The Reynold’s Seal System utilizes several inserts for different types of films: PVC, Polyethylene, and Polyolefin.
The Wide Fin seal bar contacts with the film across its face. The seal is formed by the heat and pressure of the bar. The cut is made by a thin cutter bar. The result is a seal that can be from 1/8” to 3/16” wide. This type of seal bar works only with shrink films that have been cross linked.
