The paper used for making paper bags is typically in the form of large rolls. The rolls are unwound, and the paper is cut into sheets of the desired size for the bags.
The paper sheets are then folded and creased to form the basic structure of the bag. This process may involve machinery that automates the folding and creasing steps.
Hot Melt Adhesive is applied to specific areas of the paper to create secure bonds and ensure the bag’s integrity. The adhesive is usually applied to the flaps, seams, and edges of the paper bag. It helps hold the bag together and prevent it from coming apart.
Water-Based Adhesives are also used in paper bag manufacturing industry. Feel free to check it out.
