Automatic packaging machines are generally divided into semi-automatic packaging machines and fully automatic charter machines. The automatic packaging machine is mainly used for automatic packaging of materials in food, medicine, chemical and other industries and plant seeds. Materials can be in the form of granules, tablets, liquids, powders, pastes, etc. The automatic packaging machine has the functions of automatically measuring, filling, bag making, sealing, cutting, conveying, printing production batch number, adding easy cutting, warning when there is no material, stirring and so on.

　　According to the requirements of product packaging, according to the required shape and size, we can get the packaging requirements with consistent specifications, but manual packaging cannot be guaranteed.

　　Some packaging operations that can be achieved by manual packaging are impossible to achieve by manual packaging, and can only be achieved by automatic packaging by machines.

　　It can reduce labor intensity and improve working conditions. The labor intensity of manual packaging is very high. For example, manual packaging of large and heavy products consumes physical strength and is unsafe; for light and small products, due to the high frequency and monotonous actions, It is easy for workers to get occupational diseases.

　　Conducive to the labor protection of workers For some products that seriously affect the health of the body, such as severe dust, toxic products, irritating and radioactive products, manual packaging will inevitably endanger health, while mechanical packaging can be avoided and can effectively Protect the environment from pollution.

　　It can reduce the packaging cost, and use the compression packaging machine to compress and pack, which can greatly reduce the volume, thereby reducing the packaging cost. At the same time, because the volume is greatly reduced, storage space is saved, storage costs are reduced, and transportation is facilitated.

　　It can reliably guarantee product hygiene. For example, food and drug packaging are not allowed to be packaged by hand according to the Sanitation Law because it will pollute the product. Automatic packaging avoids direct contact with food and drugs by human hands and ensures hygienic quality. Therefore, automatic packaging is suitable for various plastic composite films or plastic aluminum foil composite films, such as polyester/polyethylene, polyester/polypropylene, etc., which should have certain air tightness, pressure resistance and mechanical adaptability.
