Sagar fast food - Hot food in plastic container

I ordered food like paneer butter masala from swiggy but my concern is hot gravy getting transfer into plastic container. Over heat gravy melting in plastic. Please ask every restaurant to stop doing like this. Each n every body ordering food and getting delivered with plastic cover or small container. It will affects human body like it releases dioxins, phthalates, vinyl chloride, ethylene dichloride, lead, cadmium and other toxic chemicals. It can leech many of these harmful chemicals into the water or food it's being used to contain, which is how those chemicals get into our bodies
