The use of renewable resources is currently an important driver in the development of novel polymeric materials for commodity uses. The proposed program will focus specifically on the development of blends, foams and multilayer assemblies of different biobased plastics. Modern packaging typically incorporates different materials that act synergistically to give the final product a balance of properties in terms of mechanical properties, gas barrier, product appearance, etc. This involves adhesives and complex interfacial modification strategies to bond materials together. These technologies are to be reinvented in great part for the emerging biobased materials. Therefore, this program will focus on reactive extrusion to develop biobased adhesives or in situ strategies to compatibilize alloys or multilayer assemblies of different biobased materials. The long-term benefits for society of biobased packaging will be the use of lower energy and GHG emission processes, the use of biodegradable materials in applications suitable for composting and a lower dependence on petroleum byproducts.

目前，可再生资源的利用是开发用于商品的新型聚合物材料的一个重要驱动力。拟议的计划将特别侧重于不同生物基塑料的混合物、泡沫和多层组件的开发。现代包装通常结合不同的材料，这些材料协同作用，使最终产品在机械性能、气体阻隔性、产品外观等方面达到性能平衡。这涉及粘合剂和复杂的界面改性策略，以将材料粘合在一起。这些技术将在很大程度上被重新发明，以适应新兴的生物基材料。因此，该计划将专注于反应挤出，以开发生物基粘剂或原位策略，以增容合金或不同生物基材料的多层组件。生物基包装对社会的长期好处将是使用较低的能源和温室气体排放过程，在适合堆肥的应用中使用可生物降解的材料，以及对石油副产品的较低依赖。
