How to choose
- Gauge: 1 mil is thinner and more economical than 2 mil—use it for light, non-sharp contents. Step up to 2 mil, 3 mil or 4 mil when puncture resistance matters.
- Flat vs. gusseted: flat bags suit slim parts and literature; gusseted bags expand for boxed kits without jumping to a much larger face size.
- Size: measure the item’s length and width (and depth for gussets) and add room to close with tape, a heat sealer or a twist tie.
- Case packs: listed flat sizes and most gusseted sizes sell by the case (often 1,000 bags)—compare price per bag when mixing sizes.
- Cross reference: see the poly bag cross reference and the Uline 1–2 mil flat bag cross reference for size matches.
