The packaging of bread and wheat flower can best be done with a Bag Sewing machine such as the Newlong NP-7A as a portable help. Bread flower is a powderisch product that flows everywhere. When using a sewing machine stitching the bags wihout glue or heath but a simple thread. By folding the bag before stitching the bag you wil even get a more tight closure and the product cannot sift out of the bag.
