Our toothpaste packaging line is normally applied in products including food, cosmetic, pharmaceuticals, household chemicals, and so forth. This cream packaging machine normally uses flexible tubes as toothpaste packaging materials. The flexible tube can be filled with optional materials such as creams, gels or viscous fluids. Then, it is required to undergo hot melt lamination, printing, trimming and shaping operations to form the final product. In this process, a conveyor is used to automatically send these tubes into a box packing machine. It is paired with a photoelectric sensor that provides non-contact accurate detection of toothpaste as well as other products.
