Horizontal heat sealer for coffee packaging
Heat sealers help protect the coffee bags’ contents from external elements and possible tampering.
Heat sealers use wires that are triggered when a heat-resistant bar is pressed on the opening of a coffee pouch or bag. When the bar is closed, an electrical current heats up the wires using electric light.

What is heat sealing?
Heat sealing was developed to help protect a package’s contents from external elements and possible tampering.
Typically, heat sealers use wires that are triggered when a heat-resistant bar is pressed on the opening of a coffee pouch or bag. When the bar is closed, an electrical current heats up the wires using electric light.
These wires heat up almost instantly and melt the package’s material while the bar presses the two sides together, effectively sealing it. Sealing packages keeps the coffee in a sterile and impenetrable environment until consumption.
Important to realise is the seams in packaging can often be a weak point, allowing oxygen and moisture to enter, effectively spoiling the beans. This means coffee must be sealed without creating pinholes, punctures, or wrinkles in the packaging.
Some heat sealers also vacuum air out of a package before sealing it to prevent oxidation. However, this is less common with polypropylene (PP) or polyethylene (PE) coffee bags, as they are porous and less suited for long-term product storage.
