Newly Arrival Plants Tester - H0005 – Hot Tack Tester – Drick

The Hot Tack Tester is an advanced system for monitoring the seal performance of flexible

and semi rigid plastic bags or tubes.

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.

Benefits:
Provides the user a means of determining key sealing parameters.
The simple process is quick and easy.
Useful for quality control.
Precise, repeatable test circuits.
Able to test and inspect incoming material.
Data can be viewed in a graph or numerically.
Related to product development and quality control through the

whole manufacturing chain of flexible packages.
Optimisation of the packaging process.
Optional ability to record data for future comparisons via RS232.
Optional ability to print results for hard copy storage.
Complies to ASTM F1921

Touch Screen Operation

Operation:
The Hot Tack test Setup page is used to allow the Operator to enter the required

parameters of a test. These include:
Test Nr Thickness Operator Temperature Lab Temp Dwell time Humidity
Seal pressure Sample Width Cooling time Separation rate

Once the test parameters have been selected by the operator, the sample strip can be

loaded into the sample clamps before pressing Start at which stage the Hot Tack Tester

automatically places the sample between the heated sealing jaws, closing the jaws for the

preselected time in milliseconds, removing the sealed sample strip and, with no delay, begins

the peeling process.

Set Up Screen

The Hot Tack Test prompt page will appear after a Sample test has been completed.

The Operator must then enter the Failure Mode. The standard points out that a number

of different failure modes could occur in the course of the failure of the strip, the Hot Tack

Tester allows an operator to enter one of seven Failure modes. If the operator is not satisfied,

then the Repeat Cycle button can be touched, the test will not record any results and the

Cycle and Sample number will remain the same.
