Müllsack vs. Mülltüte vs. Abfallsack
While all three words translate to trash bag or garbage bag, the choice depends largely on the size of the bag, its material thickness, and the level of formality. Mülltüte is for small indoor bins, Müllsack is for large heavy-duty needs, and Abfallsack is the formal technical term.
Müllsack
A2This refers to a large, sturdy trash bag, typically with a capacity of 60 liters or more. A Müllsack is usually made of thicker plastic (often black or blue) and is used for heavy loads, outdoor bins, or gathering the contents of several smaller bags.
