<p>When a waste plastic such as, e.g., a waste container/package made of a plastic or other general plastic product waste, is used as a plastic material to be recycled, 0.1-40 wt.% acid acceptor is mixed with the plastic material to be recycled, the acid acceptor being in the form a masterbatch mixture with a base resin. The base resin preferably is an ethylene/ethyl acrylate copolymer or low-density polyethylene. The acid acceptor may comprise any one or more of magnesium oxide, hydrotalcite, calcium carbonate, magnesium carbonate, calcium hydroxide, and magnesium silicate. Thus, generation of hydrochloric acid can be inhibited when a waste container/package made of a plastic or other general plastic product waste is used as a plastic material to be recycled or is formed into pellets.</p> |
