Flat Poly Bags 34″ x 48″ 4 mil 100/CTN

Heavy-duty 4 mil LDPE flat poly bags in a 34×48 in. format provide durable protection for large flat components including cabinet doors, drawer fronts, furniture panels, and fabricated parts. The extra gauge resists puncture and tear during transit, stacking, and warehouse storage better than standard 2 mil alternatives.

Specs: 34×48 in. | 4 mil | LDPE | 100/carton | FDA compliant

Applications

• Cabinet door and drawer front packaging for kitchen and bath cabinet manufacturers
• Flat furniture panel protection for RTA furniture producers and wholesale distributors
• Auto body panel and hood transit bags for automotive parts distributors and OEM suppliers
• Large fabricated sheet metal and stamped part protection for industrial manufacturers
• Architectural millwork and door blank protection for building products distributors

Features

• 100% virgin LDPE resin — no regrind, consistent 4 mil nominal gauge for predictable sealer performance
• 4 mil wall provides heavy-duty puncture and abrasion resistance for stacked panel handling
• Bottom-seal or side-weld construction delivers full seam strength under load
• Open-end format — heat seal, tie, staple, or tape closed depending on the application
• 100 bags per carton — suitable for cabinet and panel production line workflows

Material Notes

LDPE (Low Density Polyethylene) at 4 mil is rated as a heavy-duty gauge for flat poly bags. The increased wall thickness provides meaningfully better puncture resistance compared to 2 mil or 3 mil, making it appropriate for panel goods that are stacked, banded, or palletized during shipment. FDA compliant virgin resin meets FDA and USDA specifications for indirect food contact, though primary use for this format is industrial panel and component protection.

Use Case Notes

The 34×48 in. format accommodates most standard cabinet doors (typically up to 30 in. wide) with room to spare, and flat panels up to approximately 47 in. in length. For doors with applied molding or raised profiles that increase thickness, confirm the bag opening is sufficient before loading to avoid stretching the film across the panel face.

Common Questions

Q: Will this gauge prevent scuffing on finished cabinet surfaces?
A: The 4 mil LDPE film provides a moisture barrier and surface scratch protection during transit and storage. For high-gloss or veneer surfaces, consider interleaving foam or tissue before bagging for added surface protection.

Q: Are these FDA compliant?
A: Yes. Produced from 100% virgin LDPE resin meeting FDA and USDA specifications for indirect food contact use.

Q: What is the case quantity?
A: 100 bags per carton.

Q: Can these be heat sealed?
A: Yes. Standard impulse sealers and band sealers work with 4 mil LDPE. Higher dwell time or temperature settings may be required compared to lighter-gauge bags.

Why Buy

Heavy-gauge flat poly bags at this size are used in demanding cabinet and panel production environments where bag failures during stacking and transit cause rework and customer complaints. Our bags are produced from 100% virgin LDPE — not regrind — which delivers consistent gauge performance and reduced seal failures compared to off-grade alternatives.
