In today’s food processing environment, maintaining sanitary conditions and regulatory compliance while maximizing operational uptime is critical. Food‑grade seals are more than components — they are the frontline defense against contamination, leaks, and production downtime. Hanna Rubber delivers high-quality, FDA/NSF‑compliant sealing solutions designed specifically for the food industry’s safety, sanitation, and performance needs.
The Challenge: Food‑Industry Sealing Requirements
Food processing equipment operates under rigorous conditions: high and low temperatures, steam cleaning, aggressive sanitizing chemicals, oil and fat exposure, and frequent disassembly for cleaning. Seals and gaskets in these systems must maintain integrity without contaminating food products, resisting bacteria growth, and complying with strict regulations. Using non‑certified or standard industrial seals can lead to leaks, flavor contamination, regulatory failures, or costly recalls.
Hanna Rubber’s Food‑Grade Sealing Solutions
Hanna Rubber offers a broad portfolio of food-grade sheet rubbers and sealing materials — including white neoprene, white nitrile, white EPDM, and Santoprene® food‑safe TPE — all manufactured in the USA and available in a range of durometers and thicknesses.
These materials are formulated and tested to meet FDA/NSF requirements for non‑fatty food contact, supporting repeated use in processing and packaging equipment.
Because Hanna Rubber is both a manufacturer and knowledgeable technical partner, customers benefit from optimized material recommendations and custom solutions tailored to their specific sealing applications — whether for O‑rings, gaskets, or custom molded profiles.
Key Benefits & Applications
- Regulatory Compliance & Food Safety — All Hanna Rubber food-grade seals meet FDA/NSF standards, ensuring non-toxicity, odorlessness, tastelessness, and suitability for direct food contact.
- Durability Under Stress — Materials like food-grade EPDM or Santoprene® maintain integrity under exposure to water, steam, sanitizing agents, and temperature fluctuations — ideal for cleaning-in-place (CIP) or sterilization cycles.
- Operational Reliability and Reduced Downtime — Properly specified and installed seals prevent leaks, contamination risks, and unplanned shutdowns — protecting product quality and throughput.
- Flexibility & Customization — From standard gasket sheets to custom-cut or molded parts, Hanna Rubber supports a variety of food processing equipment: mixers, tanks, valves, packaging machines, and more.

FAQs
Q: What does “food-grade” mean for sealing materials?
A: “Food-grade” means the material meets regulatory standards (e.g., FDA, NSF) for direct or incidental contact with food. This ensures non‑toxicity, no flavor or odor transfer, and resistance to leaching under processing conditions.
Q: Which rubber materials are commonly used in food‑grade seals?
A: Common materials include silicone, EPDM, nitrile (Buna‑N), neoprene, and food‑safe TPEs (e.g., Santoprene®). Each offers different strengths depending on temperature, chemical exposure, oil/fat contact, and cleaning protocols.
Q: Can food-grade seals withstand cleaning and sterilization processes?
A: Yes — when properly specified. High-quality food-grade materials like those from Hanna Rubber resist steam, hot water, and sanitizing agents, and retain elasticity after repeated CIP/SIP cycles.
Q: How do I choose the right seal for my food processing equipment?
A: Selection depends on food type (dry, wet, fatty, oily), processing temperatures, cleaning/sterilization methods, pressure/ mechanical stress, and regulatory requirements. Hanna Rubber’s technical team can help evaluate these parameters and specify the correct material and durometer.
