Thermoforming vacuum packaging is an internal packaging method using two rolls of film. Its process consists of heating to form bottom film into tray-like cavities, loading products onto them and sealing in a vacuum with the top film.
Workflow：
Sheet Feeding: Thermoplastic sheets are fed into the thermoforming machine from a roll or pre-cut sheets. The sheet is advanced through the machine using rollers or a conveyor system.
Heating: The sheet passes through the heating section where it is heated to a pliable temperature. Heating can be achieved through infrared heaters, radiant heaters, or other heating elements.
Forming: Once heated, the sheet moves to the forming station where it is positioned over a mold or into a mold cavity. Vacuum or pressure (or a combination of both) is applied to shape the heated sheet according to the mold contours.
Cooling: After forming, the packaging moves through a cooling station where cool air or water is applied to solidify and cool the formed packaging.
Trimming: Excess material is trimmed away from the formed packaging using cutting dies or knives that are part of the machine.
Discharge: Finished packaging is either stacked or conveyed out of the machine for filling and further processing.
Thermoforming packaging machines are versatile and efficient, capable of producing a wide range of packaging solutions for various industries including food, medical, electronics, and consumer goods. Their automated processes ensure consistency and reliability in packaging production while optimizing material usage and production speed.
