Rohm and Haas Delivers Packaging Innovation to Pack Expo

October 28, 2008

Innovation excellence with strategic collaboration is the path that specialty materials company Rohm and Haas (NYSE:ROH) intends to follow to maintain leadership in the very competitive flexible packaging adhesives market. The company’s adhesives research and development director, Brad Jacobs, recently detailed several ways Rohm and Haas remains the technology leader by anticipating needs and trends. “For example, customers shipping globally are no longer just a trend but a fact of life,” Jacobs notes. “We now specifically design our high-performance adhesives to provide the necessary international compliance: many of them meet both U.S. FDA and European food packaging regulations while handling the most advanced retort structures that European consumers favor for convenience foods. We’re working with co-suppliers to ensure that our adhesives perform well with emerging sustainable films like those made with cellulose or polylactic acid (PLA),” he comments, adding that the company also is exploring renewable feedstock materials for its packaging adhesives. “Further, we’re working to define exactly how compostability and/or biodegradability will impact the packaging arena.”

At Pack Expo 2008, November 9-13, Rohm and Haas representatives will be discussing these topics with attendees, as well as presenting recent additions to the company’s portfolio. The company’s Pack Expo theme, “Ahead of the Pack,” showcases innovative new offerings that include synthetic cold seals, heat seals for cutting-edge medical packaging, very high performance retort adhesives, solventless choices that solve outgassing in high barrier applications, and a number of waterborne adhesives and barrier innovations. Rohm and Haas recently received a prestigious National Historic Chemical Landmark designation from the American Chemical Society for its acrylic technology, which is widely used in its flexible packaging adhesives.

Rohm and Haas has made significant strides in cold seal technology, which seal with pressure at ambient temperature. “Synthetic cold seal products are red hot in the market right now because they don’t require natural rubber or cause allergy concerns,” says Nancy Smith, North American Region commercial development manager for Packaging Adhesives. “But it’s been hard for customers to find good ones.” Coseal(TM) 55-300, Smith says, handily meets customer and market needs with its revolutionary rubber-latex-free formulation. Employing a proprietary technology, the economical, low-odor product enables very high line speeds for heat-sensitive food packaging and industrial applications. The new product also delivers a desirable even-peel characteristic, good mechanical stability and a tamper-evident mode of failure.

The company’s heat seal technology boasts new offerings for challenging applications ranging from condiments and coffee bags to medical lidding and blister packs. “A new development is our water-based Robond(TM) HS family which will allow converters to dial in the exact porosity necessary for sterilizing medical packaging,” Smith explains. “Furthermore, this new heat seal coating is not sensitive to drying conditions and therefore doesn’t restrict line speeds.” The environmentally advanced product easily endures sterilization methods including gamma radiation and ethylene oxide. Another product in the Robond line laminates increasingly popular clear packaging that allows consumers to visually inspect prospective purchases. “Customers find this adhesive ideal for lidding,” Smith notes, adding that the Robond family accommodates a wide range of activation temperatures to suit equipment requirements and package contents.

For those Pack Expo visitors seeking extremely high-performance adhesives for the latest retort structures, the company’s Adcote(TM) line offers new capabilities. “These products are high-solids, high-performance solvent-borne adhesives,” Smith explains. They succeed in tough laminating situations by resisting aggressive fills, withstanding extreme heat and curing faster to boost process efficiency. Adcote(TM) 842/842D adheres tightly to more challenging clear barrier retortable films frequently found in packaging for microwaveable pre-cooked rice and pasta sauces. Adcote(TM) 250HV-US is a time-proven retort adhesive originally developed for the Japanese market, one with a long history of packaging shelf-stable sauces. Adcote 250HV withstands very aggressive high acid sauces and works well on a wide variety of substrates.

The company’s solventless Mor-Free(TM) line features new products that solve several thorny issues for customers. “Our isocyanate-free Mor-Free 610 solves outgassing problems in industrial applications that can occur with typical solventless adhesives,” Smith relates, adding that such applications produce tough protection for hoses, cables, flexible ducts and sensitive machinery. Smith expects to spend significant time at Pack Expo talking about Mor-Free(TM) L75-164, which delivers exciting new processing efficiencies for general to medium-performance packaging as well as challenging hot-fill applications.

The company’s efforts in water-based technology, further narrowing the performance gap between solvent-based and aqueous laminating adhesives, also signifies its leadership. At Pack Expo, Rohm and Haas representatives will discuss their second generation Robond(TM) L adhesives family for general and medium-performance dry bond applications. “Converters get bond strengths and chemical resistance similar to solvent-based choices – and the adhesive runs on solvent-based equipment, which has been particularly attractive to customers,” Jacobs says, adding that faster line speeds, quicker slitting and the versatility to bond many different substrates are key benefits as well.
