Buying Guide

Choose the right size

Match mailer dimensions to your typical contents—options here range from mid-size 14.5x19 in to large 24x24 in to reduce empty space and postage costs

Prefer poly over paper for moisture resistance

Poly mailers provide water and tear resistance for non-breakable goods and are available in multiple colors and sizes in this selection

Consider pack count for unit cost

Higher-count packs (100–200) lower per-mailer cost; weigh storage space against frequency of use when choosing pack size

Look for self-sealing closures

Self-sealing strips speed packing and avoid the need for separate tape, improving throughput for bulk shipments

Use color to organize orders

Colored poly mailers (navy, black, teal) help visually sort different product lines or destinations and can streamline fulfillment workflows
