To seal the top part of the coffee bag, use a heat sealer.
After filling the bag with coffee beans, hold the opening together, then close it off with the heat sealer.
The sealer should not be set to a very high temperature. In case it cannot be adjusted, put a baking sheet on the surface, then use the sealer.
This way, the bag will not be burned during the proccess.
