H.B. Fuller : Cool alternative to hot melt sealing
H.B. Fuller’s Liquamelt adhesive system (cool until it’s needed, then heat-activated at point of application) now comes with a bulk feed option that eliminates the need for on-floor staff to refill the adhesive reservoir, and a gateway I/O option that allows the system’s operation to be monitored by the packaging machine control system.
The Liquamelt adhesive system delivers up to a 50% improvement in mileage per pound and up to a 50% reduction or more in energy costs compared to traditional hot melt, according to the company. Additional benefits include a non-petroleum formulation based on 40% sustainable raw materials, elimination of heated hoses and related safety concerns, and a formulation composition that helps ensure no char or adhesion to packaging machinery for clean operation and easy cleanup.
The bulk feed capability delivers Liquamelt adhesive in a large container that is replaced when emptied. The bulk delivery option allows containers to be located remotely and the Liquamelt adhesive to be safely transferred from the sealed containers to the packaging machines through common non-heated fluid hoses. Because Liquamelt adhesive is supplied at room temperature and heated just prior to application by the Turboactivator technology located inside the packaging machine, heated transport hoses are not required.
Three bulk container sizes are offered: 30 liter drum, 50 gallon drum, and 2,500 pound tote. These options maintain the Liquamelt system’s cool on delivery –hot on demand operating approach by easily delivering room temperature liquid adhesive from a variety of package options to the Liquamelt application equipment reservoir. Providing a closed, continuous fill operation is important in reducing waste, resulting in lower overall operating costs.
The gateway I/O option enables external communication and provides machine health status. It allows monitoring of the Liquamelt adhesive system by the OEM equipment and helps ensure efficient and reliable line operation.
