The lamination process of PP Laminated Woven Bag is achieved through hot melt lamination technology, which is an efficient and reliable process method. First, high-quality PP woven fabric is selected as the base material. This woven fabric itself has excellent tensile strength and wear resistance, and is one of the ideal materials for making bags. Then, a layer of hot melt adhesive is applied to the surface of the woven fabric, which plays a key role as an adhesive.
Next, after a series of strictly controlled processing steps, the PP woven fabric and hot melt adhesive layer are fed into the hot melt laminating machine for processing. In this process, the machine will put the woven fabric and hot melt adhesive layer under a certain temperature and pressure, so that they come into contact with each other and fuse on the contact surface. By heating, the hot melt adhesive layer is activated, becomes sticky, and physically interacts with the surface of the PP woven fabric. This interaction results in a bond between the two, creating a uniform and tight coating.
This coating not only makes the bag waterproof, but also effectively enhances the bag's wear resistance and strength. Through this lamination processing technology, the PP woven fabric can be effectively reinforced, making the PP Laminated Woven Bag more durable and reliable during use. At the same time, because the hot melt adhesive layer can achieve good bonding with the surface of the woven fabric, this process also ensures the sealing of the bag, which can effectively prevent the contents of the bag from being affected by the external environment.
Hot melt lamination technology not only enhances the functionality of the bag, but also allows it to be customized according to customer needs.
