Organic Acid Resistance Improvement in Polymer Coated Metals

摘要

A method to inhibit the attack by organic acid such as acetic acid, of a thermoplastic polymer coated on a metal container body and/or end. The method includes flash heat treating the whole respective polymer coated metal parts of the container intended to come into contact with the organic acid such that the polymer on the parts is heated to above its melting temperature to make the container suitable for packaging organic acid-containing contents.
