F0022 - Flexseal

Product details

IDM Instruments, in conjunction with AMCOR Research ａnd Technology, have designed 

ａnd manufactured FLEXSEAL®, an advanced leak detection system designed for monitoring

 the seal performance of flexible and semi rigid packages.

The Necessity for Flexseal:
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. FLEXSEAL® 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.

Benefits:
• FLEXSEAL® provides the user with a valuable visual method of determining the 

integrity of the package and seal.
• The simple process is quick and easy to monitor the heat-sealing process in 

production.
• Allows rapid detection of failures.
• Enables early corrective action to be taken.
• Product programmable.
• Adjustable air pressure.

Other Testing Methods:
Some testing labs use Dye Penetration to test the seal integrity.  A low surface-tension 

solution and dye indicator is used to flow through any channels in the seal.  Although this 

is a sensitive lea
