IMPORTANT: If the heat applied to the teabag is not hot enough the bag will not seal properly or will unseal during the steeping process.
Turn iron onto cotton or hottest setting. On a counter top or other flat surface, place a clean cloth / towel that is suitable to iron on, and then place the teabag on the cloth. Press iron down with slight pressure on the open edge for approximately 5 – 10 seconds. Make sure the open end is sealed with an edge of approximately 0,5mm in width.
The flat iron must be on a hot setting. Place the bag between the heated flat iron and hold in place 5 – 10 seconds (depending on the temperature). You might need to seal it again if your flat iron isn’t hot enough. Make sure the open end is sealed with an edge of approximately 0,5mm in width.
