With solvents. The kind of solvent depends on the "plastic" involved. Polystyrene dissolves in benzene or toluene

Polyurethane (not the thermoplastic which is insoluble in most solvents) can dissolve in acetone.

Polyethylene is resistant to most organic solvents.

Styrofoam will dissolve in the isopropanol solvents used in some glues. This can be helpful or hindering when working with arts and crafts.
