The film packaging machine's film roll is the main part of the machine, used to provide the plastic film required for packaging. The heater is used to heat the plastic film to an appropriate temperature, making it flexible and malleable. The conveyor belt is used to transport products to the packaging location. A press is used to press plastic film onto the product, making it tightly adhere. The sealing mechanism is used to seal the edges of the plastic film together to ensure the sealing of the packaging.
