New from Rohm and Haas is the Robond L range of water based, dry bond laminating adhesives. Developed to meet general and medium performance applications for a broad range of packaging laminations, this patented technology is said to offer bond strength and chemical resistance typical of solvent adhesives, with excellent laminating performance - even on CPP films and laminate constructions with aluminum foil. Greater bond strength, chemical resistance to filled products, as well the ability to operate at faster line speeds, often using the same product for multiple packaging requirements, are promised.
Suitable for use with films, foils, and paper, the laminations are also said to endure pasteurization and aggressive filling goods, such as flavoured coffee or sauces. Rohm and Haas reports that customers who have beta tested the new adhesives found the lower coat weights and high running speeds did not cause foaming or anilox roller clogging, problems associated with earlier water based products. The ability to run on existing solvent based equipment is expected to be an especially appealing operating attribute.
