-Water based organic cohesive provides greater load containment while reducing waste-

Arlington Heights, IL (May 26, 2015)
– Lock N’ Pop™, a premier load containment solution provider from Muller LCS and part of SIG, introduces a new MMDV extrusion valve for its water-based cohesive which forms a chemical bond with package surfaces that holds firm until it’s time to un-stack the pallets. With increased demand, greater automation and changing load types, the MMDV valve allows Lock N’ Pop’s cohesive to be applied very quickly with exact intermission cycles.

The MMDV valve helps clients achieve even greater savings by now allowing applications with very small dimensions and low space requirements to incorporate Lock N’ Pop without product waste or fear of incorporating new equipment. The MMDV series extrusion valve can be used with very low pressures which accommodates most plant air capabilities

“We are continuously looking for ways to improve our solution offerings,” says Rosanna Cavanaugh, Business Manager, Lock N’ Pop and Lachenmeier NA. “The new valve offering is another example of that commitment.”

Lock N’ Pop’s water-based cohesive is stronger than stretch wrap alone and is cold applied making it safer than hot melt. It does not leave a sticky residue or harm packaging surfaces when unstacking/popping product apart.  Lock N’ Pop further allows for heavy reductions in traditional packaging-- stretch film, slip sheets, dunnage bags, corner boards and more can be virtually eliminated while maintaining proper load security.

“With Lock N’Pop many of our customers are able to save over 50% in film use alone,” says Cavanaugh. “Last year we were able to help clients collectively eliminate over 10 million pounds of film.”

Lock N’ Pop cohesive can be applied with or without Lock N’ Pop equipment-which is compact, inexpensive, and virtually maintenance free. Unlike solvent or latex based materials that may be hazardous or difficult to clean and maintain, Lock N’ Pop solutions are completely water-soluble, and require minimal maintenance on application equipment. Formulated with FDA approved ingredients, the cohesive can be applied to ambient as well as refrigerated or frozen goods.
