Heat seal tester or the heat sealer is an accurate instrument which has a wide application in the flexible films and packaging industry. This is a consistent tool which helps in providing the flexible film manufacturer with the seal strength or the heat seal strength of the laminate and flexible films. The instrument consists of jaws which have a pneumatic operation with the help of which sealing can take place easily and more accurately. The instrument also has a PID digital controller and temperature controller for both jaws.  Heat seal tester has a digital LED display. The 300 MM heat seal tester has wide jaws and provide consistent sealing ability of the sample


The specimen is exposed to consistent pressure and heat in a fixed period of time. This procedure helps in measuring the heat seal performance of films, plastic films which are used in packaging different food products.


The instrument also adheres to international test standard like Standards: ASTM F 2029

Working principle of heat seal tester

The heat seal tester is the most widely used lab testing instrument that is designed to aid manufacturers in sealing flexible packaging products to cut off exposure to the environment as it may cause contamination to perishable and sensitive items packed inside. The sealing process also prevents the leakage of products and thus helps in shipping. The heat seal tester has 300 mm jaws with different surfaces that allow variable sealing types to be conducted on the specimen. These jaws perform sealing by elevating the jaw temperatures and shaping the specimen in a diamond, zig-zag, or plain surface.

Applications of heat seal tester

  • Packaging industry
  • Sealing Perishable items
  • Sachets for medicinal purposes
  • Beauty & skin care products

Advantages of heat seal tester

The heat seal tester is an extremely advantageous lab testing equipment to be utilized by manufacturers from the flexible packaging industry as it helps manufacturers in achieving high levels of accuracy while sealing the specimen. The instrument also determines the sealing quality and determines the uncertainties at this stage before the product is out in the market to prevent customer discomfort. The instrument is offered in variable jaw sizes that allow the operator to conduct the test on even bigger packaging material.
