1.printed tinplate sheet tin has good sealing.
The barrier properties of packaging containers to air and other volatile gases are very important for the preservation of nutritional content and sensory quality. Comparison of various juice packaging containers proves that the oxygen permeability of the container directly affects the browning of the juice and the preservation of vitamin C; the preservation of vitamin C in metal cans, glass bottles, aluminum foil laminates, and cartons with low oxygen permeability Better, of which printed tinplate sheet tin cans are the best.
2.printed tinplate sheet tin has reduction of tin
The tinned inner wall of tinplate interacts with the oxygen remaining in the container during filling, reducing the chance of food ingredients being oxidized. The reduction of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, the use of unpainted tinplate coil cans has better nutritional preservation than other packaging cans, and the brown changes are slight. Acceptability of flavor quality is good, so the shelf life is extended.
3. Tinplate coil has good tensile properties. The tin box made of tinplate coil also has the characteristics of high stamping performance, no aging, and low yield point, so electrolytic tinplate coil has strong stamping characteristics, which can ensure higher precision when cutting the surface of the board.
4, Electrolytic tinplate coil has good printing processing performance. The surface of electrolytic tinplate coil can be printed. Using the physical properties of water and ink, and printing pressure, the printing plate and text are transferred to tinplate coil through a blanket, which belongs to the principle of lithographic offset printing. As a result, the printed tinplate sheet tin box packaging produced is both high-end and beautiful!
