1/2″ Closed Seals for Polypropylene Strapping

The 1/2” Closed seals need to be threaded on before the strapping is applied, therefore not making them as time efficient as open seals. The advantage to closed seals are the ability to help keep the plastic strapping in line when applying tension. Once tension is applied to the strapping, the closed seal is easily pushed closed to seal the strapping.
