HST-02 Heat Seal Tester

1.Introduction of Film Heat Seal Tester

Film Heat Seal Tester is used laboratory preparation of heat-seals and the treatment and evaluation of heatseal strength data for the purpose of determining heatsealability of flexible barrier materials, films, laminates, polymers, and composites, etc. It can also be modified to make heatseal samples of food trays, capsules, mixpap, etc.  As an advanced heat seal tester manufacturer, we offer a wide range of heat seal testing equipment, including blister strip heat seal testing and gradient heat seal testers.

2. Advantages of Film Heat Seal Tester

P.I.D. heat sealing temperature control

The Film Heat Seal Tester is equipped with a sophisticated P.I.D. (Proportional-Integral-Derivative) temperature control system. This advanced feature ensures that the sealing temperature remains stable and precise throughout the entire sealing process. The P.I.D. controller continuously monitors and adjusts the temperature to maintain the set point, which is crucial for achieving consistent and high-quality seals. Whether you are working with thin films or thick materials, the P.I.D. temperature control guarantees optimal performance and reliability.

Uniform heating realized by aluminum sealing jaws

The sealing jaws of the Film Heat Seal Tester are made from high-quality aluminum, which is known for its excellent thermal conductivity. This material ensures that heat is distributed evenly across the entire sealing surface, eliminating hot spots and cold spots that can lead to inconsistent seals. The uniform heating provided by the aluminum sealing jaws helps to achieve strong, reliable seals every time, making it an ideal choice for a wide range of applications.

Precise timer ensures accurate sealing time control

The Film Heat Seal Tester features a precise timer that allows for accurate control of the sealing time. This timer can be set to any desired duration, ensuring that each seal is consistent and meets the required specifications. Whether you need a short sealing time for thin films or a longer time for thicker materials, the precise timer ensures that the sealing process is repeatable and reliable. This feature is particularly useful in quality control and production environments where consistency is key.

Independent heating of upper and lower jaws to avoid heat loss

The Film Heat Seal Tester includes independent heating elements for both the upper and lower sealing jaws. This design ensures that each jaw can be heated to the desired temperature independently, reducing heat loss and improving energy efficiency. By maintaining the optimal temperature for both jaws, the tester can achieve better sealing results, especially when working with materials that require different temperatures on the top and bottom surfaces.

Sealing jaw customization available in dimension, shape, and surface, etc

The sealing jaws of the Film Heat Seal Tester can be customized to meet specific requirements. This includes adjustments in dimensions, shapes, and surface finishes to accommodate various materials and applications. Whether you need a flat sealing surface, a specific pattern, or a particular size, the customization options ensure that the tester can be tailored to your unique needs. This flexibility makes the Film Heat Seal Tester a versatile tool for research, development, and production environments.

Foot switch equipped for operation convenience 

For added convenience and ease of use, the Film Heat Seal Tester is equipped with a foot switch. This allows operators to initiate the sealing process without having to reach for a button or control panel, which can be particularly useful in high-volume production settings. The foot switch is designed to be durable and responsive, ensuring smooth and efficient operation. This ergonomic feature helps to reduce operator fatigue and improve overall productivity.

Anti-scald design

Safety is a top priority in the design of the Film Heat Seal Tester. The machine features an anti-scald design to protect operators from burns and injuries. This includes insulated handles, protective guards, and temperature-sensitive materials that minimize the risk of contact with hot surfaces. The anti-scald design ensures that the tester can be used safely in a variety of environments, from laboratory settings to industrial production lines.
