|How to close a paper bag
After the bag is filled weighed, and ready for closing, the operator should first bring the 2 sides of the bag together. Next, fold or "break" the top of the bag sharply over contents. Bring the top of the bag upright into closing position. The sides will be close together, smooth, and wrinkle-free. Proceed with the sewing operation, but sewing no more than two inches down from top of bag.
If sifting is a problem, merely tuck in the inner ply tightly over contents and proceed to sew remaining plies.
Note: Sufficient top space is necessary to properly close any bag.
