Sealing a package correctly is essential to extending its shelf life and maintaining the quality of its contents. This is especially true for perishable items such as food products, where even a small breach in the packaging can lead to spoilage. Thus, we have come up with one of the effective lab testing instruments known as the heat seal tester. This is one of the amazing lab testing equipment that has been specially designed to fulfill the requirement of sealing packets in the paper and packaging industry. This testing instrument is highly used to seal several products like packaging material, and thermoplastic material, using heat.
A heat Sealer is a highly advanced testing instrument that is used to seal flexible packaging products, and other thermoplastic materials. This lab testing instrument is used in testing laboratories for various research and analysis purposes. It is capable of creating very high temperatures for testing and studying the effect on different thermoplastic materials that are used in plastic and packaging industries and other industrial laboratories. It is a tabletop model with a robust design that can efficiently work in harsh working conditions too. Here in this blog, we are going to provide you with information about how the heat seal tester is useful in testing the sealing capacity of thermoplastic materials to similar thermoplastic materials. So, let us get started!

What is a heat seal tester and for what purpose it will be used?
As the packaging industry continues to evolve, manufacturers are looking for new ways to stand out from the competition. One trend that is gaining popularity is the use of flexible packaging. Flexible packaging offers a number of advantages over traditional options, such as improved product visibility and increased shelf life.
Stand-up pouch bags are one type of flexible packaging that is becoming increasingly popular with food manufacturers. These bags are made from several layers of plastic and are designed to protect food from degrading. The stand-up design also allows for more efficient use of space, both on store shelves and in consumers’ homes. As consumers become more interested in convenient and sustainable packaging options, it is likely that flexible packaging will continue to gain in popularity. Thus, testing the heat sealing capacity of these products is essential.
Features of heat seal tester
The heat seal testing instrument has been equipped with several advanced features that make it easier for you to determine the heat sealing effect of thermoplastic materials with ease. Below we have listed them:
Three jaws of different patterns are available plain, diamond knurling, and straight line.
The temperature of the heaters is adjustable.
It is feasible to adjust the temperature of both the heaters of the machine individually.
The machine is incorporated with an imported P.I.D. temperature controller.
The dwell time of the machine can be adjusted from 0.1 – to 99.9 sec seconds.
It has a microprocessor-based digital display.
Identify Heat Seal Strength of Packaging Materials
Due to the growing packaging world, the Form-Fill-Seal machine is required by many industries like cosmetics, pharmaceutical, food etc. Form fill seal (FFS) machines are devices that form the package, fill it with either wet or dry product and seal it to close. Various FFS systems utilise flexible film to create the primary package like pouch and bag. The filling method uses a method in which the product is dropped into the package from a pre-set height that affects the bottom section of the package. In case the bottom area is not rigid to bear the impact, it ruptures and the package breakage is there in the industry line.
The reason is the low heat seal strength. In real time production, the time period between the process of heat sealing and product filling is very less. So, the sealing area does not get enough time to cool down completely. Hot seal strength tester is used by the manufacturers to evaluate the minimum heat seal parameters for the packaging materials.
Hot tack force is the adhesive strength of packing materials in hot temperature before cooling down. A force in the packaging material ensures the normal working flow of the filling production system. This force affects directly to the filling efficiency and the package breakage rate in the industry. To measure the quality and durability of packages, hot tack testing is required as an important part of package manufacturing.
Hot Tack Tester uses hot tack testing method to measure the heat seal strength made from thermoplastic surfaces immediately after the seal is done and before it cools down to room temperature. The heat seal property is important for the material that is used to form-fil-seal packaging as it uses vertical product filling.
Benefits of heat seal strength testing are:
It helps to evaluate the mechanical strength of the seal that helps to analyse proper material bonding to maintain package integrity throughout package life.
Information that we get through testing is used to validate the package design sufficient to maintain the package integrity.
To monitor process performance and assure a period of validity for performance.
Helps in ensuring control of the peel.
Threshold sealing temperature i.e. least temperature at which the hot tack strength is obtained.
Seal strength is the maximum peak force.
Hot tack temperature range is the minimum range at which the required hot tack strength is achieved.
Hot Tack Tester is an important part of form-filled sealing production to enhance the efficiency of work and maintain the brand name in the competitive world.
