Most listings are for either 13‑gallon tall kitchen bags or 4‑gallon small bags, so capacities typically range from 4 to 13 gallons.
Listings consistently list plastic materials—most commonly polyethylene (also shown generically as “plastic”).
Thickness in the listings ranges from 0.5 mil up to 0.9 mil, with many 13‑gallon bags around 0.82 mil and some smaller bags at 0.5 mil.
Pack counts vary by product; example listings range from about 30 bags up to 100 bags per pack.
13‑gallon tall kitchen bags are commonly shown with drawstring closures, while 4‑gallon small bags are more often listed with ties or open‑top designs.
