Henkel launches strong yet energy efficient adhesive

The new technology has been developed to combine the benefits of the company’s Technomelt Supra and Technomelt Cool adhesives.

Jim Sipe, business director, Consumer Packaging, Henkel Adhesive Technologies, Henkel North America, has heralded the reputation of the brand’s Technomelt range in developing an adhesive which provides the "best of both" technologies.

Henkel’s ‘best of both’​

The Supra adhesive is known for its operating window and robust bond strength, according to Sipe. He stated that packagers benefit from increased mileage, clean production, high-quality bonds and reduced maintenance.

The Technomelt Cool adhesive operates 100 degrees Fahrenheit lower than traditional packaging hot melts, which enables a 50 percent reduction of energy consumption, the company claimed.

Like Supra, Cool reduces adhesive consumption by up to 30 percent, cutting the consumption of oil and water used in manufacture and adhesive use.

Sipe said packagers also appreciate the improved safety, non-charring and extended equipment life enabled by Technomelt Cool.

Of the SupraCool hybrid Sipe commented: "It delivers even higher bond strength and wider application range than traditional low temperature technologies while reducing energy consumption, increasing the safety of the end of line operation, and creating an opportunity to improve mileage over either technology."​

SupraCool specifics​

The Technomelt SupraCool has a lower application temperature of 250-275 degrees Fahrenheit, for reduced energy consumption, less equipment wear, and increased safety.

Its application weight is at least 20 percent less than with conventional hot melts. The German-headquartered company claims its heat stability, which eliminates gel and char, reduces maintenance and down time, and promotes uninterrupted production.

According to Sipe, due to a proprietary raw material position for Henkel, the patented SupraCool offers an excellent balance of heat resistance and cold adhesion, as well as excellent adhesion to difficult case and carton stock.

Henkel's Technomelt adhesives are currently used for labels and graphics, as well as paper, tissue and towel converting.
