I completely agree with the suggestion. "Plastic" is a popular synonym for polymer but actually describes a specific behavior. One good thing is that the word "plastic" is typically associated with synthetic polymers and allows distinction from biopolymers, which form a very broad class of their own and perhaps deserve their own tag?

Aside: other useful terms that encompass "polymer" and may deserve their own tag are "macromolecules" and "colloid". "Colloid" in particular captures explicitly a connection between spatial dimension and physicochemical behavior which is lacking in "polymer". "Colloid" overlaps with "nanotechnology" but is largely distinct. It is however a somewhat old-fashioned term. Alternatives include "mesoscopic materials" and "soft matter" but these are less well known.
