This Small Business Innovation Research (SBIR) Phase I project will create a sustainable film to keep food fresh in flexible packaging. This project advances the use of abundant woody biomass residue, typically drawn from residue from forestry, agriculture, or building demolition, for a new plastic film This bioplastic film will address global demand for lightweight, fresh food packaging that is environmentally sound. Vapor barrier, flexible packaging is a $30B/yr global market, and the US produces 1B tons/yr of woody biomass - ample to supply the global demand for high barrier packaging. This project makes renewable, high barrier packaging from cellulose by deconstructing it to the sugar levoglucosan and then precisely re-polymerizing a nanostructured film with intrinsic strength, flexibility, temperature resistance, and vapor barrier properties. The innovation is biobased, poly(2,3)Glucose thermoplastic with intrinsic vapor barrier properties. Without laminations, crosslinks, or additives poly(2,3)Glucose biodegradable thermoplastic can be continuously recycled or decomposed in the environment. A recent breakthrough in the cost of pyrolyzing lignocellulose to levoglucosan makes levoglucosan cost competitive with fossil fuel feed stocks.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究（SBIR）第一阶段项目将创造一种可持续的薄膜，以保持食品在软包装中的新鲜。该项目推进了大量木质生物质残渣的使用，通常来自林业、农业或建筑物拆迁的残留物，用于新型塑料薄膜。这种生物塑料薄膜将满足全球对环保的轻质新鲜食品包装的需求。蒸汽屏障软包装是一个价值300亿美元/年的全球市场，美国每年生产10亿吨木质生物质——足以满足全球对高屏障包装的需求。该项目将纤维素分解为左旋葡聚糖，然后精确地重新聚合成具有固有强度、柔韧性、耐温性和蒸汽阻隔性的纳米结构薄膜，从而制造出可再生的高阻隔包装。该创新产品是生物基聚（2,3）葡萄糖热塑性塑料，具有固有的蒸汽阻隔性能。无需层压、交联或添加剂，聚（2,3）葡萄糖可生物降解热塑性塑料可以在环境中连续回收或分解。最近在热解木质纤维素到左旋葡聚糖的成本上取得了突破，使得左旋葡聚糖的成本与化石燃料原料具有竞争力。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
