FKT-200 Seal Tester

Product Overview

The FKT-200 Seal Tester is a dual-function seal strength and burst strength testing instrument designed for comprehensive package integrity evaluation of flexible packaging. Capable of pressurizing test specimens up to 200kPa, this compact device is fully compliant with the JIS Z0238 standard, making it the trusted choice for packaging quality control laboratories worldwide.

What sets the FKT-200 apart is its unique 2-in-1 capability: it is the only package integrity tester that measures both seal strength (peel force at the seal interface) and burst strength (pressure at package failure) in a single, portable instrument. This dual functionality eliminates the need for separate testers, saving valuable bench space and reducing capital expenditure.

From food packaging QC lines verifying retort pouch seal integrity to pharmaceutical labs testing blister pack seal strength, the FKT-200 delivers fast, repeatable results that keep production moving. Cosmetics manufacturers rely on it for sachet and tube integrity verification, while pet food producers use it to validate stand-up pouch seal performance.

Whether you are performing incoming material inspection, in-process quality checks, or final product release testing, the FKT-200 provides the data you need to ensure your packaging meets the highest standards of integrity and consumer safety.

How It Works

The FKT-200 operates in two distinct testing modes, each designed to evaluate a different aspect of package integrity:

Seal Strength Mode

In seal strength mode, the FKT-200 gradually increases internal air pressure within the sealed package. As pressure builds, the instrument continuously monitors and records the force at which the seal begins to peel apart. This peel force measurement directly quantifies the bond strength of the heat seal, providing critical data on seal quality and consistency. The gradual pressurization follows JIS Z0238 methodology, ensuring standardized and comparable results across production batches.

Burst Strength Mode

In burst strength mode, the FKT-200 rapidly pressurizes the package until it fails by rupture or seal blowout. A thin needle is inserted through a self-sealing grommet or dedicated port, and compressed air is delivered at an increasing rate. The peak pressure at failure is recorded as the burst strength, indicating the maximum internal pressure the package can withstand. This test is essential for evaluating packaging durability during transportation, stacking, and thermal processing.

A clear digital pressure readout displays real-time values in kPa, and the compact, benchtop-friendly design allows operators to perform tests quickly at any point in the production workflow. The FKT-200 ensures package integrity is maintained from the filling line through distribution to the end consumer.
