Flexible Liquid Packaging vs Rigid Containers: How Should B2B Buyers Choose?
Rigid bottles, jerry cans and other molded containers are widely used for liquid products.
However, some manufacturers and distributors also evaluate flexible liquid packaging when they want to review empty-package storage, transportation, carton systems or dispensing options.
The question is not whether one packaging format is always better than another.
A more useful question is:
Which packaging structure fits your liquid, filling operation, supply chain and end-use requirements?
LIQPACK’s main carton-supported liquid packaging products include Cubitainer and Cheertainer.

What Is the Main Difference Between Flexible and Rigid Liquid Packaging?
Rigid packaging keeps most of its external shape whether it is empty or filled.
Examples include:
- Plastic bottles
- Jerry cans
- Rigid plastic containers
- Drums

Collapsed Cubitainer
Filled Cubitainer
Cheertainer in carton
Flexible or collapsible packaging can reduce its empty volume before use.
Within LIQPACK’s current product range:
Cubitainer uses an LDPE body and has a thicker, more defined structure.
Cheertainer uses PE + PA film and forms a flexible form-fit package inside an outer carton.
Both formats can be used with cartons as part of a complete liquid packaging system.

Empty Storage and Transportation
One practical difference appears before the package is filled.
Rigid containers continue to occupy their full external volume while stored and transported empty.
Collapsible or flexible formats can reduce empty-package volume, which may be useful for buyers importing or storing large quantities of empty packaging.
However, the correct comparison should include the complete system:
- Inner container
- Outer carton
- Pallet arrangement
- Accessories
- Transport method
Buyers should not compare the empty inner container alone.
Filling Process: Can the Existing Line Handle a New Packaging Format?
Packaging selection should always be checked against the customer’s filling operation.
Before changing from a rigid container to Cubitainer or Cheertainer, buyers should confirm:
- Manual or automatic filling
- How the package is positioned during filling
- Whether the neck requires support
- Closure installation
- Carton assembly
- Existing filling equipment
A packaging format may offer logistical advantages but still require changes to the filling process.
The production workflow should therefore be reviewed before the packaging change is confirmed.
Carton-Supported Packaging vs Standalone Rigid Containers
Many rigid bottles and jerry cans are designed to function as standalone packages.
Cubitainer and Cheertainer are commonly evaluated together with an outer carton for storage and transportation.
This means the buyer should compare:
Rigid container system versus Inner container + closure + carton system
instead of comparing only the plastic component.
Carton dimensions, stacking, handling and pallet arrangement should therefore be part of the packaging decision.

Dispensing and Closure Options
Another difference is how the liquid will be used after shipment.
Depending on the application, LIQPACK packaging can be matched with different closure or dispensing options such as:
- Standard screw cap
- Plastic tap
- Nozzle / guide tube
- Gel dispensing accessories
- Vented cap
The correct option depends on the liquid and the end user’s operation.
For example:
- AdBlue may require a pouring nozzle.
- Ultrasound gel may require a gel dispensing accessory.
- Some liquid fertilizer projects may require evaluation of a vented cap.
- Food liquids may use a plastic tap for repeated dispensing.

Which Applications Fit Cubitainer or Cheertainer?
Packaging should follow the actual liquid application.
Hematology Reagent
20L Cubitainer is LIQPACK’s main direction for hematology reagent packaging.
Liquid Fertilizer
For liquid fertilizer, Cheertainer is currently the priority direction, while Cubitainer can also be considered.
Ultrasound Gel
5L Cubitainer and 5L Cheertainer can both be evaluated with suitable gel dispensing accessories for ultrasound gel.
AdBlue / DEF
For AdBlue / DEF, Cubitainer and Cheertainer can both be considered, commonly with a nozzle or guide tube.
Liquid Detergent
For liquid detergent, Cheertainer is one of LIQPACK’s important current application directions.
When May a Rigid Container Still Be the Better Choice?
Flexible packaging is not automatically the best option for every project.
A rigid container may remain more practical when:
- The existing production line is specifically designed around it.
- The end user requires a standalone container.
- The distribution system already depends on rigid packaging.
- Changing packaging would require major operational changes.
- The actual liquid has not yet been evaluated with the alternative packaging.
This is why LIQPACK recommends comparing the complete packaging workflow rather than selecting a format based on only one advantage.
Flexible Liquid Packaging Buyer Checklist
Before deciding whether to test Cubitainer or Cheertainer, confirm:
- What liquid will be filled?
- Required capacity?
- Current packaging?
- Current closure?
- Filling method?
- Outer carton requirement?
- Storage period?
- Transportation method?
- Dispensing requirement?
- Estimated purchasing quantity?
When these details are clear, the packaging supplier can evaluate the project more accurately.
Flexible Liquid Packaging vs Rigid Containers
Is flexible liquid packaging always better than rigid packaging?
No. The better option depends on the liquid, filling process, storage, transportation and end-use requirements.
What is the difference between Cubitainer and Cheertainer?
Cubitainer uses LDPE and has a thicker, more defined structure. Cheertainer uses PE + PA film and is thinner and lighter.
Can Cubitainer and Cheertainer replace a rigid jerry can directly?
A direct replacement should not be assumed. The filling process, carton, closure, liquid compatibility and distribution system should first be reviewed.
Do Cubitainer and Cheertainer need cartons?
They are commonly used together with outer cartons as part of the complete packaging system.
How should I decide between Cubitainer and Cheertainer?
The choice depends on application, liquid characteristics, required capacity, filling method, closure, carton and transport requirements.
Considering a Change from Rigid Liquid Containers?
Tell LIQPACK what liquid you package, your current container, required volume, filling process and expected purchasing quantity. We can help you review whether Cubitainer or Cheertainer is worth evaluating.
