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.
The design and development of the packaging system has come under close scrutiny with a great deal of emphasis placed on the integrity of the final product.
Although factors such as type of package, materials of construction, size and desired outcome all add to the equation of flexible package integrity, the seal leak strength is an important element.
Flexseal was developed in response to an industry wide need for improved quality assurance of packaged food products. It is a useful tool for the manufacturer of product, needing an airtight package, where protection of the internal product from environmental elements is necessary to ensure the end user of quality.
Once all considerations of package material and design have been finalised and a validated 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 integrity of the seal ie: the seal may be strong but will still allow air to pass through.
* Provides the user with a valuable visual method of determining the integrity of the package and seal.
* Simple process is quick and easy to monitor.
* Allows rapid detection of failures.
* Enables early corrective action to be taken.
* Product programmable.
* Adjustable air pressure.
Flexseal operates up to 50 programmable menus involving various selections of submersion time, applied air pressure and product selection.
Once the operator has loaded the menu relevant to the product under examination, Flexseal proceeds 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.
Flexseal can also be used to determine the creep and burst properties of seals.
