What are the differences between PE standard tube and printing tube and screen printing tube?

PE label tube is printed on the PE label first and then pasted on the tube. The advantage is that the printing effect is good, but the label area is limited, and may wrinkle, and the cost is high.
Printing tube usually refers to dry offset printing (Dry Offset), which is used to transfer ink to cosmetic plastic tube by rubber roll once after tube embryo is made. The advantages are low cost, but the number of printing colors is limited.
Screen offset tube, as its name implies, is to use screen printing to print tubes, the advantage is that the ink layer has thickness, touch, feel high-end!
