Our Products
We are leaders in the market for providing best range of Laboratory Heat Sealer
Heat Sealer is a consistent tool used to perform sealing on flexible packaging products and other thermoplastic materials using pressure and heat by maintaining high temperatures. A heat sealer is used to measure the heat seal performance of composite films, plastic films such as PP, PE used in packaging different food products such as milk powder, instant noodle, food, washing powder, and drugs.
Prestos Laboratory Heat Sealer is widely used in packaging and plastic industry. It is a machine used to seal products like thermoplastic materials, packaging material using heat. Heat sealing helps to join two different materials one of which consist of thermoplastic layer.
Heat Sealing is the process of sealing one thermoplastic material with another using pressure and heat together. The method of sealing utilizes a constantly heated sealing bar or die to apply heat to a specific contact path or area to weld the thermoplastic together. The laboratory heat sealer is used for multiple applications like heat seal connectors, films, thermally activated adhesives, foil sealing or plastic ports.
The temperature of the machine is adjustable. It is a fully pneumatic model that has a digital display and based on microprocessors.
The heat sealer is equipped with two jaws i.e. lower jaw and upper jaw. Both the jaws of the machine can be heated separately with different temperatures and controllers. Hence, it is possible to maintain the temperature of both the jaws separately. It is possible to enable or heat one heater at a time, and it is also possible to switch off one heater in between while performing the test. The instrument is used to seal the plastic sample at the predetermined heating temperature.
