There are two kinds of PP/PS sheet extruder in our company, one is single layer can make one color sheet, the other is double-layers making two colors sheet.

For customers who want to make both single color and two colors sheet, there is no need to buy two types of sheet extruder, one set of single-layer PP/PS sheet extruder is enough,because it can also produce two colors sheet, just to put the same sheet material in two feeding barrel.
