Model: H0005

The Hot Tack tester tests the sealing properties of a wide range of sealable materials. Heat seal applications are highly useful in many industries. Such as packaging, plastic and others. This machine ensures reduction in production time and cost. As it increases the speed of sealing. This is applicable to food manufacturers, film producers, packaging material manufacturers.

Heat sealing is useful for large number of applications. Especially for efficient flexible packaging, seal strength is important. These include polypropylene, cello firms, thermoformed cuprs, trays. As well as laminates and blisters. Also, non woven materials as they can bond by heat. Thus, this machine is useful for all these purposes.

This tester ensures accuracy and consistent performance. It guarantees fast and repeatable results. That too free from human intervention.

The Hot Tack Tester determines 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.

After a heat seal is made, it is probably subject to opening forces such as the weight of the fill. Hot Tack is simply the resistance to seal failure from these forces. This instrument also performs peel strength test by applying force to separate layers.

Hot tack knowledge is a considerable concern as package seals must be able to withstand forces and stresses. Which is  applied during the form filling process. By assessing the quality of seals key parameters which are sealing pressure, dwell time and temperature. These determine the optimum sealing conditions. Therefore reflected on the production line.

This new Hot Tack technology will aid in the research and development. Especially of flexible films used in the packaging industry.  This instruments is a must have in any modern day quality laboratory.
