A manual sealing machine is a type of sealing equipment used for packaging products. It is a compact and portable device that is commonly used in small-scale food packaging, retail stores, and other industries that require a simple and efficient method of sealing bags or containers. The manual sealing machine works by heating a seal bar, which is then pressed onto the bag or container to melt and seal the plastic material. The manual design allows for easy and efficient operation, as the operator uses their hands to apply pressure to the seal bar and secure the seal.
