Benefits of Using Low Temperature Hot Melt: Case and Carton

So what are the benefits of using low temperature hot melt?

Improved Stability: The reduction in application temperature provides a substantial decrease in the thermal degradation of the adhesive.  This will provide greater consistency from the adhesive, both in application characteristics and adhesive performance.

Reduced Downtime: Hot Melts tend to char over time at elevated temperatures resulting in plugged nozzles.  Productivity is lost when production lines have to be shut down to replace or repair these nozzles.  The low temp adhesive, due to its lower application temperature and improved stability, will reduce the amount of char generated in an adhesive application system and improve efficiencies.

Reduced Maintenance Cost: Hot melt application equipment can be expensive to maintain.  A temperature reduction of approximately 100°F will reduce the wear on pumps and hoses in the adhesive application system and will result in fewer nozzles being replaced due to damage caused by cleaning and handling.

Safety: Although the adhesive is still hot enough to cause burns, the potential for severe burns is reduced with low application temperature hot melts.  Not only is the adhesive applied cooler than traditional hot melts but the associated nozzles, fittings and hoses are cooler as well.

Low Odor: The VOC (Volatile Organic Compounds) associated with hot melts are reduced by the lower application temperature.  Although these VOC’s are not considered to be hazardous, they do contribute to the odor associated with hot melt adhesives.

Efficiency: The fast set speeds of the low temp adhesive has allowed customers to improve line speeds by as much as 30%.  This increase in productivity has even been documented in applications where the incumbent adhesive touted a 1 second set time.

Reduced Energy Consumption: Since the adhesive is applied at 250°F to 270°F, the amount of energy required to heat and maintain this adhesive at application temperature is reduced, as compared with traditional 350°F Hot Melts.
