Precision Temperature Control Technology
Precise temperature control within ±2°C ensures that each seal is optimized, preventing damage to the packaging material caused by overheating or poor sealing due to insufficient temperature.
High-Speed Automation
It can perform more than 100 sealing operations per minute, tripling efficiency compared to traditional equipment, significantly shortening production cycles, and meeting the demands of large orders.
Top-Quality Inspection
By combining extensive experience with our quality inspection system, we can identify sealing defects in real time, reducing the defect rate to less than 0.1% and ensuring that every product meets the highest standards.
Versatility
Supports a wide range of packaging materials and sizes, from small snack bags to large vacuum-sealed packages, with quick changeovers that require no downtime, allowing for flexible adaptation to market demand.
Silicone Sealing Strip
Due to its excellent resistance to high and low temperatures, non-toxic and odorless properties, and good elasticity, silicone sealing strips are widely used in the sealing units of food packaging machines and vacuum packaging equipment. They ensure the airtightness of packaging bags, effectively extending the shelf life of food and preventing cross-contamination.
High-Temperature-Resistant Gaskets
Made from materials such as PTFE or specialty rubber, these products offer excellent resistance to high temperatures and corrosion. In hot-press sealing machines and retort sterilization equipment, they are used to seal flange connections and access ports, withstanding high-temperature, high-pressure environments to prevent steam or liquid leaks and ensure operational safety.
O-Ring
Made of food-grade rubber or silicone, these components offer excellent sealing performance and wear resistance. They are commonly used in pumps, valves, pipe connections, and filling equipment in food processing facilities to effectively prevent leaks of liquids, gases, and particles, ensuring the cleanliness and hygiene of fluid systems.
Food-Grade Sealant
It complies with food safety standards, is non-toxic and harmless, and offers excellent adhesion and water resistance. It is used to fill small gaps and seams in food equipment after assembly—such as the interior walls of refrigerated cabinets and the edges of work surfaces—to form a durable and hygienic seal that prevents bacterial growth and the infiltration of contaminants.
