What Vonco Products LLC does

Vonco Products LLC is a privately held US contract manufacturer founded in 1955 (per firmographics; one source cites 1965) and headquartered in Trevor, Wisconsin, with a secondary manufacturing facility in Fortville, Indiana. The company specializes in custom liquid-tight medical fluid bags, single-use medical devices, sterile barrier packaging, and consumer flexible packaging, serving medical device OEMs, biopharma companies, and consumer brands. Core manufacturing capabilities span RF welding, impulse and ultrasonic heat sealing, film lamination, precision converting, and cleanroom assembly across three Class 7 cleanrooms and 40+ converting lines.

The business operates a platform model built on proprietary technology assets: ecoGenesis™ RF welding (enabling PVC-free polymer sealing), LiquaLoc® leak-proof seal technology (backed by a 1-year 100% guarantee), EnteraLoc™ Flow (the company's first FDA 510(k)-cleared branded enteral feeding device, awarded four Flexible Packaging Association Gold Awards in 2022 and granted FDA OTC designation in 2023), and VonSeal® 95kPa biohazard transport bags meeting IATA and DOT requirements. Supporting services include rapid prototyping (solutions in as few as 9 days), design for manufacturability, regulatory and quality support, sterilization management, and the SPARK Innovation Program, which conducts 50+ collaborative sessions annually.

Vonco makes money primarily through enterprise contract manufacturing engagements (quote-based, multi-year) with OEMs, complemented by e-commerce sales of stock products (biohazard bags, vial transport sleeves) at published unit pricing. Revenue is supplemented by design and development services bundled into manufacturing contracts. The company has scaled through three acquisitions — McFarlane Medical (2020), Flex-Pak (2022), and Genesis Plastics Welding (2023) — and operates without disclosed external institutional investment. Customer segments are split roughly 80/20 between Healthcare/Medical Devices (primary) and Consumer Products, with notable long-tenured enterprise relationships exceeding 11 years.
