Abstract
Polyvinyl alcohol (PVOH) is used as a slip coating on a cigarette package innerwrap to prevent the innerwrap from sticking to the rollers of cigarette packaging machinery during processing of the innerwrap material. PVOH unexpectedly has a low retention of menthol, as compared to conventional slip coating materials, which also makes it useful in mentholation processes that involve applying menthol to the innerwrap rather than to the cigarettes per se.
