What are flat poly bags? Flat poly bags are open-ended polyethylene bags with a sealed bottom, designed for packaging, shipping, and storage of a wide variety of products. They offer economical protection from moisture and contamination while maintaining product visibility. What mil thickness do I need for mailing magazines? 1.5 mil is ideal for standard magazines, catalogs, and printed materials under 2 pounds. This lightweight gauge provides adequate tear resistance and moisture protection while minimizing postage costs. Heavier publications or multi-item bundles may benefit from 2 mil or thicker bags. Can these bags be heat sealed? Yes, LDPE flat poly bags are compatible with impulse heat sealers, hand sealers, and automated sealing equipment. Heat sealing creates a secure, tamper-evident closure ideal for protecting contents during shipping. Alternative closures include twist ties, adhesive tape, or staples for quick-access applications.
