Avery Dennison DOL 3100 is an 80 micron matt polymeric calendered overlaminate. The DOL 3100 is designed to provide an increase in UV protection and longevity for the printed media. DOL 3100 is a perfect match to any of the media in the Avery Dennison MPI 3000 range. The DOL 3100 is suitable for both internal and external application and can be applied over flat surfaces. The rule of thumb is the overlaminate must match or exceed the life of the media.
