Material feeding

The flat plastic film or sheeting is fed into the bag making machine through a series of rollers and guides. The material is typically fed from a roll of plastic film or sheeting.


The bag making machine uses heat or ultrasonic sealing to seal the edges of the plastic film or sheeting together to create a tube of material.


The tube of material is then cut into individual bags to the desired length. The cutting process can be done using a variety of methods, such as rotary cutters or guillotine cutters.

The operation of a bag making machine can vary depending on the specific type of machine and the type of bags being produced. It is important to follow the manufacturer’s instructions and safety guidelines when operating a bag making machine to ensure safe and efficient operation.
