摘　　要：铝是一种绿色环保材料,是一种极佳的制造瓶﹑罐及其他包装器具的材料,具有诸多优点。塑料自问世以来,在作为包装材料方面起了很大的作用,给人们的生活和经济发展带来了很大方便,但是它的最大缺点是可回收再生性差,在自然环境中的降解慢到了不可接受的程度,随着经济的发展,社会上积蓄的废塑料包装品越来越多,造成了严重的环境污染,危及海洋生物安全,近海污染尤为严重,而且塑料产量还在迅速增加。因此必须采取措施用绿色材料取代一部分塑料,铝是当前及未来唯一的这种材料。铝的主要缺点是价格高,但与塑料相比废铝价格还不算高。Aluminum is a kind of green environmental protection material.It is an excellent material with many advantages for making bottles,cans and other packaging utensils.Plastic,as a packaging material,has played a great role since its advent and has brought great convenience to people's life and economic development.However,its biggest disadvantage is poor recyclability,and its degradation in the natural environment is too slow to be acceptable.With the development of economy,more and more waste plastic packaging materials have been accumulated in the society,which has caused serious environmental pollution and endangered the safety of marine life,especially in the offshore area,and the plastic production is increasing rapidly.Therefore,some measures must be taken to replace some plastics with green materials.Aluminum is the only substituted material at present and in the future.The main disadvantage of aluminum is its high price,but compared with plastics,the price of waste aluminum is not so high.
