What is Heat Sealer?

A heat Sealer is a testing machine which is used to seal products, thermoplastic materials, and other packaging products using sufficient amount of heat.  Heat sealers are used to seal or join thermoplastic monolayers out of which at least one need to be a thermoplastic material and can join dissimilar materials too.

How sealing of the packaging films can be done?

Heat Sealing is the process of sealing one thermoplastic to another material or similar using a specific amount of pressure or heat. The direct contact method of sealing utilizes a constantly heated die or sealing bar that apply sufficient amount of heat to a particular contact area or path to weld the plastic materials firmly. The testing machine is used for various applications such as plastic ports, thermally activated adhesives, heat seal connectors, film media and many more.

Various Applications of Heat Sealing process

Heat Sealers are used to join different products that are used in various applications as well as in telecommunication and medical devices.

  • The sealing of a product using thermal adhesives are used to hold clear display screen on the consumer electronic products and for other sealed thermoplastic assemblies or devices where ultrasonic welding and heat staking is not an option due to assembly considerations.
  • Heat Sealers are also used in the manufacturing of the blood test films and many other test strip devices that are utilized in the field of medical science.
  • Bioengineering, food industries are also the important applications of Heat Sealers. The packaging products that are used in food industries are made up of thermoplastic films, foils, and laminates; heat sealer is used in food processing industries to seal the packets of food products efficiently to ensure the freshness and hygiene of the product.

Types of Heat Sealers

Numerous types of Laboratory Heat Sealer that are used for different applications. Some of them are mentioned below:

  • Hot Bar Sealer – These types of sealers equipped with irons, heated bars, dies, etc. The temperature of the bar is maintained at a constant temperature which directly contacts with the material to create a bond between two substrates. The dies, irons and bars have different configurations that are delivered to the customers as per their application’s requirement. 
  • Band Type or Continuous Heat Sealer –These types of sealers is assembled with the moving belts over the heating elements.
  • Laboratory Heat Sealer – The testing instruments is used to seal the bags that are used in packaging industries.  The device is used to ensure the intactness of the plastic bags and other packaging bags that are used to back different consumable and non-consumable goods.

The manufacturer of heat sealer offers a broad range of Heat Sealer for multiple applications to fulfill the requirement of packets sealing.
