非石油基食品包装生物降解塑料的研制方法及关键技术

Method and Key Technology in the Development of the Non-Petroleum Based Food Packaging Biodegradable Plastics

利用天然高分子(淀粉、纤维素、甲壳素等)制作的非石油基生物降解塑料具有显著的资源和环境优势,已被广泛应用于食品包装领域。现代高分子设计方法使科研人员摆脱了开发新聚合物时所需的大量实验工作,寻找到了一条合成改性的新捷径,从而加快了获得新聚合物的速度。天然高分子材料的改性技术、绿色合成技术和低成本技术是进一步发展非石油基食品包装生物降解塑料的三大关键技术。

Non-petroleum based biodegradable plastic produced from natural polymer （starch, cellulose, chitin, etc.） has significant advantages in the aspects of resource and environment. It has been widely used in the field of food packaging. Modem molecular design methods enabled researchers to get rid of a lot of experimental work required in the original development of new polymer, and find a new shortcut to the modified synthesis which has expedited the develop- ment of new polymer. Modified technology, green synthesis technology and low cost technology of natural high polymer material are three key technologies in the further development of non-petroleum based food packaging biodegradable plastics.
