摘要：
本申请大致是针对新型组合物和方法，用来制得生物可降解的、基于淀粉的、并且防水的制品。本申请的教导包括一组合物，其含有生物可降解纤维成分，其在干重基准下的含量范围从约5％到约40％；淀粉成分，其在干重基准下的含量范围从约40％到约94.5％；和添加剂成分，其在干重基准下的含量范围从大于0％到约15％。该添加剂成分可含有环氧化植物油、氢化甘油三酯、聚醋酸乙烯酯、聚(醋酸乙烯酯-乙烯)共聚物、聚(乙烯-醋酸乙烯酯)共聚物，或者其组合。
摘要（英）：

The present application is generally directed to novel compositions and methods used to produce a biodegradable, starch-based, water-resistant article of manufacture. The teachings include a composition comprising a biodegradable fiber component in an amount ranging from about 5% to about 40% on a dry weight basis, starch component in an amount ranging from about 40% to about 94.5% on a dry weight basis, and an additive component in an amount ranging from more than 0% to about 15% on a dry weight basis. The additive component can comprise an epoxidized vegetable oil, a hydrogenated triglyceride, polyvinyl acetate), polyvinyl acetate-ethylene) copolymer, poly(ethylene-vinyl acetate) copolymer, or a combination thereof.
