Abstract
A heat-recoverable closure with a crosslinked pressure-sensitive adhesive is provided. The closure member is comprised of a heat-recoverable sheet and a layer of crosslinked pressure-sensitive adhesive, which maintains the closure of the closure member having the recovery process. The combination of a high surface energy heat-recoverable sheet and the crosslinked pressure-sensitive adhesive yield an article having excellent performance as a closure member.
