Attaining the perfect case and carton seal is a balance of the right hot melt packaging adhesive, the ideal operating parameters and a consistent adhesive pattern. Food and beverage manufacturers rely on hot melt packaging adhesives to assure a strong seal for their products. Unplanned downtime on a packaging line can be significantly reduced when hot melt tanks are filled consistently.

Establishing a routine for filling hot melt tanks will keep the packaging adhesive temperature consistent and prevent char formation, which can lead to plugged filters and nozzles. Issues can arise when a hot melt adhesive tank is:

• Filled inconsistently – results in variable adhesive application temperature and pattern
• Filled below a certain level – known as underfilling, results in overheating the adhesives and char formation
• Filled over a certain level – known as overfilling, increases the potential for dead spots and adhesive waste

LOCTITE^® General Purpose Structural Adhesives, powered by hybrid adhesive technology, are a breakthrough in structural bonding for limitless repair.

Customer Challenges

• A new Programmable Logic Controller (PLC) design required a robust thermal management solution with no outgassing risk.
• As the system can be used in a variety of machines and production environments, the thermal materials must be conducive to many conditions.
• The customer requested the use of a silicone-free thermal solution to avoid silicone contamination, but wanted to maintain the stress control and heat benefits generally consistent with silicone-based thermal interface materials (TIMs).
