What is the material of Wang Laoji's cans? Aluminum?

Compared with other packaging containers, aluminum cans are more environmentally friendly. As far as their containers are concerned, repeated recycling can reduce environmental pollution. As far as the materials used are concerned, repeated use of aluminum can effectively save resources and maintain the global environment.

Extended data

The tin in the inner wall of the can will react with the residual oxygen in the container during filling, reducing the chance of oxidation of food components. The reduction of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, compared with fruit juice cans packed with other packaging materials, fruit juice cans packed with unpainted iron have better nutrition preservation, slight browning, better acceptability of flavor quality and longer shelf life.

In addition, these tanks provide a closed system, which is completely isolated from environmental factors except heat. Color-avoiding foods are deteriorated by light, oxygen and humidity, and are not weakened by aroma or changed by environmental odor. The storage stability of food is better than other packaging materials, with the highest preservation rate of vitamin C and the best preservation of nutrients.
