With MMDV Extrusion Valve, water-based cohesive can be applied quickly with exact intermission cycles, forming chemical bond with package surfaces that holds firm until it is time to unstack pallets. Cohesive is stronger than stretch wrap alone and is cold applied making it safer than hot melt. It does not leave sticky residue or harm packaging surfaces. Since MMDV Valve can be used with very low pressures, it accommodates most plant air capabilities.
