Question:

What are plastic bags made out of?

Obviously I know its from plastic, but where does THAT come from?

Answer:

1Polyethylene mostly but relay any thermoplastic. 2oil.
plastic bags are made up of polyethelene or polymers
plastics are polymers that can be molded or shaped, usually by heat or pressure. plastics can be either thermoplastics (can be melted and formed again and again) or thermosets which, once formed, are destroyed rather than melted by heating. composition can vary depending on the type of plastic, but most prominent are Hydro-Carbon (Hydrogen and Carbon)
