Waldorf Hot Melt Gluability
We use the Waldorf Hot Melt Glue tester to evaluate the gluability of paper and paperboard because it allows very good control of conditions, including glue temperature, open time, and compression time. We use a standard hot melt glue or we use customer’s hot melt glue when it is provided. We use this instrument to evaluate glues on standard paperboard. This instrument can also glue corrugated samples.
