—食品包装新概念
[摘要]:食品的包装及制作过程是一个再生产的过程,可能会引入污染及对环境造成二次污染,这是绿色食品包装发展中必须考虑的。绿色包装又可以称为无公害包装和环境之友包装,指对生态环境和人类健康无害,能重复使用和再生,符合可持续发展的包装。今年来随着生活质量的不断提高,人们对食品包装材料的要求也越来越高,因此新型环保的包装材料也越来越受到重视,目前应用最多的就是纸质包装材料、可降解包装材料、可食性包装材料和其他新型材料。使用绿色包装材料包装食品,可以提高食品的安全性,保护人类的健康,同时保护环境,对社会的可持续发展起着重要的作用。因此走绿色包装之路是符合实际的是可行的。

地球的自然资源并非取之不尽、用之不竭,每一种物质的形成都需要漫长的时间。包装行业对资源的需求量巨大,如美国用于包装的纸和纸板占纸制品总量的90%,这充分说明包装消耗着相当数量的自然资源。森林的大量采伐已严重破坏地球的气候和生态平衡,我国森林面积已不足国土总面积的14%

包装在促进商品经济发展的同时,对环境造成的危害也日趋严重。据统计资料表明:我国县以上城市固态垃圾年产量约2亿t,,;其中包装废弃物发达国家约占垃圾总量的1/3,我国约占1/10,即每年达2000万t。据日本调查表明:%,%,。在我们生活的周边环境中,塑料造成的白色污染到处可见,按照塑料在自然界的降解速度推算,我们生活的城市很快会被塑料等包装废弃物所包围。
