Buying Guide

Material and water resistance

Choose poly mailers for lightweight, tear- and water-resistant protection that helps prevent moisture damage during transit

Closure type matters

Peel-and-seal self-sealing closures speed packing and provide a secure seal without tape, useful for high-volume workflows

Pick size by accessory dimensions

Match mailer dimensions to the largest accessories you ship; oversized envelopes add cost and shifting risk while undersized ones require additional protection

Buy by pack count for value

Assess monthly shipping volume and choose bulk packs (100–1,000+) to lower per-unit cost and avoid frequent reordering

Consider tear resistance and thickness

Look for thicker, tear-resistant poly when shipping items with edges or hardware to reduce punctures and returns
