Two Color Striped Blown Film Machine

Video

This two color striped blown film machine is particularly useful for making shopping bags, plastic packing bags, and table covers. It is capable of mixing different color stripe in the film product by simply changing the masterbatch, with two screws adjusting the mixing rate of the different materials.

Constructed out of 38 CrMoALA, the screw and barrel has undergone a 3-day nitriding process, affording it an unparalleled level of hardness.
