It depends on the plastic. Because it is an ester, PET (polyethylene terephthalate) is easily hydrolysed by sulphuric acid. The hydrocarbon plastics such as polyethylene and polypropylene are unreactive to most acids and cold sulfuric is OK but hot acid is not recommended. Highly oxidising acids are not recommended for PE or PP even when cold.
