    Mailers

    Custom Printed Poly Mailers

    Custom printed poly mailers are lightweight shipping bags with a peel-and-seal adhesive flap. They protect soft goods in transit, cost less to ship than boxes and, printed with your brand, turn the delivery into part of the purchase.

    • Peel-and-seal adhesive flap
    • Opaque white film for privacy
    • Front and back printing

    Who ships in poly mailers

    Online stores, apparel and accessories brands, subscription boxes, retailers sending returns and replacements, and companies mailing promotional items or printed materials. They are also an easy upgrade for shops still shipping soft goods in plain stock bags.

    Film and construction

    Mailers are made from white polyethylene film, opaque enough that the contents stay private. The film is tough and flexible, so it stands up to tears and punctures on the way to your customer.

    Branding and print

    Print your logo, a pattern, a social handle or a thank-you message on the front and back. With up to 8 print colors, bright brand graphics stand out on a doorstep and in unboxing photos, and a consistent branded mailer makes every order look polished.

    Closures and sizes

    A peel-and-seal adhesive strip closes the mailer quickly and securely with no tape. Sizes are made to fit your products, from small accessories to folded garments.

    Why Metro

    Your mailers are printed and made in our Brooklyn plant, so you get custom branding from a domestic manufacturer, typically 3–4 weeks from approved artwork.

    Poly Mailer Bags FAQ

    Are poly mailers water-resistant?

    Yes. Polyethylene film resists water and moisture, which helps protect the contents in rain or snow.

    Can I print on both sides?

    Yes. The front and back can both carry your artwork.

    Can people see through the mailer?

    No. We use opaque film so the contents cannot be seen through the bag.
