This machine is suitable for automatic packaging of various paste or viscous products such as tomato sauce, ketchup, mayonnaise, peanut butter, honey, shampoo, and chemical pastes. The round hopper with a stirring and heating system prevents material from solidifying or separating during the packaging process. The gear pump provides precise and consistent dosing for thick liquids. The back-sealing mechanism produces neat and secure bags. This machine is widely used in the food, cosmetic, pharmaceutical, and chemical industries for small to medium-scale paste packaging applications.
