New Resin-Film Laminated Steel Sheet for 18l Cans and Pail Cans 'UNIVERSAL BRITE~®' Type E

摘要

JFE Steel developed and commercialized a resin-film laminated steel sheet called "UNIVERSAL BRITE~®" Type E which is applicable to large cans such as 18 l cans and pail cans using a newly-developed 2-layer polypropylene (PP) film. In the main layer, the requirements of flexibility and heat resistance are both satisfied by using block PP, while good adhesion with the steel sheet is secured by an adhesive sublayer consisting of carboxylic acid-modified PP with carboxylic acid-modified polyethylene (PE) added in the optimum ratio. As a result, the new laminated steel sheet is suitable for a wide range of contents, including surfactants. The new sheet also features designability by lacquer painting, as its heat resistance prevents film melting due to the heat of baking when a lacquer coating is applied to the outer side of the can. JFE Steel has also developed a new lineup of polyethylene terephthalate (PET)-laminated steel sheets which respond to a wide variety of customer needs in the field of large cans, including an inside PET-laminated steel sheet for food containers which do not require alkaline resistance and an outside PET-laminated sheet for paint and solvent cans without an inside coating.
