Food container thermoforming molding is a process of producing food containers from plastic sheets using a thermoforming machine. This process involves heating a plastic sheet until it is soft and pliable and then shaping it into the desired container shape using a mold or a series of molds.
The food container thermoforming molding process typically involves the following steps:
Sheet heating: The plastic sheet is heated until it is soft and pliable. This can be done using a variety of heating methods, including radiant heaters, convection ovens, and infrared heaters.
Sheet forming: The heated plastic sheet is then stretched and formed over a mold or series of molds using a vacuum or pressure forming process.
Trimming: Once the container has been formed, excess plastic is trimmed away from the edges of the container.
Stacking and packaging: The finished containers are then stacked and packaged for shipping and distribution.
