linear low density (lld) trash bags are strong, flexible and highly resistant to
puncturing and tearing. They are ideal for kitchen trash,
construction debris or trash that includes glass, metal, wood,
cardboard or irregular shaped items.
high density (hd) can liners are a more cost-effective option. Manufactured
from different resins, they are thinner than Linear Low
Density bags and are not as puncture resistant, yet they can
carry very heavy loads.
The 30" x 37" trash bag fits most 20-30 gallon trash cans. Shopping by Dimension works when you know exactly which size you need. If you are unsure, you can simply choose to shop by Gallon size instead. It is always best to take the next size up (and have some extra overhang) if you are doubtful of a perfect fit.
