These 12 x 36 flat poly bags are built for packaging challenges that standard bag sizes can't handle. The extra-long 36" depth gives you the room needed for tall, rolled, or elongated items, while the 4 mil virgin LDPE construction delivers over three times the impact resistance and twice the tensile strength of conventional poly bags. FDA food-contact compliant and Made in the USA, they're the reliable, heavy-duty choice for food service, industrial, and retail operations.

• 4 mil heavy-duty construction delivers over three times the impact resistance and twice the tensile strength of standard poly bags, protecting contents from tears, punctures, and rough handling.
• Extended 36" length accommodates tall, rolled, or elongated items that standard bags can't fit — eliminating improvised packaging and speeding up your workflow.
• 100% virgin LDPE resin ensures zero recycled-material contamination, maintaining the purity required for food, pharmaceutical, and sensitive product applications.
• FDA food-contact compliant material is safe for direct food contact, including bulk dry goods, fresh produce, frozen items, and deli packaging.
• Heat-sealable design allows secure closure to lock in freshness, prevent spills, and create tamper-evident packaging when required.
• Crystal-clear transparency keeps contents fully visible for easy identification, quality inspection, barcoding, and retail display.
• Made in the USA with rigorous quality controls, ensuring uniform thickness and consistent performance across every carton.

Where it works best:

• Food service: baguettes, sub rolls, long pasta, sausage links, meat cuts, bulk produce, deli items, and smoked fish.
• Retail & e-commerce: posters, rolled prints, fabric bolts, banners, blueprints, and oversized art supplies.
• Industrial & manufacturing: pipes, rods, dowels, tubing, metal bar stock, and other long structural or hardware components.
• Agriculture & nursery: flower bundles, plant cuttings, tree saplings, and nursery stock requiring extra-length protection during transport.
• Warehouse & fulfillment: shipping tubes, document rolls, rolled materials, and oversized inserts requiring consistent bag sizing.
• Floral & gift: tall bouquet wraps, gift bag liners, and oversized gift baskets needing protective coverage.

Solves key pain points: Finding a bag long enough for oversized or elongated products is one of the most common packaging frustrations in food service and industrial operations. Too often, businesses resort to double-bagging, folding, or wrapping with stretch film — all of which waste time, labor, and materials. The 12 x 36 format gives you the extra room you need in a single, purpose-built bag. The 4 mil wall handles the added weight, friction, and abrasion that longer, heavier loads demand, giving you one dependable solution across a broad range of large-format packaging needs.
