Plastic Bag Manufacturer With a Climbing Static Problem

A few months ago I received a call from Medipak.  After discussing their application they were kind enough to take advantage of our giveaway (Link Here) by sending us some pictures and an explanation of their application utilizing our Super Ion Air Knives.   Medipak manufactures special UVLI bags that are processed on a machine that was designed to do so.   These bags start on a roll then they are pulled through a machine which cuts and sorts them.  A picture of the machine is below.

The problem Medipak experienced was the feed would lose tension which would allow the bag to start to climb up the curtain which applied tension to the feed.  This would cause considerable amounts of downtime as it was happening quite frequently.   After discussing the application, the customer sent these pictures of the problem he was seeing.   Note the system had a “Static Eliminator” on the cutting end of the machine that would not help with any of the problems he was actually seeing.

Another issue they encountered was when the machine would start to really build up a static charge the bag lengths would start to become erratic and out of spec.

The solution to these issues was to install a Super Ion Air Knife.  The unit mounted quite easily utilizing our Universal Air Knife Mounting System.

Medipak has since seen the bulk material climbing the tension curtain come to a halt along with the problem at the cutting end because the Super Ion Air Knife eliminated all issues with the bag feeding errors and incorrect cutting.

If you’ve had an experience like this customer feel free to send us pictures, video, or even a well written description of your application and you’ll be entered into our giveaway.
