Typically, the machine head employs methods such as stitching, heat sealing, or gluing to close the bags. Each method has its advantages depending on the type of bag and the contents that need protection. For example, heat sealing is particularly effective for plastic bags as it provides a strong and waterproof closure. On the other hand, stitching is suitable for fabric bags, delivering durability and resistance against tearing during transport.
