Plastic or Plastics? Singular or Plural?

Hi! I am confused when we mention something plastic, we use singular or plural? Because sometimes it is singular and sometimes it is plural but they indicate the same thing. For example:

(1)Seaweed has a big potential to place single-use plastics.
(2)Underwater seagrass in coastal areas appear to trap plastic.

are "plastic" and "plastics" interchangeable?
