Flat storage bags commonly use double-seal zipper locks. Many plastic containers have snap-on lids with two‑latch or airtight seals, and some lids include vents for splatter‑resistant microwaving. Several items are marketed as leak‑proof or airtight.
Common multipacks include high counts such as 150‑count and 355‑count bags. Packaging is often clear and the bags feature double‑seal locks; some packs come in refillable or dispenser‑style packaging.
