How do I choose the right size?

Measure your bin’s width and height before choosing a liner. Check the size guide and select the closest fit for your bin.

What does flat top liner mean?

A flat top liner has an open top without handles or drawstrings. It is designed to line bins smoothly and remove easily after use.

Does the star-sealed bottom help reduce leaks?

The star-sealed bottom helps distribute weight evenly and helps reduce leaks during everyday use.

How should I store compostable bags?
