Buying Guide

Choose the right size

Match mailer dimensions (examples include 14.5×19 in and 24×24 in) to your typical items to avoid wasted space or overfolding

Consider material and water resistance

Poly mailers offer lightweight, waterproof protection compared with paper envelopes and are better for textiles and non-fragile goods

Look for secure closures

Self-sealing strips simplify packing and provide consistent closure strength without extra tape or adhesives

Factor color and branding

Colored options like navy, hot pink, teal, black, or milky white can support brand identity or help sort shipments by category

Buy by pack size to match volume

Bulk pack counts (for example, 100–200 packs) reduce unit cost and are more efficient for recurring shipping needs
