Tri-Seal International, Inc.

Tri-Seal International, Inc. is a Blauvelt, New York-based company that is a leader in the design and manufacture of sophisticated thermoplastic extruded and co-extruded capliners and seals marketed under the Tri-Seal, Tri-Gard and Tri-Shield trademarks, among other. It is one of the largest independent manufacturers of closure liners in the US and is a recognized leader of such products in the food, beverage, pharmaceutical, medical, cosmetic, household and industrial chemical, automotive, marine and electronic industries. 

The Company’s high-quality, patented cap liners are used in either plastic or metal closures to form a seal to prevent leakage, evaporation, or product tampering. Tri-Seal’s liners are an essential element in the packaging of many household, consumer and industrial products such as Clorox, Wisk, Windex, and Tropicana.

The Company’s name originated from a patented, triple-layer sealing process that can be adapted for a wide range of packaging applications. Tri-Seal’s original patented closure liner product, named Tri-Seal F-217, is an industry standard for sealing products ranging from corrosive acids to beverages. The seal is a co-extruded structure of low-density polyethylene foam core sandwiched between two layers of LDPE film.

Tri-Seal was acquired in January 1999 by a wholly-owned subsidiary of Tekni-Plex. Tekni-Plex, Inc. is a global, diversified manufacturer of packaging products and materials for the healthcare, consumer, and food packaging industries. Tekni-Plex is a privately held company, with 28 manufacturing facilities worldwide and approximately 2,800 employees.

Tri-Seal President and Chief Operating Officer Bruce Burns added that "as part of a well capitalized, forward looking company like Tekni-Plex, we can offer customers a growing international presence in both manufacturing and marketing. This technology-driven parent will further enhance Tri-Seal’s ability to deliver the most advanced products in the industry.

Tekni-Plex Chairman and Chief Executive Officer, Dr. F. Patrick Smith, stated that "this acquisition will dramatically extend our product offerings in the closure liner industry. Tri-Seal adds highly complementary technology to our traditional laminated closure liner business, as well as our dispenser gasket product lines. In fact, our European operations have been a licensee of Tri-Seal technology for years. Another significant benefit will be the addition of experienced Tri-Seal managers, who will play a key role in operating the combined cap-lining materials business. Simply put, this is a great fit."
