Bulk Container Liners

Sea Bulk Liners

A container liner or “sea bulk liner” is a protective packaging system designed to transport dry flowable goods efficiently and effectively in ocean shipping containers. The shipping container liner forms a shield between the product, walls, and floor of the container.

Shipping liners are filled via belt thrower, conveyor, pneumatic, or gravity-fed system. Their functional design provides for clean and complete discharge of the product. Bulk container liners can provide significant cost savings vs. traditional small bags and bulk bags.

Why Choose Our Shipping Container Liners?

When moving bulk goods by sea, over-the-road, or rail, preventing contamination and maximizing load efficiency is critical. Shipping container liners create a clean, food-safe barrier that reduces risk of moisture damage, protects against cross-contamination, and enables full utilization of container space.

Compared to smaller packaging formats, bulk container liners lower labor costs, improve loading efficiency, and reduce packaging waste. For products such as grains, sugar, resins, and fertilizers, using a container liner ensures consistent quality while keeping transport economical.

Frequently Asked Questions

What is a bulk container liner used for?

A bulk container liner, also called a sea bulk liner, is a protective packaging system installed inside ocean shipping containers to transport dry flowable goods without the need for individual bags. The liner forms a barrier between the product and the container's walls and floor, allowing for clean, complete discharge and full utilization of container space. Compared to smaller packaging formats like bulk bags or paper bags, container liners can reduce labor costs, improve loading efficiency, and lower overall transport costs for high-volume shipments of products like grains, resins, and fertilizers.

What size shipping containers do container liners fit?

Southern Packaging's bulk container liners are manufactured for use in 20', 30', 40', and 53' shipping containers. The right liner size and style depend on your container dimensions, loading equipment, and the product being transported - our team can help confirm the correct fit for your shipment.

How do polyethylene and polypropylene bulk liners compare?

Woven polypropylene liners offer higher tensile strength and are generally more rigid, making them well suited for heavier or more abrasive bulk materials. Polyethylene liners are more flexible and provide a stronger moisture barrier, which makes them a common choice for products sensitive to humidity. Southern Packaging offers both woven polypropylene and polyethylene film liners, along with PE/PET and foil laminate options for applications requiring additional barrier protection. Our team can help match the right material to your product's handling and protection requirements.

Are bulk container liners FDA approved and food safe?

Yes. Our shipping container liners are produced using 100% virgin resins approved by the FDA for food contact packaging, and manufactured in BRCGS / ISO 9001:2015 / ISO 22000 certified clean facilities. Liner material selection is based on the performance and food-safety requirements of your specific application.

Can bulk container liners be used for food-grade products?

Yes. Our bulk container liners are commonly used to transport food products such as beans, rice, grain, and sugar. Because they're produced from FDA-approved materials in BRCGS certified clean rooms, they meet the hygiene and safety standards required for food-grade bulk shipments. For products requiring additional contamination control, food-grade FIBC bulk bags may also be worth considering depending on your handling process.
