Printed Kraft Sack Manufacturer Paper sacks are the packaging of choice for a wide variety of products such as flour, sugar, animal feed, and cement. They are also commonly used for packaging nuts, coffee, and rice. The paper sack is a packaging staple because it is strong, stackable, and relatively inexpensive. A paper sack is made from Kraft paper, which is a type of paper made from wood pulp. The wood pulp is treated with chemicals and then pulped to make a strong, durable paper. Kraft paper is brown in color and has a distinctively earthy smell. The paper sack is usually manufactured by first creating a flat sheet of paper. The sheet is then cut into a rectangular shape and folded into thirds. The bottom of the sack is glued or stapled shut, and the top is left open. The sides of the sack are then stitched or glued together. Paper sacks can be printed with company logos or other designs. This makes them an ideal choice for packaging products that need to be branded. Paper sacks are also recyclable, which makes them a more environmentally-friendly option than plastic bags.
