Sealing performance of tinplate packaging

Sealing performance of tinplate packaging

The barrier properties of tinplate packaging containers to air and other volatile gases are very important for the preservation of nutrients and sensory quality. Comparison of various juice packaging containers proves that the oxygen transmission rate of the container directly affects the browning of juice and the preservation of vitamin C; metal cans, glass bottles, aluminum foil laminates, and cartons with low oxygen transmission rate can preserve vitamin C It is better, and among them, the iron can is the best. The barrier properties of the tinplate box to the outside air are very important for the internal nutrients and sensory preservation of the food. The low gas permeability in the tin box can better protect the food from external pollution and influence. Makes food safe and healthy.
