Abstract
A collapsible metal tube, comprising: a metal body portion susceptible of plastic deformation, the body portion being sealed at one end; a shoulder portion and a mouth/neck portion connected to the other end of the body portion; and a resin film provided on the inside wall surface of the body portion, the resin film comprising a metal-adhesive thermoplastic resin layer formed by spray-coating the inside wall surface of the body portion with a dispersion of fine spherical particles consisting of a metal-adhesive thermoplastic resin and then heating to integrate the particles. The resin film formed on the inside of the collapsible metal tube is reliable because it is a dense resin film virtually devoid of pinholes, excellent in elongation at break, and free from cracking when folded or deformed, and is excellent in ability of protecting the metal body portion and the contents.
