Tin plated sheet printing has resistance to boiling water and high temperature steam. For food packaging food cans, after printing, physical and chemical performance tests must be carried out according to the sterilization process requirements of the cans, including curing test, acid resistance test, sulfur resistance test, etc. All three tests require the food packaging can body to be placed in different solutions. Heat to 100°C or 120°C for 30 minutes. After the test, the color and gloss of the food can remains unchanged.
Tin sheet printing has processing and molding resistance. After the tin sheet printing ink is dried at high temperature, it must have good mechanical processing properties, including adhesion, flexibility, stamping resistance, etc., to ensure that the ink will not fall off and wear during a series of mechanical processing molding processes.
