ABSTRACT:
A method wherein a machine-foldable wrapper for chewing gum has a paper substrate metallized to give the appearance of continuous foil, the foil being made discontinuous to allow the paper to reach and maintain a moisture content which is in equilibrium with the ambient air. This prevents the wrapper from curling at the edges while in storage.
