Another problem has arisen where polymer 'jelly' stamps are being sold to the craft industry, these polymer stamps have no structural backing allowing the polymer stamp to adhere to an acrylic block without adhesives. In theory this works well, the problem is that distortion of the stamp can occur as well as the possibility that the stamp can tear.
Thankfully a new clear silicone based product called InstaGrip has solved this problem so a polymer stamp with a sound structural backing can be adhered in the same way, without adhesive.

So where is the industry heading?
Business stamping seems to be just as strong as it always has been, with the introduction of the bagged polymer many more manufacturers will be offering polymer stamps due to the bag's labour saving benefits and the lower entry cost for polymer processing equipment.
The craft stamp industry will see much more polymer in the future for much the same reasons. The demand for custom made stamps through services such as stampsearch.com.au here you select craft artwork online and then have that image made into a stamp will help the polymer stamp industry develop in a positive manner.
