Choosing the right IBC liner is about more than finding a bag that fits your container. The liner needs to be compatible with your cargo, container dimensions, filling and discharge methods, and operating conditions.
With different shapes, material structures, capacities, and valve configurations available, selecting the right combination helps support safe, hygienic, and efficient bulk liquid handling.
This guide walks you through seven key steps to help identify the IBC liner configuration that suits your application.
Step 1: What Are You Transporting?
Start by identifying the type of liquid you need to package. Cargo characteristics determine the material compatibility and performance requirements of the liner.
Common applications include:
Food Products: Juices, edible oils, syrups, liquid food ingredients, and condiments.
Industrial Oils & Fats: Lubricants, glycerin, industrial gear oil, and other industrial oils.
Non-Hazardous Industrial Liquids: Surfactants, polyols, propylene glycol, ethylene glycol, and other compatible liquid chemicals.
Different cargoes may require different levels of barrier protection, temperature resistance, and material compatibility.
Before selecting a liner, provide the cargo name and relevant properties, such as viscosity, density, and sensitivity to oxygen or moisture, where applicable.
Step 2: Which Container Are You Using?
IBC liners are designed to fit different types of containers, allowing bulk liquids to be handled through a range of packaging formats.
Common compatible container types include:
Paper IBC: Collapsible paper-based bulk liquid containers.
Bottle-in-Cage IBC: Rigid plastic inner bottle supported by an outer metal cage.
Turnover Box: Plastic or metal collapsible containers.
Open-Top Iron Drum: Open-top steel drums used for liquid packaging.
Container type is only the starting point. Actual dimensions and internal structure also matter.
Before ordering, confirm the container's internal length, width, height, opening dimensions, and any structural features that may affect liner installation or fit.
Step 3: What Capacity Do You Need?
IBC liner capacities range from 220 L to 1,600 L, depending on the liner design and intended container. The available capacity depends on the container's usable internal space, cargo density, and applicable loading limits.
Consider the following when confirming capacity:
The container's rated and usable capacity.
The cargo's density and total required loading weight.
Available headspace and filling requirements.
Applicable transport and handling limits.
Do not select a liner based on volume alone. The container dimensions and cargo weight must also be taken into account.
Step 4: Which Shape Works for Your Operation?
IBC liners are available in two main shapes: Cubic and Pillow-Shaped.
Cubic IBC Liner
Designed for square or rectangular container formats, cubic liners offer a shape suited to containers such as Paper IBCs and other compatible box-style packaging.
Typical capacity range: 1,000–1,400 L.
Pillow-Shaped IBC Liner
With a flexible pillow-like structure, this design can accommodate a wider range of container formats and capacities.
Typical capacity range: 220–1,600 L.
The choice between cubic and pillow-shaped designs depends on the container dimensions, available space, and loading and discharge arrangements.
Step 5: What Material Performance Is Required?
The material structure is one of the most important considerations when selecting an IBC liner. Different materials can be combined in multilayer film structures to provide the properties required for specific cargoes and operating conditions.
Common material options include:
PE (Polyethylene): Provides flexibility and sealing properties and serves as a key material in flexible liquid packaging.
EVOH: Provides oxygen barrier performance in appropriately designed multilayer structures, helping protect cargoes sensitive to oxygen exposure.
Nylon: Can be incorporated into multilayer structures where its mechanical properties are beneficial.
Aluminum Barrier Materials: Used in selected structures to provide enhanced barrier protection. Performance depends on the specific material configuration.
When evaluating material options, consider:
Cargo compatibility.
Oxygen and moisture barrier requirements.
Mechanical performance requirements.
Operating and filling temperatures.
Storage and transportation conditions.
For applications requiring enhanced barrier performance or temperature resistance, specialized liner structures may be available. The appropriate material combination should be confirmed according to the cargo and actual operating conditions.
Step 6: How Will You Load and Discharge?
The filling and discharge methods determine the liner's opening and outlet arrangements.
Top Loading
Cargo is filled through an opening or valve at the top of the liner. This is a common configuration for bulk liquid filling operations.
Top Discharge
Cargo is discharged through a top-mounted outlet, depending on the liner configuration and unloading setup.
Bottom Discharge
Cargo is released through a bottom outlet, supporting discharge from the lower part of the container.
When selecting the loading and discharge arrangement, consider the available equipment, operating space, unloading process, and the position of the container during handling.
Step 7: What Valve Configuration Do You Need?
The valve configuration should match your filling and unloading equipment.
Top Valve Options
Available sizes include:
1-inch
2-inch
3-inch
4-inch
Bottom Valve Options
Available configurations include:
2-inch Spigot
2-inch Butterfly Valve
The appropriate valve size and type depend on the filling or discharge equipment, required flow rate, cargo characteristics, and operating procedure. Confirm the valve position, connection type, and dimensions with your equipment supplier before finalizing the liner design.
Additional Considerations Before Ordering
Beyond the seven main selection steps, a few practical details can help avoid compatibility issues:
1. Operating Temperature
Confirm the expected filling, storage, and transportation temperatures. Temperature-resistant liner options may be required for certain applications.
2. Installation Space and Container Dimensions
Provide accurate internal container measurements and check for protrusions, corners, or other features that may affect liner installation.
3. Food Safety and Compliance
For food applications, confirm that the liner materials and manufacturing controls meet the relevant food-contact requirements for your destination market and cargo.
4. Filling and Discharge Equipment
Check that the selected valves and connections are compatible with your existing equipment and operating procedures.
