How to seal the coffee bags?
After we fill in coffee bean or coffee powder inside our coffee bags,
How to seal the Coffee bags?
We current have 2 methods:
First, use a ziplock close, and Second use a tin tie.
You simply roll the tin tie and bag downwards and fold its edges over each side of the bag, As tin ties allow the coffee bag to completely open at the top, they make scooping and measuring coffee easier, However, they don`t provide an airtight seal, meaning that they can still let oxygen in or out.
So we need a heat sealing machine to seal the coffee bag at the top. After heat sealing at top of the bag, the Coffee bag will be totally airtight.
