HDPE is a suitable plastic for a mop bucket. Select 3 reasons why from the list below
HDPE is chemically resistant so won't degrade or react to detergents or bleach
Rigid material that won't shatter
Can be moulded to a complex shape to allow two parts to be joined together
Low melting point so can be easily injection moulded

Softens (plasticises) at a low temperature
Durable
Detail can be added to the container to lock neatly together to ensure safe transportation of food
