What MPI Technologies does

MPI Release LLC, doing business as MPI Technologies, is a privately held U.S. specialty manufacturer of customized silicone-coated release liners founded in the 1960s and headquartered in Winchester, Massachusetts, with a second manufacturing facility in Greenfield, Indiana. The company coats paper, film, and specialty substrates with release chemistries tuned to customer-specific adhesives, offering all three industrial silicone curing technologies — Thermal (solvent-based and 100% solids), UV, and Electron Beam — under a single roof. Its asset base includes an 87-inch wide Polytype thermal coater (acquired in 2009), a total of four coaters operating up to three shifts, a 65,000 sq ft warehouse supporting just-in-time programs, and high-speed slitting down to 3-inch widths, with ISO 9001:2008 certified processes and batch-level traceability throughout.

MPI serves four primary vertical end-markets: pressure-sensitive tapes, graphic arts and labels, general industrial composites and building materials, and medical and healthcare devices. The business model is direct B2B with quote-based pricing, combining inside-sales support (1-888-MPI-8088) and a regional field-sales force covering all U.S. states and Canadian provinces. Lead times for most orders are 3–6 weeks, with samples typically returned within 1–2 business days. Revenue is generated through one-off product sales priced on substrate type, coating chemistry, width, and volume, with a Partnership Audit Process offering cost-reduction consulting. MPI participates in PSTC and AIMCAL industry associations and exhibits at Label Expo Americas. The company has 51–100 employees and does not disclose revenue or external investors.

Core offering

MPI develops, engineers, formulates, and manufactures customized silicone-coated release liner products on paper, film, and specialty substrates for industrial customers. The company operates all three silicone curing technologies—Thermal (solvent and 100% solids), UV, and Electron Beam (EB)—with coating widths up to 87 inches and unique two-sided single-pass coating capability. Products are tailored to customer-specified adhesives with release levels ranging from Premium Easy through Ultra Tight, including differential releases.

Product overview

MPI Release LLC is a world-class release liner supplier offering customized silicone coated release liner products. The company provides three primary product lines: Paper Release Liner Substrates (including Super Calendered Kraft, Clay-Coated Papers, Bleached and natural grades, SBS linerboard, and Poly Coated Kraft) and Film Release Liner Substrates (including PET, LDPE, HDPE, PP, and Vinyl/PVC). These substrates are coated with silicone release systems using three curing technologies: Thermal (solvent and 100% solids), UV, and EB (Electron Beam). MPI's release systems are customized for compatibility with customers' specified adhesives, offering release levels from Premium Easy through Ultra Tight, including differential releases. Specialty coatings such as anti-static, traction coating, color tints, and topcoats are available as add-on options.

Broad incumbents

• Felix Schoeller: Felix Schoeller is a German specialty paper manufacturer with a release liner business serving labels, tapes, and composites. It is comparable to MPI as a specialty release liner substrate producer, though primarily European in geographic focus.
• Sappi: Sappi is a global coated paper and release liner producer with significant European and US capacity. Its release liner business overlaps with MPI in coated paper substrates used by tape and label converters, though Sappi is far broader in scope.
• Avery Dennison: Avery Dennison is a global leader in pressure-sensitive labels and adhesive materials, with captive release liner consumption and external release liner products. While not a release liner pure-play, it competes with MPI for label and tape manufacturer supply contracts.
• 3M: 3M is a diversified global manufacturer with a large Industrial Adhesives and Tapes division that consumes significant volumes of release liners. While not a release liner coater, 3M sets technical specifications and quality benchmarks that shape competitive dynamics for suppliers like MPI.
• Ahlstrom: Ahlstrom (formerly Ahlstrom-Munksjö) is a Nordic specialty fiber-based materials manufacturer with release liner products serving tape, label, and industrial markets. It overlaps with MPI in specialty paper-based release liners but spans a much wider filtration and specialty materials portfolio.
• Mondi Group: Mondi is a global paper and packaging group with significant release liner operations, including the acquired Itasa business. It overlaps with MPI in silicone-coated release liners for labels and industrial tapes but operates at much greater scale and across multiple geographies.

Direct peers

• Loparex: Loparex is the world's largest independent manufacturer of silicone release liners, with multiple plants globally and a broad paper and film substrate portfolio. It is the most direct competitor to MPI in custom silicone release liner coating for tapes, labels, medical, and industrial applications.
• Siliconature: Siliconature is an Italian silicone release liner coater offering both thermal and UV/EB curing on paper and film substrates. It is closely comparable to MPI as a specialty release liner coater serving similar customer segments across medical, industrial, and graphics markets.
• Itasa: Itasa is a Spanish release liner manufacturer (now part of the Mondi group) specializing in coated paper release liners for labels and tapes. It is comparable to MPI as a European-headquartered silicone release liner coater with similar substrate range and end-market focus.
• Lintec Corporation: Lintec is a Japanese manufacturer of adhesive products and release liners with operations across Asia, Europe, and the Americas. It directly competes with MPI in silicone-coated paper and film release liners for labels, tapes, and electronic applications.
