About Ad Tech 650 Freezer Grade Glue Slugs

The Ad Tech 650 is only available in the 1 3/4" glue slug size. The 650 is a flexible, freezer grade packaging hot melt formulated specifically to withstand low temperatures and bond to wax coated boxes. This product is used heavily in the food and produce packaging industries. We recommend applying the 650 glue slugs with the Power Adhesives TEC 3400 glue gun or TEC 6100 glue guns for optimal performance.
