The W4201N can overwrap items in multiple columns and rows that are accumulated and transferred from pre-process. This model designed for pharmaceutical industries based on the experiences of typical carton size, accumulating patterns or packaging processes. Size change for different items to be overwrapped can be completed in just 20 minutes. Since the W4201N is capable of handling a thinner-type film, it reduces the volume of film used and thus helps to reduce costs too.
