Blueprint & Technical Drawing Poly Bags — 18 x 24 in., 3 mil LDPE
These flat poly bags are purpose-sized for architectural drawings, engineering blueprints, and large-format technical documents at the standard 18 x 24 inch format. The 3 mil wall provides firm protection against moisture, abrasion, and folding damage during jobsite transport, archival storage, and client delivery. Open-end design allows rolled or flat documents to slide in and out without creasing.

Material Notes
Manufactured from 100% virgin Low Density Polyethylene (LDPE) resin. LDPE at 3 mil provides a stiff yet flexible moisture barrier well suited for flat document protection. The clean, unrecycled resin minimizes surface irregularities that could mark or transfer to ink-coated print media. All gauge specifications are nominal.
Use Case Notes
18 x 24 inches is a standard architectural drawing size (ANSI C). These bags fit this format with margin for clean handling. For rolled drawings, the 18-inch opening accommodates standard tube diameters when the bag is used without rolling. For bundled sets, multiple sheets can be stacked flat.
Common Questions
Q: Will these bags fit standard 18x24 architectural drawings?
A: Yes. The bag dimensions are nominal; the interior accommodates standard ANSI C (18 x 24 in.) drawings flat with room for easy insertion and removal.
Q: Can I use these bags for rolled drawings?
A: Yes. The 18-inch open end accepts most rolled 18x24 drawing tubes. For large-diameter rolls, verify the tube diameter fits within the bag opening before ordering in bulk.
Q: Are these bags reusable for archival storage?
A: Yes. Virgin LDPE does not off-gas or become brittle under normal storage conditions, making these suitable for long-term archival use when properly sealed.
Why Buy
Packed 500 per carton, these bags support high-volume document handling for architecture firms, engineering offices, print shops, and municipal plan rooms. The 18x24 format eliminates the need to source oversized bags and trim or fold drawings to fit, preserving document integrity from production through final delivery.
