Flat Poly Bags 3″ x 18″ 2 mil 1000/CTN

• Size: 3 x 18 in
• Thickness: 2 mil
• Material: 100% Virgin LDPE
• Qty: 1000/Carton
• Closure: Open end — heat seal, tie, staple, or tape
• FDA/USDA compliant resin

The slim 3 x 18 in footprint is engineered for welding rods, filler wire sections, electrode bundles, and other long narrow products where standard bag widths create excessive material waste. Individual electrodes or small-count bundles slide in cleanly without the bag billowing or twisting. At 2 mil, the bag is strong enough to protect against moisture exposure that degrades low-hydrogen electrode flux coatings during storage. The open end can be heat sealed, tied, or stapled for clean closure on production or distribution lines. Made from 100% virgin LDPE resin meeting FDA/USDA specifications. Case of 1000 serves welding supply distributors, maintenance operations, and industrial fastener packagers.

Frequently Asked Questions

What welding rod sizes fit in a 3 x 18 in bag?

Standard stick electrodes in 9 in, 12 in, and 14 in lengths fit easily in this bag, including 1/16 in through 5/32 in diameter rods both individually and in small bundles of 2–4 rods. The 3 in width accommodates small bundled groups without straining the opening.

Does 2 mil protect moisture-sensitive electrodes?

Yes. LDPE poly bags provide a moisture vapor barrier sufficient for protecting stick electrodes during short-term storage and distribution. For long-term storage of low-hydrogen E7018 or similar moisture-sensitive electrodes, heat sealing provides a stronger barrier than tying or taping.

Can these bags be used for non-welding applications?

Yes. The 3 x 18 in size also works for paint brushes, drawing charcoal, incense sticks, fireplace matches, dowel rods, and other long narrow items in retail or industrial packaging.
