Buying Guide

Pick the right material

Poly bags are common for mail and shipping—choose thicker mil ratings for puncture resistance and clearer film when contents must be visible

Choose seal type for your workflow

Self-seal or permanent-adhesive closures simplify packing and security; self-seal is reusable on some styles while permanent adhesive provides a tamper-evident bond

Match size to contents

Common sizes like 9x12 and 10x13 fit documents and small goods; measure items with any protective padding to ensure a proper fit and avoid overhang

Look for safety and compliance labeling

Suffocation warning printing is standard on many clear poly bags and is important for regulatory compliance and safe handling around children

Balance bulk counts versus storage

High-count packs (several hundred to 1,000) lower per-unit cost for frequent shippers but require more storage space—select quantity based on use frequency
