Publishers, printers, and direct-mail distributors use this size for poly-wrapping oversized printed pieces prior to shipment.

Features

• 100% virgin LDPE resin — no recycled content
• 3 mil nominal gauge — heavy-duty construction for large, weighted items
• Open-top design — compatible with heat sealing, tying, stapling, or tape closure
• High transparency for quick visual identification of contents during staging
• Manufactured with durable bottom seal or extra-strong side weld

Material Notes

LDPE (Low Density Polyethylene) at 3 mil delivers the combination of flexibility and puncture resistance needed for heavier or irregularly shaped goods. The virgin resin formulation is FDA and USDA compliant. LDPE’s moisture resistance makes these bags appropriate for direct-mail poly-wrap applications and warehouse storage of goods subject to humidity variation.

Use Case Notes

The 14″ x 20″ footprint is proportioned to accommodate large-format B2B catalogs and coffee table-sized books with room to spare for easy insertion. Direct-mail and fulfillment operations use the 3 mil thickness to protect heavy printed materials from tearing during automated handling. Industrial distributors use this size for flat hardware assemblies, brake pads, and medium auto parts that need individual moisture and contamination protection before kitting into a master carton.

Common Questions

Q: Are these FDA compliant for food contact?
A: Yes. These bags are manufactured from 100% virgin LDPE resin that meets FDA and USDA specifications for direct food contact.

Q: Is 3 mil the right gauge for heavy catalogs?
A: For most trade catalogs and books up to 5–6 lbs, 3 mil provides sufficient protection. For heavier items or palletized distribution where bags may be subject to abrasion, 4 mil may be more appropriate.

Q: Can these be used with automated poly-wrap equipment?
A: Yes. Open-top flat poly bags are compatible with most manual and semi-automated packaging lines. Verify bag dimensions against your equipment’s feed specifications before use.

Why Buy

At 500 units per carton, these 14″ x 20″ x 3 mil LDPE bags represent a practical mid-volume stocking quantity for publishers, print distributors, and industrial parts operations that need oversized, heavy-gauge flat poly at a predictable cost. Virgin resin construction ensures batch-to-batch consistency in clarity, seal strength, and gauge — critical for operations where packaging failures create downstream rework costs.
