In the packaging industry, heat sealing is one of the most important procedures that help to sell your product to protect it from getting damaged. Testing the effects of heating parameters is also important to determine the product quality. When the packaging film is not sealed properly then it would lead to product damage and also affect the performance of the product in real-time. Thus, to avoid this type of condition in product packaging, it is important for you to test the product easily. With Presto Laboratory Heat Sealer 500 mm (Model No: PLHS-24E), you can easily check the heat sealing integrity of various products like packaging films. This testing machine is designed as per Global testing standards like ASTM F2029 that makes the test more accurate and reliable. To know about the working of this testing instrument, we have listed some of the important steps of testing below:

  • Turn the machine on by plugging it in the main socket. After turning it on, you will be able to see some predefined readings on the PV and SV.
  • Set the SV on the PID controller along with the test duration timings on the digital timer.
  • Operate this testing machine by connecting the air source with the pressure gauge through the pressure inlet port.
  • To maintain the required pressure, you can make use of a pressure gauge and regulator. Place the specimen between two sealers and when the specimen will be accurately placed then you can start commencing the test.
  • When the specimen will be placed between two heated jaws in close contact, then it will help to create the bond between two pieces of the specimen to seal the sample.
  • The Specimen placed between two heated jaws in close contact helps to create a bond between two pieces of the specimen to seal the samples. The PID display will show an increase in temperature.
  • After completion of pre-set time, the upper sealer will go back to its home position. Take out the specimen and analyze the changes in the physical properties of the specimen.

In this way, you can successfully test the specimen using a Presto heat sealer.

MODEL:- PLHS - 24

Do you need to test the strength of plastic packaging? If yes, then we suggest you go with Presto Laboratory Heat Sealer 500 mm (Model No: PLHS-24E). This is one of the best testing instruments that The Presto heat sealer is an essential tool for any laboratory. It can be used to study how thermoplastics react under high temperatures, which will help you determine which materials are best suited for your product. This device has been designed with safety features that make it easy to use without risk of injury or damage to the equipment and yourself. You won’t find another machine like this one anywhere else – it’s truly unique and unparalleled by anything else on the market today. The main purpose of Presto heat sealer is that it is used to seal one thermoplastic to another or similar thermoplastic using heat and pressure. The direct contact method of heat sealing utilizes a constantly heated die or sealing bar to apply heat to a specific contact area or path to seal or weld the thermoplastics together. You can easily make use of this testing machine for different types of applications. It includes heat seal connectors, thermally activated adhesives, film media, plastic ports, or foil sealing.

The Presto Laboratory Heat Sealer 500 mm (Model No: PLHS-24E) is one of the best heat sealers in the market, that is used to test and analyze different thermoplastics in the packaging industry. If you want to make sure that your products will remain up to date, then we suggest you use our heat sealer. With this device, you can conduct tests without worrying about damaged products. This testing machine comes with a PID controller and can start the testing process at a fast pace. You will easily control the temperature and timer settings with the help of the control panel given in the machine. The control panel of this testing equipment consist of Digital Timer, PID For Upper Heater – 1, PID For Lower Heater – 2 Pressure Gauge, Pressure Regulator, Air Pressure Inlet, Test Start Push Button, Switch for Lower Heater – 2, Switch for Upper Heater – 1, and main switch. With the help of a PID controller, you can easily process the value, set value, and check the status of test completion. You can easily increase or decrease the given data value.

Thus, you can use this testing machine, to ensure the flexible packaging of thermoplastic films. The sealing of the specimen will be done by two main principles. The first one includes when the plastic will get melt and forms the uniform bond to create the seal. The second one comes when there is sealant on one side and the material will get bonded together. The heat of the sealer will activate the sealant and form the bond together.  Whenever you make use of this testing machine, then you should know the different range of temperature for this device. The material that you use should withstand the temperature range that you set for the testing. You can also consider the thickness of heat sealing material so that it cannot melt at high temperatures.

For large manufacturing firms, the dwell time of the machine matters a lot. This means, that the bond will be formed with the heating elements within a specific time. Dwell time has also affected the seal strength of the heat sealing machine and form a leak-proof seal. Presto offers a dwell timer with the machine which is used for setting the testing time up to 99.9 seconds. This easy-to-install testing instrument can be maintained easily and comes with a high heating capacity from ambient to 250 degrees Celsius.
