I have not tried CuCl in HDPE long term, but i can tell you that  
concentrated HCl will form salts or something on the outside of a HDPE  
chemicals bottle. H2O2 will make the inside of the HDPE bottle brittle.

In finished CuCl the concentrations are much lower, so it may be fine. If  
you keep CuCl in a thick walled PET bottle it will also form salts or  
crystals on the outside.
