The M Seal is a pull tight seal manufactured from Polypropylene material and has been introduced as a direct replacement for the tried and tested Mini-tight that has now withdrawn from our product portfolio. The locking action is very similar to the old Mini-tight 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.
