Market Applications: Selecting the Right Process Heater

Heat Sealers

Heat sealers, also known as heat seal machines or impulse sealers, are used to seal various types of packaging materials, such as plastic bags, pouches, and films, by applying heat to melt the material together. They bond packaging materials together, creating airtight seals that protect products from contamination and spoilage. Heat sealers typically consist of a heating element, a sealing bar or jaw, and a pressure mechanism. Cartridge heaters and coil heaters are commonly employed in heat sealers to provide the precise heat required for sealing various packaging materials.

Here's how they work in a packaging application:

Heating element: The heating element, often made of nichrome wire, generates heat when electricity passes through it. This heating element is usually located within the sealing bar or jaw.

Sealing bar or jaw: The sealing bar or jaw is the part of the heat sealer that presses the packaging material together to create the seal. It is usually made of a heat-resistant material such as aluminum or stainless steel.
