LDPE , HDPE, LLDPE
Hefty sandwich bags are made up of polythene.
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.

No. Technically it is not possible.
it may be more echo friendly to use material bags but you can also reuse polythene bags so whats the point it is easy to carry. it is cheap and best.
