Abstract
An improved method of preventing cohesion between plastic coated, paperboard, folding carton blanks after they come off a die cutter or cutting section of a press. The method comprises providing different scoring patterns for the carton blanks of alternate rows as the cartons are formed, which results in the creation of air spaces between adjacent cartons to prevent them from sticking to each other.
