Hot Tack Tester

Home » Hot Tack Tester

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 strength is an important element.

The Hot Tack Tester has been developed to determine the capability of a heat-seal join to hang together when it is stressed, at a specified time interval, while still hot from the sealing operation, but before it reaches ambient temperature. The overall design of a package can contribute or detract from the materials ability to provide hot tack during the sealing process.

Hot tack knowledge is a considerable concern as package seals must be able to withstand forces and stresses applied during the form filling process. By assessing the quality of seals key parameters, (sealing pressure, dwell time and temperature) optimum sealing conditions can be determined and therefore reflected on the production line. This new Hot Tack technology will aid in the research and development of flexible films used in the packaging industry.  A must have in any modern day quality laboratory.

An advanced system for monitoring the seal performance of flexible and semi rigid plastic bags or tubes. The Hot Tack test Setup page is used to allow the Operator to enter the required parameters of a test.
