The PTP 300 (Poly Thru Paper) Sealer is designed to instantly seal polyethylene and foil inner liners used in some flat or gusseted open mouth multi-wall paper bags.  Note…open mouth bags sealed with a PTP closure, still require a primary, external type of closure.  The PTP’s compact, height adjustable pedestal design is fully mobile and can easily be integrated in semi or fully automated bagging applications. Easy and safe to use, the PTP’s variable speed drive operates up to 60 linear feet per minute and features automatic, over temperature shut down, full digital controls and readouts, and standard right to left operation.
