ROHM AND HAAS INTRODUCES A NEW SYNTHETIC COLD SEAL ADHESIVE
Rohm and Haas reports that a synthetic cold seal product is being added to their Coseal line of cold seal adhesives. The new Coseal 55-300 overcomes two major obstacles that have long plagued converters of moisture-sensitive and oxygen-sensitive packaging, such as those used for candy bars, ice cream, or even gummy snacks. The adhesive is being touted as providing a significant improvement in sealing performance for those packaging converters who have relied on natural rubber, while bringing converters who use existing synthetic cold seal adhesives a new, lower priced, higher performance synthetic alternative. The difficulties in mixing natural rubber, a problem that many converters have and one that often leads to unreliable package sealing, is a non-issue with Rohm and Haas' new cold seal product. "Our new Coseal 55-300 is formulated to mix far more easily, quickly, and completely," says John Norder, North American Region business manager for packaging. "It virtually eliminates downstream sealing failures." Even converters who have already adopted a synthetic cold seal adhesive for these applications will benefit from a major cost advantage of the new Coseal synthetic product, says Norder In addition, the product exhibits excellent adhesion to metallized and white OPP films, according to Rohm and Haas North American market manager for packaging and converting, Nancy Smith, who adds, "We believe it will prove to be the best synthetic cold seal product on the market." Smith presented cold seal technology and product-specific data and information recently at the Converting and Package Printing Expo. Now available in North America, the product is fully FDA-certified for direct food contact, has no odors that change taste or aroma, and completely avoids natural rubber, a concern related to allergic reaction in sensitive people. Compared to other synthetic adhesives, the product is said to caulk well, better filling in small gaps during sealing. Rohm and Haas will introduce the product to European converters soon and expects it will be available worldwide in 2006.
