Cold seal

Rohm and Haas has added a new synthetic cold seal product to its Coseal line of cold seal adhesives.


Rohm and Haas‘ new Coseal 55-300 synthetic cold seal adhesive is being touted as providing a significant improvement in sealing performance for packaging companies who have, in the past, relied on natural rubber to seal moisture-sensitive and oxygen-sensitive products such as chocolate bars or ice cream.

“Our new Coseal 55-300 is formulated to mix far more easily, quickly, and completely (than natural rubber),” says John Norder, North American Region business manager for packaging. “It virtually eliminates downstream sealing failures.”


The company adds that its new product also exhibits excellent adhesion to metallised and white OPP films. Now available in North America, the product is fully FDA-certified for direct food contact.


Rohm and Haas will introduce the product to Europe soon and expects it will be available worldwide in 2006.
