What Polykap does

Polykap srl is a San Marino-based industrial manufacturer of non-food plastic caps, plugs, and protective components, headquartered at Via dei Paceri 77 in Falciano. Operating for over 25 years from a single facility with 5 production lines, the company maintains a catalog of more than 9,000 standard SKUs covering pressure caps and plugs, threaded caps, plastisol and silicone caps, caps for screws and bolts, and a KAP 300 series of plastic fasteners. Manufacturing relies on materials including PA 6.6, PA 6 with fiberglass, PE-LD, plastisol, silicone, and PET, with a parallel custom-protection service that performs ergonomic study, CAD design, 3D prototyping, and mold construction for series production at no equipment cost to the customer. Warehouse inventory exceeds 18 million pieces, supporting quick-turn fulfillment across European customers.

The company serves a diversified set of industrial verticals — hydraulic components, beverage and keg applications, automotive manufacturing, watchmaking, and earth-moving machinery — alongside a horizontal industrial-manufacturing customer base. Distribution is entirely direct: the multilingual website (English, German, Polish, Italian) accepts contact requests, and segment-dedicated email addresses route inquiries for general, hydraulic, beverage, and automotive inquiries. Specialty products such as the KAP 690 tamper-evident keg seal and the watch-industry protection line indicate domain-specific engineering depth in higher-specification niches.

Since May 2015, Polykap has operated as a subsidiary of US-based Caplugs, a strategic acquirer of protective-component manufacturers. Under this ownership Polykap retains its brand, product portfolio, and direct European sales motion while gaining access to Caplugs' expanded catalog and broader custom-manufacturing capabilities. No public revenue, headcount, or margin figures are disclosed.
