Bag thickness is written in millimeters in our tables (0.030 = 30 µm). Light office waste is fine at 12–20 µm in HDPE; kitchen and mixed waste sits at 20–30 µm in LLDPE; construction debris and branches call for 40–80 µm heavy-duty bags.
Capacity in liters should match the bin, with 10–15% extra height for tying. Our code tables list width and length so you can check the fit against your bin dimensions before ordering.
