Gel-Pak

What Gel-Pak does

Gel-Pak, founded in 1980 in Hayward, California and operating as a wholly-owned subsidiary of diversified materials company Delphon, designs and manufactures elastomer-based carriers, films, and cleaning materials that protect delicate devices during shipping, handling, and processing. Its technology platform is built on two proprietary elastomer chemistries — silicone Gel and silicone-free Vertec static-dissipative materials — with form factors spanning Gel-Box hinged carriers, Gel-Tray/Gel-Slide pocketless trays, Vacuum Release (VR) trays for automated pick-and-place, Membrane Boxes for irregular 3D objects, BTXF and WPX textured carriers for universal handling, and Gel-Probe sheets/wafers that extend probe card life in semiconductor test operations. The portfolio targets three primary verticals — semiconductor (bare die, wafer, advanced packaging), medical/dental (FDA-compliant biocompatible carriers), and photonics (lenses, FAC lenses, laser diodes) — with secondary exposure to electronics, data storage, and aerospace.

Gel-Pak operates a vertically integrated model spanning in-house polymer formulation, ISO 9001:2015-certified manufacturing across approximately 90,000 sq. ft. of ISO Class 7 and ISO Class 8 cleanroom capacity in Hayward (CA), Wilsonville (OR), and Johor (Malaysia). Revenue is generated predominantly through direct hardware sales of carriers and films, supplemented by custom product development services and recurring Gel-Probe consumables used in semiconductor test. Pricing is quote-based with minimum order quantities typically starting at 100 units; standard quick-turn products are available online with 10-day lead times. Go-to-market is sales-led, combining a North American and International sales team with a global distributor network, supported by deep technical documentation, a Product Selection Wizard, trade-show presence (SWTest, TestConX, IMAPS, Photonics West), and webinars aimed at process engineers and quality teams in target verticals.
