What Is a Container Liner Bulkhead?
A container liner bulkhead is an internal packaging system installed inside a shipping container. The liner creates a clean barrier between the cargo and the container walls, while the bulkhead helps retain the cargo and reduce movement during transportation.
Depending on the application, the system can be customized with different materials, dimensions, openings, closures and reinforcement structures.
For customers shipping powders, granules or other dry bulk materials, a properly fitted container liner can also help reduce contact with moisture, dust and contaminants.
Why Is a Custom Container Liner Important?
A standard container has a rigid metal interior that is not designed to directly contain many types of bulk cargo. During loading and transportation, several problems may occur.
1. Moisture and Contamination Protection
Some bulk products are sensitive to moisture and contamination. A PE liner can provide an additional barrier between the cargo and the container interior.For applications requiring stronger protection, different liner thicknesses and sealing methods can be selected according to the product characteristics.
2. Better Use of Container Space
A properly designed liner follows the internal dimensions of the container. This helps maximize usable space while reducing unnecessary gaps.For products requiring stable shape retention, customized baffle PE liners can also be considered. Internal baffles help maintain a more stable shape and reduce excessive bulging after filling.
3. Safer Bulk Cargo Handling
The bulkhead is particularly important when large quantities of loose material are loaded directly into a container. It helps contain the cargo and reduces the risk of material shifting toward the container doors.The structure can be designed around the customer's loading and unloading process, including filling openings, discharge arrangements and fixing points.
How We Customize Container Liner Bulkhead Solutions
At Zibo Haosence Packaging Co.,ltd, we do not treat every container liner as the same product. The design is normally based on several technical factors.
Container Dimensions
The first step is confirming the container type and internal dimensions. A 20ft and 40ft container require different liner dimensions and configurations.
Cargo Characteristics
The material being transported affects the liner design. Powders may require better dust and leakage protection, while granular materials may require greater puncture and abrasion resistance.
Filling and Discharge Method
The location and size of filling and discharge openings should match the customer's existing equipment. Incorrect positioning can slow down loading or create unnecessary material loss.
Material and Thickness
PE is commonly used for liner applications because of its flexibility, moisture resistance and chemical resistance. Thickness can be customized according to the cargo and transportation conditions.
For FIBC applications, we also manufacture customized shaped PE liners designed to match the shape of the outer bulk bag.
From Drawing to Finished Product
For this customized container liner bulkhead project, our team first reviewed the customer's container dimensions, cargo requirements and loading process.
The structure was then confirmed before production. During manufacturing, dimensions, sealing and connection points were checked to ensure the finished liner matched the agreed design.
This customized approach is especially useful for customers who have:
Specific container dimensions
Automated filling equipment
Special cargo protection requirements
Bulk powders or granules
Long-distance ocean transportation
Strict loading and unloading requirements
Container Liner Bulkhead Manufacturer for Customized Projects
A container liner is not simply a plastic bag placed inside a shipping container. The liner, bulkhead, openings and fixing system need to work together as one transportation solution.
Zibo Haosence Packaging Co.,ltd provides customized bulk packaging solutions for industrial and export applications. Based on the customer's cargo, container size and handling process, we can develop the appropriate liner structure, material and configuration.
If you are sourcing a container liner bulkhead for bulk cargo transportation, send us your container type, cargo, loading method and required dimensions. We can review the requirements and provide a customized solution and sample for evaluation.
