Food Grade Flexitank Bulk Liquid Packaging Bag for Container Shipping

Food Grade Flexitank is an advanced bulk liquid packaging solution designed for safe, efficient, and cost-effective transportation of large-volume liquids. Installed inside standard 20ft containers, this flexible container liner transforms ordinary shipping containers into reliable liquid transport systems, providing an excellent alternative to traditional ISO tanks and rigid containers.

Made from high-quality multi-layer PE film with strong sealing technology, the flexitank offers excellent leakage protection, pressure resistance, and product safety. It is widely used for transporting food-grade liquids, edible oils, wine, fruit juice, water, chemicals, and industrial liquids. The food grade flexi bag meets strict hygiene requirements and helps maintain product quality during long-distance transportation.

Compared with traditional liquid transportation methods, the disposable flexitank provides higher loading capacity, lower transportation costs, reduced cleaning expenses, and improved container utilization. Its lightweight and space-saving design also helps reduce logistics costs and increase supply chain efficiency.

Our bulk liquid packaging bags are available in different capacities and customized configurations, including valves, liners, and fittings, to meet various customer requirements. As a professional flexitank solution, it is widely used in global liquid logistics, food packaging, chemical transportation, and international container shipping systems.

The Flexitank Has The Below Main Features:

Cost Saving: 33% payload more than iron barrels.

Resource Saving: More resource to be saved (such as labor, space, equipment)

Transporation advantage: Higher utilization rate and lower transporation cost in containers compared to ISO Tanks.

Raw material: Reduce less waste of forest resources compared to wood or paper package.

Packing: Less material required to pack each ton of cargo compared to any other packaging methods.
Environmentally Friendly: No need washing, no polluted water comapred to ISO Tanks and IBC.

Food safety: Single use, no cross contamination and no influence upon cargo quality.

Convenient: higher efficiency to load and discharge.

Other Characteristics:

Advanced Multi-Layer Coextrusion Design:

Constructed from a proprietary blend of high-strength, food-grade polyethylene and engineered elastomers, the liner offers exceptional tensile strength and puncture resistance. Its layered structure includes specialized barrier materials to mitigate permeation and preserve product integrity.

Intelligent Baffle Configuration:

Features an optimized baffle system that dynamically adapts to liquid movement during transit. This design reduces hydraulic surge, enhances stability, and minimizes stress on container walls, ensuring safe transportation across long distances.

Customized Material Formulations:

Tailored film compositions are available to address specific cargo requirements, including UV stabilization for deck stowage, anti-static properties for sensitive fluids, and oxygen barrier layers for products prone to oxidation.
