Buying Guide

Choose the right size

Match mailer dimensions (14.5x19 in or 24x24 in) to typical garment sizes to minimize wasted space and prevent overfolding

Prefer waterproof poly for apparel

Poly mailers offer moisture resistance and tear resistance compared with paper options, helping protect clothing during transport

Check closure type

Self-sealing adhesive strips speed packing and reduce the need for additional tape or heat-sealing equipment

Balance pack count vs. cost

Higher-count packs lower per-mailer cost for high-volume shippers, while smaller packs can suit low-volume operations or color testing

Consider color and branding

Colored or opaque mailers (navy, black, teal, milky-white) hide contents and can support brand presentation or privacy needs
