This project is about the development of high barrier multilayer sheets to be used in thermoforming. The multilayer structure of interest is PP/tie/EVOH/tie/PP. Since EVOH is expensive and because of sheet trims from the sheet process, its replacement and/or recycling could be highly beneficial both from cost and environmental points of view. The collaborating company in this project is E. Hofmann Plastics Inc., a medium size Canadian company based in Orangeville, Ontario and engaged in the production of multilayer sheets and their thermoforming into containers for food packaging. It seeks reducing the cost of the multilayer structures and better recyclability of its trims. Thus, the objective in this project is to develop PP based multilayer (or monolayer blend) sheet structures with high O2 barrier properties for containers thermoforming. Various strategies will be considered:

本项目是关于开发用于热成型的高阻隔性多层片材。感兴趣的多层结构是PP/tie/EVOH/tie/PP。由于EVOH是昂贵的，并且由于来自片材工艺的片材修剪，因此从成本和环境的角度来看，其更换和/或回收可能是非常有益的。该项目的合作公司是E。霍夫曼塑料公司，一家位于安大略奥兰治维尔的中型加拿大公司，从事多层片材的生产及其热成型为食品包装容器。它寻求降低多层结构的成本和更好的可回收性。因此，在这个项目中的目标是开发PP基多层（或单层共混物）片材结构具有高氧气阻隔性能的容器热成型。将考虑各种战略：
