1. Most spte tinplate material boxes use 0.23mm tin-plated tinplate products, and the function of tin-plating is that tin has a reducing effect. The tin on the inner wall of the tinplate will interact with the oxygen remaining in the tin can during filling, reducing the chance of food being oxidized. The reduction effect of tin is more aimed at the preservation effect of canned food such as canned fruit and juice, which prolongs the storage period of food.
2. In addition to the deterioration of food, light will also cause changes in protein and amino acids in food, and vitamin C in food will be greatly disadvantaged after being irradiated by pipeline, and the light-proof performance of spte tinplate material can effectively preserve vitamin C.
3. Compared with plastic, glass, wood, paper and other packaging materials, tinplate products have high strength, good rigidity, and are not easy to break. Not only tinplate products can be used for small sales packaging, but also the main container for large transport packaging.
4. The technology of the lacquered tinplate box is mature and the production efficiency is high. Tinplate cans have survived in my country for more than 30 years. The technology is mature and there are matching production equipment. The production efficiency is high and can meet the packaging needs of various products.
