Sizes range from the standard “gallon” up to larger 2‑gallon and 2.5‑gallon options. Some listings also show metric or imperial equivalents — for example 3.78 liters and ounce measures such as 128 oz and 800 oz — across different packs.
Closures include double‑seal (double‑zipper) locks and slide/slider zippers. Some slider bags also call out reinforced tracks or click‑closed features for a more secure seal.
Most bags are described as made from plastic or polyethylene and labeled BPA‑free. Some reusable options explicitly state they are made without BPA, PVC, or phthalates.
Package sizes vary widely — examples in the listings include counts such as 8, 10, 12, 15, 30, 68, and 75.
Listed features aimed at preventing spills and freezer burn include double‑seal or double‑zipper locks, slide/slider zippers, reinforced seams, and other leak‑resistant construction details.
Variety packs list snack, sandwich, and one‑gallon sizes. A typical 15‑count pack is specified as 5 of each size.
