Seattle-Tacoma Box

What Seattle-Tacoma Box does

Seattle-Tacoma Box Company is a sixth-generation, family-owned packaging manufacturer founded in 1889 in Seattle and now headquartered in Kent, Washington. The company designs, manufactures, and distributes corrugated, wood, and plastic packaging for agricultural producers, seafood processors, industrial and oil-field customers, consumer goods companies, moving and storage operators, and wine and gift businesses. Its product portfolio includes high-graphic corrugated boxes, traditional wooden boxes, crates, and skids, Modified Atmosphere Packaging (MAP) for shelf-life extension, and polypropylene corrugated packaging marketed as a sustainable alternative to wax boxes.

The company operates from nine owned facilities across Washington, Oregon, Alaska, California, and Arizona, including Commencement Bay Corrugated (a jointly controlled subsidiary formed in 1979 with Pacific Container Corporation), SeaCa Packaging (founded 1991 for Central California agriculture), and SeaCa Plastic Packaging (founded 2014 as the first full-line corrugated polypropylene extrusion plant in the United States). Core manufacturing technology includes a 110-foot Fosber corrugator capable of producing over 2 billion square feet per year, a Mid-5 high-graphic press, flexo folder gluers, rotary die cutters, a cascade waxer, and MAP machinery, supported by in-house structural designers and graphic artists. Certifications include AIB Food Safety Inspection, SFI Chain of Custody, and FDA-approved recycled content for the closed-loop plastics program.

The business model is B2B, quote-based, and sales-led through direct sales representatives working with customers on custom packaging design and prototyping. Revenue is generated from hardware sales of corrugated, wood, MAP, and polypropylene packaging, with all pricing negotiated per project and no public pricing disclosed. The company holds patents in reusable totes and pipe packaging, maintains a New Zealand branch via Trayco Manufacturing, and operates the STB Legacy Foundation established in 2024 for Pacific Northwest community investment. Seattle-Tacoma Box serves customers across the West Coast including Alaska and Hawaii, distinguishing itself from corporate box competitors whose plants are typically limited to a regional radius of a few hundred miles.
