The label manufacturer should be advised that your labels are to be dispensed, and that die cutting is required to be of high standard. Rolls should be wound firmly, but not tightly, and storage areas should be cool, and dry. Labels should be preferably stored in a polybag or plastic bag, and usually have a shelf life of 2 years. Give consideration when ordering as to label placement on the web, so that the label reaches the operator's hand with no need for further orientation. A good dispenser design will compensate for poorly produced labels to a large degree.
Good labels are essential for ideal dispenser performance.
As with any work action involving some operator skill, a learning curve is to be expected with any new dispenser. It is certain, that a properly designed and adjusted label dispenser will give highly cost effective performance, and will reduce tedium and improve productivity in your factory, office, or warehouse.
