Troubleshooting Tips & Tricks*

Problem Possible Cause & Solution

My Labels Do Not Stick to the Bag!

(Applies to JSL Header Jaw Sealer Labeler)

Bags used with the JSL should be made of Cellophane or Polypropylene.  Labels will not adhere to plain polypropylene.  Therefore, polypropylene bags should have a coating, such as saran, that provides a bonding surface to which the label will stick when heat and pressure are applied by the JSL's sealing jaw.
