ABSTRACT:
A method for preventing bulges in liquid packaging. Disclosed is a mechanical process for squeezing the carton during the carton sealing process. When sealed, a partial vacuum is created, thus making the filled and sealed carton side walls concave. Over an extended period of time, the vacuum will release to the point of having a straight wall carton.
