For optimal durability, reliability and value, Combi's 2-EZ® HM, and high speed 2-EZ® HS HM and 2-EZ® SB HM case erectors erect corrugated cases and close the bottom flaps with hot melt glue. Equipped with the dependable, industry leading Nordson ProBlue Liberty™ Hot Melt System, glue applied directly to case flaps creates a strong, rigid bond which helps ensure boxes remain intact and the contents secure at all times.
