Good morning Jai

Polyethylene is a plastic, impervious to almost all chemicals.  It what most
of the household containers such as wash basins, icebox storage containers,
etc., are made of.  When I had my PC board shop I had large 7-gallon tanks of
polythylene for sulfuric acid pre-clean, electroless copper, plating and
etchant.  You won't need tanks near that big.  A helpful method of heating is
to just place your etchant tank in a larger container filled with very hot
water.
