烯醇树脂(C)。这种薄膜即使在长期包装酸性化学制剂或碱性化学制剂后,在水中的溶解性也很好,机械强度也很高。因此,本发明的化学制剂包装薄膜适用于包装化学制剂,如肥皂粉、合成洗涤剂、农用化学品、抗菌剂、除臭剂、杀虫剂等,这些化学制剂在使用时会被抛入水中。
