Balloon Burst Tester

Flexible packaging may experience pressure during filling, storage, handling, and transportation. Even a package that looks properly sealed can contain weak joints that may open under pressure.

The Pacorr Balloon Burst Tester introduces compressed air into the package at a controlled rate. As the internal pressure increases, the pouch expands until the packaging material or seal fails. The machine displays the maximum pressure reached at the time of failure.

This test helps manufacturers evaluate the combined performance of the packaging material, seal quality, and pouch construction.

​How Does the Balloon Burst Tester Work?
The flexible pouch is positioned securely inside the pneumatic clamping system. A puncture probe is inserted into the package, and compressed air is supplied at a controlled rate. The pouch gradually expands as the internal pressure increases. When the seal opens or the packaging material bursts, the machine records the maximum pressure reached. The operator can also inspect the failure location, such as the side seal, top seal, pouch corner, or packaging material body.

Applications
The Balloon Burst Tester can be used for testing:

• Plastic pouches
• Laminated packaging
• Flexible bags
• Heat-sealed sachets
• Aluminium foil pouches
• Food packaging
• Pharmaceutical pouches
• Medical packaging
• Cosmetic refill packs
• Chemical product sachets

The suitability of the machine depends on the sample dimensions, packaging material, and expected burst pressure.

Why Is Balloon Burst Testing Important?
Burst testing helps manufacturers detect weak seals and packaging defects before products reach the market. It can also be used to compare different materials, pouch designs, and sealing conditions.

Regular testing helps manufacturers:

• Identify weak sealing areas
• Improve sealing temperature and pressure settings
• Compare different packaging materials
• Reduce pouch leakage
• Maintain consistent production quality
• Investigate packaging failures
• Establish quality acceptance limits
• Reduce product rejection and customer complaints

Applicable Testing Standards
Depending on the package type and machine configuration, testing may be carried out according to the principles of:

• ASTM F1140/F1140M
• ASTM F2054/F2054M

ASTM F2054 testing may require suitable restraining plates. Customers should share their required testing standard before ordering so that the correct machine configuration can be recommended.

Balloon Burst Test vs Leak Test
A balloon burst test measures the maximum internal pressure a package can withstand before failure. It is a destructive test because the pouch is pressurised until it bursts or its seal opens. A leak test is used to detect small holes, channels, or openings in the package. A package may have good burst strength but still contain a small leak. For complete packaging evaluation, both tests may be required.

Factors Affecting Test Results
Reliable comparison requires consistent testing conditions. Results may be affected by:

• Packaging material and thickness
• Pouch dimensions
• Seal width
• Sealing temperature
• Sealing pressure
• Air pressure increase rate
• Probe position
• Sample conditioning
• Clamping position
• Use of restraining plates

The same procedure should be followed for every production batch.

Frequently Asked Questions

Q1. What is a Balloon Burst Tester?
A Balloon Burst Tester measures the maximum internal pressure a flexible package can withstand before its material or seal fails.

Q2. Which packages can be tested?
It can be used for flexible pouches, plastic bags, laminated sachets, foil pouches, and other sealed flexible packages.

Q3. What is the pressure range of the machine?
The standard published pressure range is adjustable from 2 to 5 bar.

Q4. Does the machine use pneumatic clamping?
Yes. Pneumatic clamping holds the specimen securely during testing.

Q5. Is balloon burst testing the same as seal strength testing?
No. Balloon burst testing checks the complete package under internal pressure. Seal strength testing measures the force required to separate a specific section of the seal.

Q6. Can the machine test according to ASTM F2054?
Testing according to ASTM F2054 may be possible with suitable restraining plates and the required machine configuration.

Q7. What is the price of Pacorr’s Balloon Burst Tester?
Pricing usually falls between ₹55,000 and ₹1,50,000, depending on the model and features selected. For a tailored quote, it's best to connect with the Pacorr team directly.
