Abstract

A cigarette or other tobacco product package may be constructed with a sealed outer overwrap. The overwrap may be multi-layered and configured to contain an internal pressure higher than an ambient external air pressure. The multilayer overwrap may be assembled to a cigarette or other tobacco product pack in two or more layers adhered together during assembly.
