Leak detection system for flexible packaging

Supplier News

IDM Instruments, in conjunction with Amcor Research and Technology, has designed and manufactured Flexseal, an advanced leak detection system for monitoring the seal performance of flexible and semi rigid packages.

A spokesman for IDM said Flexseal had been developed in response to a need for improved quality assurance of packaged food products. Flexseal was a useful tool for manufacturer s needing an airtight package

“Once all considerations of package material and design have been finalised and a sealing process employed, one of the ways of effectively monitoring the integrity of the package is to test the condition of the seal via Flexseal. Other testing methods, such as the hot tack test, can evaluate the strength of the seal, whereas Flexseal can detect the actual integrity of the seal, he said.

Flexseal was a simple process which allows rapid detection of failures and enabled early corrective action to be taken.

Flexseal operates up to 50 programmable menus involving various selections of submersion time, applied air pressure and product selection.,” the spokesman said.

”Once the operator has loaded the menu relevant to the product under examination, Flexseal can proceed to perform the test cycle. The product will then be subjected to selected air pressure while submerged in a bath of water, where the operator can view the location and leak rate of any bubbles emanating from the package.”

It could also be used to determine the creep and burst properties of seals, two other important factors in seal integrity, hew said.

Flexseal was very economical in comparison with other testing methods such as dye penetration, tracer gas and vacuum leak systems.
