Material Notes

Made from 100% virgin Low Density Polyethylene (LDPE) resin. 3 mil gauge provides significant resistance to moisture, abrasion, and surface scuffing — appropriate for documents and prints requiring dust-free, moisture-resistant storage. FDA/USDA compliant for incidental food contact.

Use Case Notes

20″ x 24″ is a standard footprint for full-size architectural blueprints when folded once, large retail posters, and wide-format print stock. The 3 mil gauge is preferred in print shops, architecture firms, and map distributors who need puncture resistance without the stiffness of heavier gauges. At 250 bags per carton, this pack size suits medium-volume fulfillment or job lot requirements.

Common Questions

Q: Can these bags be heat sealed?
A: Yes. Standard impulse sealers and bar sealers work with 3 mil LDPE without adjustment.

Q: Are these bags anti-static?
A: No. These are standard LDPE poly bags without anti-static treatment. For electronics or static-sensitive materials, specify static-shielding or anti-static bags.

Q: What does FDA/USDA compliant mean?
A: The resin used meets FDA and USDA specifications for incidental food contact. The bags are not FDA-approved devices.

Why Buy

250 per carton, 3 mil construction, and a 20″ x 24″ open-face format make these a practical standard stock item for print distributors, architecture supply houses, and wholesale packaging operations that regularly ship or store large flat documents. The FDA/USDA compliant resin also qualifies these for food-adjacent applications when needed.
