Material
HDPE
Opaque, tough, chemically resistant. The household default.
What It Is Good At
Acids, alkalis, bleach, surfactants. Cheap per gram and forgiving in a drop test.
Where It Stops
No clarity, and some oils permeate the wall. Not a premium cosmetic look.
Typical Use
Detergent, bleach, shampoo family sizes, refill packs.
