<p>A hollow, heat-recoverable article (1), for enclosing objects such as electronic components etc. has a thermoplastic lining on its interior surface and includes a fusion bonded portion (2) in which different parts of the article have been brought together and bonded by fusion of the lining with substantially no welding of the heat-recoverable material forming the wall. The lining has a melting point that is higher than the recovery temperature of the article, thereby enabling subsequent recovery of the article without rupture of the bonded portion.</p> |
