Tinplate

Tinplate (SPTE, tin-coated iron) is the common name of cold-rolled electroplated tin sheet, which refers to the cold-rolled low-carbon sheet steel or steel strip coated with commercial pure tin on both sides.
Characteristic advantage
1.Light permeability
In addition to triggering deterioration reactions in foods, light also causes changes in proteins and amino acids. The exposure of vitamin C to light makes it easier to interact with other food ingredients, resulting in a large loss. According to research and analysis, the loss of vitamin C in transparent glass bottles of milk is 14 times higher than that in dark bottles of milk, light will also cause milk to produce oxidative smell, as well as nuclide, methionine and other cracking and loss of nutritional value, tinplate can opaque light makes the highest preservation rate of vitamin C.
2.Good sealing
The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. The comparison of various juice packaging containers showed that the oxygen permeability of the container directly affected the Browning and vitamin C preservation of the juice. The preservation of vitamin C is better in metal cans, glass bottles, aluminum foil glue layers and cartons with low oxygen transmission rate, of which iron cans are the best.
3.Reduction of tin
The tin in the inner wall of the tin plate will interact with the oxygen remaining in the container during filling, reducing the chance of the food ingredients being oxidized. The reducing effect of tin has a good preservation effect on the flavor and color of light colored fruits and juices, so the juice cans filled with unpainted iron cans have better nutritional preservation than those filled with other packaging materials, and the Browning change is slight, the acceptance of flavor quality is better, and the storage period is extended.
Use
The application of tinplate is very wide, from as food and beverage packaging materials to grease cans, chemical cans and other miscellaneous cans, the advantages and characteristics of tinplate provide content in the physical and chemical properties of good protection.
