Firstly, choosing good quality plastic sheet, we choose various color of sheets, such as transparent, white, black and so on. Then, we put the roll of plastic sheet in the semi automatic or full automatic machine.
After putting the roll of plastic sheet in the machine, the sheet will be heated to let it be more soft, then the heated sheet will be more easier to mold. Then the moulds form the plastic sheet to be various shapes.
Once plastic sheet is formed to shapes, the machine demold the formed products. Then formed items will be ran to the cutting machine to cut the edge material. In the end, we produce disposable plastic salad containers.
