Food tin can manufacturers:What is the difference between miscellaneous cans and liquid tinplate cans? The different reasons are as follows:
1. The sealing properties of miscellaneous cans and liquid tinplate cans are different
Milk powder cans, oil cans and beverage cans have very strict requirements on the tightness of iron cans. They are usually easy-pull cans or pull-welded cans. The process is that the can body is connected by a welding process, and its sealing is good. The tinplate cans are also called miscellaneous cans. The connection of the can body is made by pressing the button bone process, so the sealing is poor. Not only that, the leakage of liquid and powder will also occur when the powder is directly loaded. Moisture deterioration will occur over time.
2. The production environment of miscellaneous cans and liquid tinplate cans is different
Since beverages, oils and powders are directly packed into cans, it requires a relatively clean production environment. It requires disinfection equipment and dust-free workshops to meet the safety requirements of direct food contact with tinplate cans. The production environment of ordinary tinplate cans is relatively simple, and the produced cans are simply wiped.
