The stretch film is heated by the stretch film packaging machine and the shape of the container is formed by the working principle of upper blowing and lower suction through the forming mold. The workers place the material in the material filling area, and the upper film area is covered by vacuum sealing. Packaging machinery that cuts transversely and longitudinally into individual products. 

Working Principle

The thermoforming stretch film packaging machine is a packaging equipment that does not require the user to customize packaging bags in advance. The stretch film is heated by the machine, and the shape of the container is formed by the working principle of upper blowing and lower suction through the forming mold. Workers perform the process in the material filling area. It is a packaging machine that lays out the material, vacuum seals the film in the upper film area, and cuts it into a single product by cross-cutting and longitudinal cutting; because the stretch film packaging machine does not need to customize the bag in advance, but is covered by the bottom film and the upper film. Some users call it a laminating machine or a four-side sealing packaging machine; the working principle of the stretch film packaging machine is simple, and it can also be seen from the name that the stretch film does not require customized packaging bags, and there is no requirement for the product packaging size. Therefore, the stretch film packaging machine has a wide range of applications; it is suitable for vacuum (inflatable) packaging of various raw and cooked products, seafood, medicinal materials, fruits, hardware components and other products. Extend product shelf life and freshness. Easy to store and transport. Because the product has the function of packaging after forming, it can highlight the advantages of the product and improve the grade of the product.

(1) Top film     
(2) Bottom film
(3) Thermoforming chamber---The bottom film soften under heat and is shaped as per the Die(mould)'s design by combined effect of compressed air & vacuum.
(4)  Loading area---Shaped cavities on the bottom film can be filled with materials manually or automatically.
(5) Sealing chamber---Air in the shaped cavities is exhausted through a vacuum tank, in the meantime nitrogen or another mixed atmosphere is flushed into the cavities, then the top film is applied & sealed to the bottom film under heat as per the sealing die's design.
(6) Cross cutting & longitudinal cutting units---Cutting knives separate individual packs from the sealed films.
