ATMI Announces BrightPak(TM) Technology for Advanced Performance in Critical Liquid Materials Containment and Delivery

ATMI, Inc. (Nasdaq:ATMI) announced a new innovation in critical materials packaging today with the introduction of BrightPak™, its next-generation liquid containment and delivery system. Introduced to address the requirements of advanced photolithography, BrightPak systems are designed to deliver significant benefits and increased performance in system integrity, efficiency, optimized cost-of-ownership and safety, versus traditional systems and glass bottles.

Commercial opportunities for BrightPak systems include current and prospective ATMI customers performing high-value liquid material transfers into process steps, including those in the semiconductor, flat panel display and LED markets. Additional markets and applications may include biopharmaceutical, solar panel manufacturing and the application of adhesives.

"ATMI has been the market and technology leader in liquid packaging for the semiconductor lithography segment for a long time," noted Chris Kramer, ATMI's senior vice president of materials solutions. "Today, we look to continue that leadership with our next-generation packaging solution. BrightPak technology is an innovation that reduces customer risk and delivers improved safety and performance. Simply stated, BrightPak systems are safer, cleaner, better."

Advanced Design, Increased Benefits

BrightPak bottle systems are created first as a small plastic pre-form that includes both an external overpack and an internal 'hard' or rigid liner. It is then blow-molded into a larger bottle form with a capacity of just under five liters. The final product is a double-containment bottle system with a rigid, yet collapsible, interior liner. With its advanced design, the BrightPak bottle system offers approximately 21% additional volume compared to the typical one-gallon glass bottle used in lithography applications today. In fact, BrightPak bottles allow this higher fill volume without impacting the customer's labeling surface, the handle location or the physical dimension of the chemical cabinet.

From filling and shipping to storing and dispensing, the system's double-containment design and materials of construction deliver exceptional chemical protection from environmental factors, as well as accidents and operator errors. Unlike glass bottles, BrightPak bottles are made from shatterproof materials and will not easily break if dropped, especially when filled. The ergonomic design of the bottle and handle allows for easy and safe operator handling. The bottle shape, connectors and diptube were designed together for superior material delivery with an optimum utilization.

"We are offering the industry much-improved benefits with our new BrightPak systems and we're working to make the transition as easy as possible," commented Garth Su, ATMI's senior director of the packaging business group and global product marketing. "All BrightPak systems work with connectors for widely-used glass bottle systems, as well as existing ATMI connectors and caps. Of course, that includes our misconnect prevention capability to eliminate human connection errors."

High-Purity, Flexible and Cost Effective

BrightPak systems are cleanroom-manufactured, particle certified and provide superior chemical protection from UV light exposure. Moreover, the wetted surface is made of high-purity, chemical-resistant materials. BrightPak systems also offer improved flexibility for customers looking for both pump-enabled and pressure-dispense solutions. The rigid, collapsible liner provides improved isolation of drive gas when pressure is applied between the liner and overpack. This creates a safer environment for the materials that can help reduce the formation of micro-bubbles and other defects. BrightPak systems are also cost-effective, providing utilization rates of up to 99.9% of filled product which minimizes product waste. In addition, the system's small footprint can help free-up facility space and its light weight can reduce shipping costs. BrightPak overpacks are recyclable and the interior rigid liners are more disposable-friendly, yielding a much smaller carbon footprint than glass bottles.
