A · Paper Roll Holder
The process begins with the loading of a large paper roll onto the machine. This role serves as the primary material for bag production and is typically made of kraft paper or other environmentally responsible materials.
· Printing Unit (Optional)
Some SOS paper bag making machine models have a printing unit allowing custom branding and design on the bags. It is set for multi-color printing and precise design.
· Web Guiding System
This ensures that the paper roll is accurately aligned as it moves through the machine, as well as maintains the proper dimensions of the bags.
· Rotary Die-Cutting Unit
The die-cutting unit is responsible for cutting the paper into the desired shape and size for the bags. It uses rotary dies to cut the paper, ensuring consistent and accurate results precisely.
· Gluing Unit
The gluing unit applies adhesive to specific areas of the paper, allowing for the folding and sealing of the bags. The type of adhesive and its application method can vary depending on the machine's design.
· Bag Forming Section
This section transforms the flat paper into a three-dimensional bag shape. It folds, creases, and seals the form to create the distinctive square bottom and open-square top of SOS paper bags.
· Conveyor System
A conveyor system is often integrated into the machine to transport the completed bags to the collection point. This ensures a continuous and efficient production process.
