The Acme M Seal is a plastic pull tight seal manufactured from Polypropylene material and has been introduced as a direct replacement for the tried and tested Minitight that has now withdrawn from our product portfolio. The locking action is very similar to the old Minitight but has the contours of the smooth X Seal.


The new design M Seal offers a cost effective solution for applications where strength is not the primary requirement, but is ideal for use as an indicative seal.
