What Rennco does

Rennco is a US-based manufacturer of vertical bagging machinery, L-bar sealers, and medical heat sealing equipment, founded in 1969 and headquartered in Homer, Michigan. Operating as a product brand within ProMach's Flexibles business line, the company's core technology is a proprietary continuously heated coated seal bar assembly that seals polyethylene and polyolefin films without requiring part changes when switching film types. The product portfolio spans five categories: e-commerce packaging systems (ProCommerce Bubble Bagging, 301 E-Commerce Bagging System, EZ20 Vertical Bagger), food service disposable automation (VCCL and Micro VCCL cup counters, lid/plate/tray packaging, trim press interfacing), commercial laundry bagging (ProPick hands-free towel system, Weigh Bagger, Little Buddy Bagger), semi-automatic L-bar sealers (Models 201, 301, 501 and their Pouch Pack variants plus EZ Bagger Infeeds), and medical device heat sealing (Lift Seal 18 LS and 24 LS).

Rennco generates revenue primarily through quote-based capital equipment sales, supported by aftermarket parts, service contracts, and machine upgrade retrofits (seal system modernizations, HMI/PLC technology upgrades, safety retrofits). Commercial reach is delivered via a regional direct field sales organization with dedicated US and European coverage, complemented by participation in PACK EXPO International, an extensive YouTube demonstration library, and the parent ProMach's global distribution network across North America, Latin America, the Middle East, and Asia. Integration partnerships with AUBO Robotics (cobotic infeed), ID Technology (print-and-apply labeling), and sibling ProMach brand Edson Packaging extend solution scope beyond standalone machines.

End-markets are diversified across e-commerce fulfillment, paper cup and food service disposable manufacturing, commercial laundry operations, and medical device sterile packaging. Named case studies span contract packaging, commercial laundering, and disposable cup manufacturing. In May 2025, parent ProMach acquired DJS Systems — a 70+ employee disposable food service packaging automation specialist also based in Homer, Michigan — consolidating complementary food-service disposable capabilities under Rennco's operations and adding precision counting, thermoforming, and vertical bagging capacity to the unit.
