2, Metal food cans advantage: Compared with other materials, metal packaging materials are rich in origin. and the production and processing technology has been very mature, manufacturing energy consumption and low cost, can be repeatedly reused. and metal food cans of high strength, ductility and manufacturing process good, coupled with good sealing performance, can meet the packaging requirements.
And the comprehensive protective properties of metal materials, as packaging, from the appearance of looking more upscale, good display, easy to print decoration.
In addition, can also be in the metal food cans surface coating, coating and laminating, so that its performance further improved, prolong the service life.
