Balloon Burst Tester

If you are looking for the best testing instrument for testing the internal bearing strength of the packaging material, then we suggest you go with the Presto balloon burst tester. The materials like a paper pouch, heat-sealed plastic pouch, food packets, poly bags, carry bags, etc. can easily be tested with the help of this lab testing equipment. This is a destructive type of test to find bursting of pouches or carry bags due to filling or internal pressurization. A test specimen is held between two straight jaw-type clamps under sufficient pressure to minimize slippage. A small air nozzle outlet is provided to fill pressurized air in the pouch/bag. A highly precise pressure sensor is connected across the airline to detect the pressure of air. A microprocessor-based peak load monitor is provided to measure the Peak value of bursting pressure.

The main purpose of this testing instrument is to determine the bursting strength of a variety of packing pouches to study the failure that occurs in them due to an internal pressure built in the pouch at a steadily increasing rate through a pneumatic pipe. The equipment is provided with an electro-pneumatic mechanism driven which is used for increasing the air pressure inside the sample pouch at a specified rate. There is an arrangement provided with the equipment that automatically lowers the pressure down and stops air automatically when the test cycle is completed. It has a rugged design to provide trouble-free performance for a long time. With its single-push button, you can easily complete the operation and read the results in a digital readout. This amazing testing instrument will help to determine the seal integrity of materials. The test specimen is sealed from 3 sides and has an open side to inject the pressure. To perform the test, the machine simply starts injecting the pressure to a certain limit. The sample is then held in this position for a certain time. During this time, and leaks or deformities in the sealed edges are observed. Also, it has been assessed that for how long, the packet is able to bear the pressure. If during the test, the seals start to leak or packet bursts during the test, the sample is considered as failed. The machine is called a balloon burst tester because it blows up the test sample like a balloon. The pressure of the machine can be easily altered depending upon the test requirements. This test is gaining popularity in the flexible packing industry as it tells a lot about the quality of the packet. It is equipped with a nozzle to burst the pressure inside the packet. The machine is designed with an auto clamping feature. This assures that there is no slippage during the test when pressure is being applied to the sample. The machine is designed in a way to reduce human interference to the minimum. This assures more accurate results. Presto’s Balloon burst tester gives high precise results with high repeatability.

This testing equipment has an in-built pressure control system and has been made with Havel grey and blue powder coating with bright zinc plating for corrosion prevention. You can increase the pressure up to a certain pressure and check for leakages or you can keep increasing the pressure to measure the peak pressure before the pouch bursts.

If you want to operate this testing machine effectively, then you need to follow the below-mentioned steps. These easy-to-follow steps will help you in operating the machine accurately.

• Plugin the mains switch into a 3 Pin - 5 Amp. Power supply socket.
• Turn the mains Switch on.
• The Load indicator might show some readings due to previous test values.
• To set the pressure to zero, you can press the TARE button, Press RESET Button. Now the Load Indicator will show zero reading.
• Take a Test specimen of carrying bag type of polythene, paper, etc. . Move the upper clamp upwards with the use of a pneumatic cylinder by turning the rotary switch to the OFF position.
• Place the test specimen such that nozzle insert inside the bag through the opening. Now bring the upper clamp down on the test specimen with the help of the pneumatic cylinder by turning the switch to ON position.
• Make sure that the test specimen is firmly held and there are no chances of slippage.
• After the test specimen has been placed correctly, Press the Push button to burst the specimen.

In this way, you can easily commence the test with the help of the Presto Balloon bursting strength tester. If you find any difficulty in performing the test, then you can directly call or email us. We will provide you with the right assistance in solving all queries.
