摘要:
Plastic drinking straws formed by extrusion from a multi-head extruder have at least partial layers of plastic on their outer and/or inner diameters, with the layers formed of scented and/or flavored plastics. These straws are generally used by children and the scents or flavors add to their novelty. They may be imprinted with spiral patterns produced by rotating the extruding straws and passing them against a rotating print wheel having its rotational axis inclined to the path of the straws.
