Does plastic melt or burn?

First, there are two types of plastic: thermoset and thermoplastic.

Thermosets do not melt, they burn.

This is due to the crosslinks that create strong bonds between the polymer chains.

As more heat is put into the plastic, more bonds are broken and the material becomes more like a liquid and less like a solid..

Can Plastic bags catch fire?

Also the above said plastic materials start thermal degradation at a temperature above 270’C so the chances of plastic bag to catch fire is negative unless it is kept with some other flammable material which has auto-ignition temperature ~<45'C like white phosphorous.
