What Are You Looking For?
Our container sealing strips are engineered with advanced PVC soft and hard co-extrusion technology, integrating flexible sealing lips with a rigid mounting base in one continuous profile. This dual-material structure ensures both excellent sealing performance and strong structural stability, making the product highly suitable for shipping containers, trucks, trailers, and refrigerated vehicles.
The soft PVC layer provides outstanding elasticity and compression recovery, allowing the seal to tightly close gaps between doors and frames. This effectively prevents water leakage, air infiltration, dust, wind, and external contaminants from entering the cargo area. At the same time, the hard PVC section reinforces the profile, ensuring firm installation and long-term shape retention, even under frequent opening and closing cycles.
This co-extruded design allows the sealing strip to maintain consistent contact pressure, which is essential for preserving internal temperature in refrigerated transport and protecting sensitive goods from humidity and environmental exposure.
Unlike metal-based sealing systems, PVC does not rust or corrode. Our container seals are resistant to moisture, salt spray, UV exposure, and extreme temperature variations, making them ideal for long-distance logistics, maritime transport, and outdoor storage conditions. Whether operating in hot, cold, dry, or humid climates, the seals remain flexible and effective over time.
This corrosion-free and maintenance-friendly design significantly reduces replacement frequency and lowers long-term operating costs for fleet owners and logistics companies.
These PVC container sealing strips are widely used in:
Standard shipping containers
Box trucks and cargo vans
Semi-trailers and logistics vehicles
Refrigerated trucks and cold chain containers
They play a critical role in maintaining cargo safety by preventing moisture intrusion, minimizing temperature loss, and protecting goods from contamination. For cold chain transportation, proper sealing directly contributes to stable internal temperature and reduced energy consumption, helping improve overall transport efficiency.
Our sealing strips are designed for simple and reliable installation on container and vehicle door frames. The rigid PVC base ensures a tight grip on the mounting surface, while the flexible sealing lip automatically adjusts to door movement. This design allows for fast replacement and minimal downtime during maintenance.
We offer multiple profile shapes and sizes to match different door structures and sealing requirements. Custom molds and profile designs are also available to meet specific project needs.
We support custom dimensions, shapes, and performance requirements based on your application. Colors, hardness levels, and packaging options can also be customized. Each batch of sealing strips is produced under strict quality control to ensure consistent material properties, dimensional accuracy, and reliable sealing performance.
Our PVC co-extruded container seals comply with industrial standards for durability and environmental resistance, providing long-term reliability for commercial transportation use.
By creating a stable and secure barrier between the inside and outside environment, our container sealing strips help prevent leakage, reduce cargo damage, and improve overall transport safety. This not only protects valuable goods but also enhances customer satisfaction and reduces claims caused by transport-related losses.
Choosing high-quality container sealing solutions is an essential step toward building a safer, more efficient, and more reliable logistics system.
