Luxury metal round coffee tin supplier--JYB

What is useful life for metal tinplate coffee tin can ?

Dongguan jinyuanbao as a professional coffee tin supplier offer tips for you :

At first , we advise the period of validity during 1 year. The material of the tinplate box is tin-plated sheet steel. Because of the different gold properties of iron and tin, the two metals are easy to produce oxidation reaction under natural conditions, leading to corrosion and rust of the iron sheet. After rust, the tightness of the coffee can is reduced, and it should not be in direct contact with the coffee, which is easy to make the coffee deteriorate.

Secondly , Keep coffee cans in a dry place for later use, as wet places are more likely to rust.

Thirdly , Before coffee tin box is formed, the tinplate will be treated with rust prevention. It is mainly printed with gloss oil. If the outer printing coating is damaged early, it is easy to rust. So not damage outside coating .

As the picture , there are two printing design from our clients ,one is brown and other is green , specially for the coffee packaging . The size of it 105*74mm with large capacity. Not only for coffee , but also for tea/candy/chocolate/biscuit/gift /powder packaging....

Anyway, people can't avoid it when they use it. In many cases, the outer printing will start to fall off under normal circumstances, so it is recommended that the best use time is one year.
