摘　　要：铝是地壳中储量最丰富的金属元素,又具有诸多优秀的性能,是一种最为理想的可用于食品及其他产品包装的金属材料。2006年,全世界铝的消费量约50000kt,其中原铝33970kt(此为产量,可视为表观消费量),用于包装工业的约占18.5%。在2015年以前,包装工业用铝的表观消费量的年平均增长率可达4.2%。2006年中国对铝罐、瓶、桶的需求量为366kt,今后8年对其需求量的年平均增长率约10%;对双零包装箔的需求为105.5kt,2015年的为380kt。罐料厚度已减薄至0.24mm,看来再减薄的可能性不大,食品包装箔的最薄厚度在现有技术条件下为0.006mm。中国已成为世界包装双零箔初级强国。铝对人体是安全的。Aluminium is the most metallic element in crust. It has many perfect performances, and is a most idealized kind of metal meterials used for foods and other packing. The consumption of aluminum was about 50 000 kt in the world in 2006. The primary alu- minum was 33 970 kt（this was the production,can be as apparent consumption）.Among them, 15.5% were used in the packing in- dustry. Before 2015,the annual over increasing rate of the aluminum apparent consumption in packing industry can be reached to 4.2%. The requirements of aluminum cans, bottles, tubes were 366 kt in China in 2006. The annual over increasing rate of the alu- minum requirements will be about 10% in the next 8 years.The requirement of the packing foil with double zero will be 105.5 kt, it will be 380 kt in 2015 .The thickness of car material is reduced to 0.24 mm now,and we have less possibility of reducing it.The most thickness of the foods packing foil is 0.006 mm under the existing technical conditions. China has been the primary stronger state of the packing foil with double zero in the world. Aluminum is soft for the human body.
