Reliable Waterproof and Thermal Insulation Solutions for Container Door Sealing
In the logistics and transportation industry, truck containers play a critical role in protecting goods during long-distance shipping. Containers are frequently exposed to rain, humidity, dust, extreme heat, and temperature fluctuations. A high-quality container door sealing system is essential to prevent water leakage, heat loss, and cargo damage. Our PVC soft and hard co-extruded container door seals are specially engineered to meet these demanding requirements.
These truck container seals are manufactured using advanced PVC co-extrusion technology, combining rigid PVC and flexible PVC into one integrated profile. The hard PVC section provides strong structural support, ensuring the seal stays firmly in place on the container door frame. The soft PVC section creates a tight and flexible sealing surface, allowing the seal to adapt to slight deformations of the door and maintain excellent sealing performance over time.
This soft-hard combination offers superior durability compared to traditional rubber or single-material seals, making it ideal for heavy-duty container applications.
Water intrusion is one of the most common causes of cargo damage. Our PVC container door seals effectively prevent rainwater, moisture, and splashes from entering the container, even in harsh weather conditions. The flexible sealing lips form a tight barrier around the container doors, ensuring reliable waterproof protection throughout transportation and storage.
In addition to waterproofing, these PVC co-extruded seals provide excellent thermal insulation. By minimizing air exchange between the inside and outside of the container, they help maintain a more stable internal temperature. This is particularly important for transporting temperature-sensitive goods, such as food, electronics, chemicals, or industrial materials.
PVC material is naturally resistant to corrosion, rust, and chemical exposure. Unlike metal components, it does not oxidize, and unlike some rubber materials, it is less prone to cracking or aging. These container seals perform reliably in humid, coastal, and industrial environments and require minimal maintenance over their service life.
Designed with practicality in mind, these PVC container door seals are easy to install and replace. They can be quickly fitted onto container door frames without complex tools, reducing installation time and labor costs. Once installed, the rigid PVC section ensures a secure and stable fit, even with frequent door opening and closing.
We offer a wide range of standard colors, and custom colors are also available to meet branding or specific application requirements. Sizes, profiles, and lengths can be customized according to your container design, ensuring compatibility with different truck containers and shipping containers.
These PVC soft and hard co-extruded seals are widely used in:
Truck containers
Shipping containers
Cargo boxes
Logistics and transportation vehicles
Industrial container doors
They are suitable for both new container manufacturing and replacement or maintenance projects.
With their durable structure, excellent waterproof and thermal insulation performance, corrosion resistance, and easy installation, PVC soft and hard co-extruded container door seals are a cost-effective and reliable sealing solution for the logistics industry.
If you are looking for high-performance container door seals with customizable colors and sizes, our PVC co-extruded seals are designed to meet your needs.
