What Mills Industries does

Mills Industries is a fourth-generation, family-owned manufacturer of custom corrugated plastic packaging, founded in 1947 and operating today from a single facility in Laconia, New Hampshire. The company designs and produces containers, trays, totes, partitions, dividers, collapsible cartons, and cleanroom packaging using profile-extruded fluted co-polymer material in wall thicknesses from 2mm to 10mm, anchored by two proprietary processes — Milform® (6-10mm wall industrial containers with superior durability) and Milseal® (heat-sealed edges that eliminate exposed fluting). Supporting in-house capabilities include CAD-based engineering and prototyping (AutoCAD, Fusion, Artios) on an 85 x 120 inch CNC table, precision die cutting, and screen printing for branding and labeling. The company also holds ISO 9001:2015 certification and operates its facility on wind power since 2009.

The business serves six primary customer verticals — industrial/material handling, life sciences and medical (cleanroom, pharmaceutical, biomedical), aerospace and defense, automotive, retail display and marketing, and fulfillment and distribution — through a direct B2B sales model driven by website quote requests and custom-engineered solutions. Revenue is generated through one-time sales of custom-manufactured products supplemented by professional services revenue from engineering/prototyping, die cutting, and screen printing engagements. Pricing is quote-based with a 50-piece minimum order quantity and material/color customization options; the company notes multi-year contracts as the typical billing cadence, though specific pricing is not publicly disclosed.

The company is privately held with no institutional investment, has 1-10 employees per its profile, and operates exclusively in the United States with a stated focus on the New England market. Ownership and operational leadership remain concentrated within the Mills family across four generations, with current president Michael Mills representing the third generation. No subsidiaries, funding rounds, acquisitions, or geographic expansions are documented, and revenue is not publicly disclosed.
