The working principle of the flip fruit box and lunch box equipment is reported in the article

Flip over fruit box is a packaging used to protect and store fruits in a convenient and attractive way. Packaging is usually made of plastic and aims to protect fruits from damage and pollution. Thermoforming Food contact materials production equipment produces plastic flip boxes for packaging fruits.
The Food contact materials production equipment is a multifunctional and efficient machine, which aims to produce Food contact materials quickly and easily. This machine is suitable for PET, PVC, PS, PLA materials. The following is the working principle of the Food contact materials manufacturing machine.
The Thermoforming process involves heating a thermoplastic material (where PET plastic will be used) to a plastic temperature. Next, after installing the PET sheet, check if the temperature has reached the set value, and check the air pressure and vacuum pressure. After confirmation, operate in the PLC operating system, click to enter the molding interface, and select automatic mode. Then the machine starts moving the heating furnace to its working position, waiting for the sheet to arrive. The heating furnace raises the temperature inside the container to a certain temperature, causing the raw materials to melt. Then, the melted raw materials are poured into the mold to solidify and form the desired shape.
Once the plastic is heated and formed, it will be sent to a cutting station where cutting tools are used to cut flip fruit boxes according to the customer's specifications. This cutting tool can accurately cut complex shapes. Afterwards, we arrived at the stacking station and used a robotic arm to stack the finished products, which were then transported out by a conveyor belt. Finally, use a waste machine to collect waste.
