Food and beverage companies around the world rely on bulk liquid transportation solutions to move products efficiently across international supply chains.
For products such as edible oils, wine, juice concentrates, syrups, and food ingredients, transportation safety is a critical consideration.
A food grade flexitank is specifically designed for transporting food-contact liquids in bulk quantities while maintaining product quality during transportation.
However, not all flexitanks are suitable for food applications.
When selecting a food grade flexitank manufacturer, buyers should evaluate:
l Food-contact material compliance
l Manufacturing quality control
l Certification systems
l Product compatibility
l Production traceability
l Global technical support
This guide explains what food-grade flexitanks are, which certifications matter, what liquids they transport, and how companies can choose a reliable supplier.
A food grade flexitank is a flexible bulk liquid container manufactured with materials designed for contact with food products.
It is installed inside a standard shipping container and allows companies to transport large volumes of liquid products through international logistics networks.
A food-grade flexitank typically includes:
l Multi-layer food-contact polyethylene film — Provides liquid containment and barrier properties
l Reinforced outer layers — Enhances structural integrity during transit
l Food-compatible valve systems — Enables controlled filling and discharge
l Protective components — Corrugated paper rolls, bulkheads
l Quality-tested sealing structures — Ensures leak-proof performance
The design focuses on:
l Product safety
l Leak prevention
l Transportation stability
l Maintaining product quality
Food products are often transported in large volumes across continents.
Flexitanks allow companies to ship thousands of liters of liquid products using standard containers.
Typical capacity:
l 20ft food grade flexitank: Approximately 14,000–26,000 liters
Actual capacity depends on:
l Product density
l Container specifications
l Flexitank design
Compared with multiple smaller containers, flexitanks simplify bulk liquid transportation.
Potential advantages include:
l Fewer handling units
l Reduced packaging complexity
l More efficient loading operations
Food products may be sensitive to:
l Oxygen exposure
l Contamination risks
l Temperature changes
l Material compatibility issues
Professional food grade flexitank manufacturers design products according to cargo requirements.
Food-grade flexitanks are widely used for:
Common products include:
l Palm oil
l Rapeseed oil
l Vegetable oil
l Sunflower oil
l Soybean oil
Important considerations:
l Food-contact compliance
l Material compatibility
l Oxidation protection
Wine transportation requires careful consideration of:
l Flavor preservation
l Oxygen transmission
l Material neutrality
Professional suppliers provide wine-compatible solutions designed to minimize product quality changes.
Used for:
l Fruit juice concentrates
l Beverage ingredients
l Liquid food products
Key requirements:
l Food safety compliance
l Leak prevention
l Product protection
Flexitanks are also used for:
l Syrups
l Sweeteners
l Food additives
l Liquid ingredients
For high-viscosity products, suppliers should consider:
l Discharge performance
l Valve selection
l Residue control
When evaluating food grade flexitank suppliers, certifications are one of the most important factors.
For the U.S. market, food-contact materials are evaluated according to:
FDA 21 CFR requirements
This helps demonstrate that materials are suitable for intended food-contact applications. LAF flexitanks meet FDA food-grade requirements and are manufactured with 100% virgin PE resin to ensure safety.
For European markets, plastic food-contact materials are evaluated according to:
EU Regulation 10/2011
This regulation covers requirements for plastic materials intended to contact food. LAF production processes meet EU food safety regulations for plastic packaging in direct contact with food.
FSSC 22000 is a recognized food safety management certification system.
It demonstrates that a manufacturer has established structured food safety management processes. LAF is among the earliest flexitank manufacturers in Asia to obtain FSSC 22000 certification.
Depending on customer requirements and target markets, some food manufacturers also require:
l KOSHER certification
l HALAL certification
These certifications may be important for specific food supply chains. LAF flexitanks are certified to both Kosher and Halal standards.
ISO 9001 demonstrates the implementation of quality management systems.
It is commonly considered when evaluating industrial suppliers. LAF production is carried out in accordance with ISO 9001 requirements.
A professional food grade flexitank factory typically controls multiple production stages.
Manufacturers select materials based on:
l Food-contact requirements
l Product characteristics
l Transportation conditions
LAF uses 100% virgin new PE resin for film production, with no recycled materials added, ensuring food safety and quality consistency.
The multilayer film structure is produced to provide:
l Strength
l Flexibility
l Barrier performance
Manufacturing processes include:
l Film cutting
l Heat sealing
l Valve installation
l Component assembly
Professional manufacturers conduct testing such as:
l Film strength testing
l Seal strength testing
l Valve inspection
LAF's production is carried out in full accordance with FSSC 22000 and ISO 9001 requirements, with all materials undergoing sterilization to meet edible packaging standards.
Before selecting a supplier, buyers should evaluate the following.
Ask:
l How long has the company manufactured food-grade flexitanks?
l Does it serve food and beverage customers?
l Does it understand different liquid applications?
Confirm:
l Food-contact documentation
l Material specifications
l Testing reports
Evaluate:
l Production control
l Traceability
l Inspection procedures
International transportation requires support including:
l Installation guidance
l Loading instructions
l Unloading recommendations
