Natural packaging composition

A packaging material composition may be biodegradable and water soluble. The packaging material may include a biodegradable nonionic polysaccharide, a biodegradable ionic polysaccharide, and a plasticizer. Optionally, for a desired purpose, additional components may be added to the packaging material. Other components may include biocides, clays, metal oxides (i.e., titanium dioxide and zinc oxide), modified nanoclays, one or more cross-linkers, other functional agents, and residual solvents from the packaging material production process. 一种包装材料组合物可以是可生物降解的和水溶性的。该包装材料可以包括可生物降解的非离子多糖、可生物降解的离子多糖和增塑剂。可选地，为了期望的目的，可以将额外的组分添加到包装材料中。其他组分可能包括生物杀灭剂、粘土、金属氧化物(即二氧化钛和氧化锌)、改性纳米粘土、一种或多种交联剂、其他功能剂，以及来自包装材料生产过程的残留溶剂。
