Most listings show a 4-gallon capacity for small drawstring bags; a smaller number of options are listed as 3-gallon.
Dimensions vary, but common listings show about 17 × 18 inches (often listed as 17 inches by 18 inches or 18" × 17"). Other listings report sizes around 16–17 × 16–17.7 inches.
These bags are offered in plain plastic, LDPE (Low-Density Polyethylene), and a biopolymer formulation used for compostable bags.
Some listings note post-consumer recycled content; at least one option is described as compostable/bio-based (plant-based) and carries BPI certification for biodegradability.
Listings emphasize drawstring closures and gripping drawstrings for quick cinch closure, easy tying, lifting, carrying, and secure removal to keep trash contained.
