yes . hdpe is hard material. LDPE is soft. But I think machine compatibility should be checked.

ACtually you can use LD or HD for same mold. The difference is bottle sturdiness. As i Know if Blow molding machine is used then you can use same mold for both the material. Material grade is important.we can use LD & HD both material for same bottle mold.we can use both material for cap that is made by Injection technology. but the material grade is different. LD, HD & PP are all PE. PP is harder than hd & LD.
