What Polysec does

Polysec (Polyec Kalıplama, Plastik ve Güvenlik Mühürleri Ltd. Şti.) is a privately held Turkish industrial manufacturer founded in 2021 and headquartered in the Eyüp district of Istanbul, with 51-100 employees. The company operates across three integrated lines: patented plastic security seals (the PLS series covering high-end steel-wire seals through single-piece plastic seals), plastic injection molding for industrial modules, and plastic mold design and manufacturing. Its cooling group equipment modules for cooling towers and wastewater treatment plants position it as the first and largest domestic manufacturer in that niche, while its security seals serve meter sealing (electricity, water, natural gas, oil), logistics containers, customs bonded warehouses, and high-security government and defense use cases.

Core technology centers on proprietary one-way lock capsule mechanisms with fully enclosed steel wire and steel springs, ultrasonic-welded polycarbonate assemblies rated from +90°C to -40°C, and RFID-integrated smart seal modules that convert physical seals into data-tracking assets with optional barcode, laser marking, hologram, and latentogram authentication. Production is managed end-to-end through a four-stage process of project planning, design and 3D modeling, molding and injection, and renovation, with R&D supported by university collaborations. The company holds ISO 9001, 14001, and 45001 certifications, a Yerli Malı Belgesi local-content certificate, the Polysec® trademark, and security seal patents.

Polysec's business model is a sales-led direct industrial model: it designs, manufactures, and ships hardware (security seals, seal wire, security labels, cooling/wastewater modules) directly to enterprise customers, supplemented by industrial consulting and project design services covering RFID seal software, plastics, molding, and injection cost/time management. Pricing is not publicly disclosed and is quote-based. Revenue streams span hardware sales (security seals, plastic injection products) and professional services (industrial consulting, project design, plastic molding). The company sells across Turkey, the United Kingdom, Germany, France, the Middle East, and South America via direct enterprise sales, wholesale/distributor channels for seal wire, and a multi-language corporate website (TR/EN/FR/ES), with a marketing presence on LinkedIn, Instagram, Facebook, and YouTube and a demo-product evaluation program for prospective customers.
