Coldseal Adhesive can be applied in excess of 1,000 fpm

Designed for confectionary, energy bars, ice cream, and other snack food applications, Liofol CS 22-861US1 adheres well to many substrates, including barrier films and surface-treated films for monoweb and laminated structures. Product provides clean wipe, low foam, compatibility with release films and lacquers, and extended shelf life up to 6 months for drums and totes. With Liofol, coating weights are consistent and streaking is virtually eliminated.

Henkel announced the latest addition to the new generation of Liofol laminating adhesives: Liofol CS 22-861US1, which can be applied in excess of 1,000 feet per minute (fpm).

"The high demand for speed and efficiency in food packaging operations prompted our chemists to develop this innovative cold seal coating," said Doug Apicella, Director, Flexible Packaging Marketing, Henkel North America.

Designed for confectionary, energy bars, ice cream, and other snack food applications, this adhesive adheres well to many substrates, including barrier films and surface-treated films for monoweb and laminated structures. In addition, Liofol CS 22-861US1 coldseal coating provides clean wipe, low foam, high bond strength, long shelf life, good shear stability, and compatibility with release films and lacquers.

According to Apicella, the new adhesive has been formulated to further optimize the coldseal coating process by reducing application issues and scrap. "Operators running coldseal coatings at high speeds often face foaming in the pan, coagulation at the blade and build-up on the cylinder," he said. "They are forced to clean up overflow from the pan, or worst yet, to stop the extruder and address those issues. This Liofol adhesive runs at line speeds up to 1,000 fpm without those problems and produces quality finished goods. Coating weights are more consistent and streaking is virtually eliminated. And with an extended shelf life of up to six months for drums and totes, scrap from expired product is minimized."

Liofol CS 22-861US1 has excellent adhesion to substrates such as paper, glassine, cellophane, aluminum and polyester. It is used with heat-seal coated films and barrier films such as acrylic coated OPP and PVDC coated OPP.
