What a load of nonsense. Aluminum is a great conductor of electricity. Not as good as copper, but good enough that it gets used as the conductor for high tension power transmission lines. Additionally, you’d need a far more powerful radio than a cellphone would contain to melt a plastic bag. A cellphone radio is what, 3W? You might threaten the bag if you focused all that energy in a dime sized spot on the bag, but a cell radio is intentionally a roughly isotropic radiator.
