摘要

Metal cans offer affordable long-term storage for a wide range of foodstuffs, and coatings play an intrinsic protective role, inside and out.Protective internal coatings for beverages and solid foodstuffs have for decades been based on a relatively small number of basic chemistries for regulatory and performance reasons, according to Metal Packaging Manufacturers Association (MPMA) technical manager David Smith.Smith says: "Epoxy-based internal coatings have been the mainstay for use in contact with both food and beverage products for decades because of their workability, substrate adhesion, product resistance and freedom from taint qualities."One way to improve the perception of coated metal packaging for the future could lie in the formulation of 'cleaner' coatings. Smith says this doesn't mean coatings haven't always been clean: "It has to be stressed that 'traditional' coatings have been 'clean' in the regulatory and consumer safety senses, but even cleaner coatings could raise the image of metal packaging onto a higher plane."
