Design and Material Selection: Select materials such as white cardboard and kraft paper according to requirements, and determine the size and structure.
Printing and Surface Treatment: Use offset printing for patterns, and apply lamination, hot stamping, or UV coating to enhance the texture.
Die-cutting and Box Gluing: Cut the shape using a die-cutting machine, and then use a box-gluing machine to complete the forming operations such as gluing the bottom and sides.
Folding and Forming: Fold the paper in half to create creases on the sides and bottom of the bag, forming the bag structure.
Adhesion and Fixing: Use double-sided tape or white glue to glue the sides and bottom, ensuring a strong and leak-proof seal.
Decorative Handles: Punch holes at the bag opening to insert a rope, or attach decorations such as bows to complete the production.
Post-processing and Quality Inspection: Includes steps such as punching holes, threading ropes, and reinforcing with rivets, followed by quality inspection and packaging.
