PVC vinyl sandblast tape

What exactly is a PVC (vinyl) sandblast tape? Oddly enough there are several types of tape in the market that can get labelled as a “sandblast tape”. In this post we are going to explain about the one used as a protection from sandblasting during the engraving or etching process for tombstones, plaques gravestones. There are other products that are decorative and used to give glass a milky appearance, but these are not the focus of this post.

The tape comes in roughly 500mm to 650mm widths and is typically grey or blue in colour, although other colours exist too. The material is a thick coloured PVC that is tough enough to withstand the high powered shot of sand that is blown on to it during the engraving process. Typically thickness is around 250 to 300 microns.

The tape has a silicon paper backing (release liner) which is necessary to protect the adhesive surface during the cutting of the stencil on the vinyl plotter or cutter.

The adhesive is carefully balanced to allow sufficient adhesion to the stone surface during the sandblasting process and yet also allows for clean removal of the inner stencil parts and after the sandblasting process is complete.

This sandblast tape is typically used by funeral parlours, tombstone manufacturers and stone plaque manufacturers.
