305-BP-J Burst Strength Tester

Dedicated burst strength tester with easy needle insertion operation. JIS Z 0238:1998-8 compliant for numerical evaluation of package pressure resistance.

Product Overview

The 305-BP-J Burst Strength Tester is a dedicated instrument designed to measure the burst strength of flexible packaging materials. By applying controlled internal air pressure through a needle, it determines the maximum pressure a sealed package can withstand before failure—providing a clear, quantitative measure of package integrity.

Fully compliant with the JIS Z 0238:1998-8 standard, the 305-BP-J delivers results that are reliable, repeatable, and directly comparable across production lines, quality laboratories, and supplier facilities. The standard defines a uniform testing methodology for the numerical evaluation of package pressure resistance, eliminating subjective judgment from quality assessments.

Operation is straightforward: simply insert the needle into the package, initiate the test, and read the burst pressure value. This simplicity makes the 305-BP-J accessible to production floor operators without specialized training, supporting high-throughput quality control without bottlenecks.

Food manufacturers, pharmaceutical companies, cosmetics producers, and packaging converters rely on the 305-BP-J to verify that their packages can withstand internal pressure during transportation, storage, and handling—catching weak packaging before it reaches the end consumer.

How Burst Strength Testing Works

The 305-BP-J uses a needle insertion method to evaluate package pressure resistance. A fine needle is inserted through the package wall, and compressed air is gradually introduced into the sealed cavity. Pressure increases steadily until the package bursts at its weakest point.

The instrument records the maximum pressure reached at the moment of failure—this value is the burst strength. JIS Z 0238:1998-8 specifies the testing procedure, including pressure ramp rate and measurement conditions, ensuring that results obtained on the 305-BP-J are consistent and comparable regardless of where the test is performed.

This method is particularly effective for flexible packaging such as pouches, sachets, and bags, where internal pressure resistance is a critical quality parameter. The straightforward needle insertion requires no complex sample preparation, enabling rapid in-line or at-line testing.

Frequently Asked Questions

What standard does the 305-BP-J comply with?

The 305-BP-J Burst Strength Tester complies with JIS Z 0238:1998-8, the Japanese Industrial Standard for evaluating the pressure resistance of packaging through burst strength testing.

How does burst strength testing work?

A needle is inserted into the package and air pressure is gradually increased until the package bursts. The maximum pressure recorded at the point of failure is the burst strength value.

What packaging can be tested with the 305-BP-J?

The 305-BP-J is suitable for testing a wide range of flexible packaging including retort pouches, snack bags, frozen food packaging, pharmaceutical blister cards, medical pouches, cosmetic tubes, sachets, and shipping packaging materials.

What is the difference between burst strength and seal strength testing?

Burst strength testing measures the maximum internal pressure a sealed package can withstand before rupturing at its weakest point. Seal strength testing, by contrast, measures the force required to peel apart a sealed seam. Burst strength evaluates overall package integrity, while seal strength focuses on the bond quality of the seal area.

Is the 305-BP-J easy to operate?

Yes. The 305-BP-J uses a simple needle insertion method that requires minimal training. Production floor operators can perform tests quickly and consistently, making it ideal for routine quality control.
