It is estimated that the sales of iron packaging in the world will increase from 16 million tons in 2005 to 20 million tons in 2010, with an annual growth rate of 8%, of which the growth in Asia will reach 48% of the world demand growth. Asia’s population will exceed 4 billion by 2010, accounting for 60.4% of the world’s population. The per capita consumption of iron packaging in Asia is 1.5kg, compared with 8.4kg in the United States and 6.9kg in Europe. Therefore, the development of iron packaging in Asia will definitely have considerable space in the future.
There will be two main changes in the iron packaging industry in the future: one is that in developing countries there is a shortage of food products due to population growth, so the demand for food production and transportation safety will be higher and higher; the other is It is because of the changes in people’s lifestyles in these countries that the packaging requirements for food are convenient to meet the needs of the new consumer market. In addition, the cost of recycling and disposal of iron packaging is low, which is conducive to recycling.
From an environmental point of view, human consumption of iron can be evaluated by energy consumption and carbon dioxide pollution. Compared with other packaging materials, the food in iron packaging has the least pollution to the hands of consumers, the performance of the packaging is stable, and the design has visual effects.
In order to develop iron packaging, the can industry has made a lot of innovations, such as coffee cans that can be sealed multiple times, the design of the convex pattern of the can body, the technology of expanding the can, the development of the easy-open lid with low breaking force, and the application of the tear-off lid technology , Thin iron deep-drawn cans to meet the preferences of consumers at different levels and reduce the loss of nutrients in canned food.
