The monomer of a polythene bag is ethylene, which is a simple hydrocarbon with the chemical formula C2H4. During the polymerization process, these ethylene monomers link together to form polyethylene, the polymer that makes up polythene bags. Polyethylene can have different densities and properties depending on the specific polymerization process used, leading to variations like low-density polyethylene (LDPE) and high-density polyethylene (HDPE).
Theoretically - you could place a bag of water in a microwave and heat it that way. However - you would have to leave plenty of space to allow the water vapour to escape.
I believe biodegradable bags are the strongest because they are made to withstand pressure, weather changes, or just about any force. The strength and quality of these bags are made to last a lifetime.
