Plastic vials are often small (around a few inches tall). They have straight sides, with the mouth being nearly the same width as the rest of the tube. They can have rounded or flat bases. Plastic vials can be printed using screen printing, printed labels, or shrink sleeves.
They can be made from a variety of plastics, often HDPE or PP. They can close with a screw cap, or even a plastic plug or cork.
