Custom Food-Grade Silicone Sealing Rings

Precision-Engineered Silicone Rings for Safe, Sanitary Sealing

Ensure the integrity and safety of your food and beverage products with CHENSHENG's custom food-grade silicone sealing rings. As a specialized extrusion factory, we craft high-performance seals by extruding precise profiles and seamlessly bonding them into flawless rings. This advanced process guarantees a perfect fit, exceptional durability, and absolute compliance with the highest food safety standards.

From lunch boxes to commercial food containers, our seals are designed to lock in freshness, prevent leaks, and provide a clean, reliable seal that consumers and businesses can trust.

Core Advantages: The CHENSHENG Quality Guarantee

• Certified Food-Grade SafetyYour customers' health is paramount. Our rings are made from 100% premium, food-grade silicone. They are non-toxic, odorless, and fully compliant with stringent international standards like LFGB and RoHS, ensuring they are completely safe for direct contact with food.

• Flawless & Seamless ConstructionA perfect seal requires perfect construction. Our specialized bonding technique creates a joint that is incredibly strong, clean, and virtually invisible. There is no glue overflow and no weak points, resulting in a uniform ring that performs like a single, molded piece and maintains its aesthetic integrity.

• Superior Resilience & DurabilityEngineered for repeated use, our silicone rings exhibit excellent resistance to deformation. They maintain their shape and sealing pressure even after countless cycles of opening and closing, ensuring a consistent, leak-proof fit for the life of your product.

• Exceptional Temperature StabilityFrom freezer to microwave, our seals perform flawlessly. They remain flexible and stable across a wide temperature range of -40°C to +230°C, making them ideal for a variety of food storage and preparation applications.
