Because the shape of the bags is pillow shaped, it is usually called pillow packing. Pillow type packer can be roughly divided into pillow type and longitudinal type. The packaging process is carried out horizontally, so it is called pillow packing machine. It is mainly used for the packaging of solid objects and multiple items. On the other hand, the installation of packaging engineering from top to bottom is called vertical packaging machine. The vertical packing machine is used for the packaging of rice cakes, sweets, liquids, powder bags and fluids. Various kinds of packaging products can be seen in the market, and there are various forms of packaging. Many pillow packing products are packaged by pillow packing machines.
What are the basic knowledge of pillow packing machine?
Pillow packaging machines were developed in the United States in the 1930s. It has been 46 years since they were actually manufactured in Japan. These packaging machines have been put into various markets and have been widely used.
Packing process of pillow packing machine
According to the packaged products, the size of the packaging film was set up beforehand. As the main packaging material, plastic film is used, sometimes using paper and aluminum foil as the substrate.
The membrane is sent from the feeding roller and a barrel shaped bag is formed in the bag making device. Then, the two ends of the membrane are palm-closed, and heat and pressure are applied to the two ends of the membrane at the central sealing part, and thermal adhesion (thermal sealing) is carried out. By means of a supply and transfer device arranged in the front section (supply section) of the bag maker, the packages are continuously inserted into the tubular membrane at certain intervals. The packed goods in the cylindrical film move forward at a certain interval by pressing the conveyor belt up and down. The terminal seal (also known as top seal) device heats up the middle film between the packed goods and the packed goods. At the same time, the cutting machine cuts the packed goods and ends the packing process. Pillow type packaging machine has carried out a series of operations.

Most machines consist of the following parts: the "Supply and Transport Unit" for handling packages, the "Membrane Supply Unit" for supplying packaging materials (membranes), the "Bagging Unit" for making bags with membranes, the "Middle Seal Unit" for the central part of the two ends of the film after being heated and adhered to the bag, and the "Product Transfer Unit" for moving packages forward. "Bottom seals (end seals) cut while heating and adhering to the film of the packaged goods, and finally the packaged goods are transported to the"discharge belt"of the next process. According to packaging machinery manufacturers, the design and shape are different, but the basic composition is the same.
