Packaging machine and method for paperboard cartons

Abstract

A packaging system and device for paperboard cartons having closure flaps which extend across and seal the carton opening when filled with articles. The flaps, which are prone to distortion, are treated with a minor amount of water which reverses the distortion and allows the articles to be successfully inserted through the opening and into the carton.
