What Westpak does
Westpak (WESTPAK Inc.) is an independent, third-party package and product testing laboratory founded in 1986 and headquartered at 83 Great Oaks Blvd, San Jose, California. The firm operates A2LA-accredited ISO/IEC 17025 testing facilities across three California sites — San Jose, San Diego, and a new 18,500-square-foot Union City laboratory opened in April 2025 — for a total of more than 100,000 square feet of accredited testing space, including 2,600 square feet of ICH-validated stability chambers. Westpak is 100% employee-owned and runs under ISTA certification alongside its ISO 17025 credentials.
The company's core offering is a portfolio of professional testing services organized around reliability testing, package testing, sustainability testing, and specialized protocols (accelerated aging per ASTM F1980-21, container closure integrity, cold chain, dangerous goods packaging, material analysis, and customized testing). Service delivery is anchored in physical testing — calibrated chambers, vibration and shock equipment, and environmental simulation — rather than software. The technical portfolio follows industry-standard methodologies including ASTM D4169, ISTA 3A, and ICH Q1A (R2), addressing regulatory validation needs of medical device and pharmaceutical manufacturers primarily, with secondary exposure to computer electronics, military/aerospace, consumer products, and food/beverage verticals.
Westpak monetizes through project- and per-test-based professional services engagements, with quote-based pricing driven by test complexity, sample quantity, and turnaround time. Customer acquisition is sales-led, consultative, and quote-request-driven, supplemented by content marketing (webinars, white papers, free testing calculators such as Box Compression and ASTM D4169 Vehicle Stacking) and recurring participation as a Premier Sponsor at ISTA's TransPack & TempPack Forum and core-tier exhibitor at MD&M West and MEDevice. A named customer (Centese, medical device) and broad vertical coverage suggest a diversified mid-sized regional testing services business.
