Shipping in a plain brown bag tells customers nothing. Shipping in a custom poly mailer with your logo on the outside creates a branded unboxing moment the second the package arrives. iSellPackaging produces custom poly mailers engineered for eCommerce speed, warehouse durability, and customer appeal, with minimums low enough for growing brands and pricing tiers that scale with your volume.
Every custom poly mailer we manufacture is lightweight, water-resistant, tear-resistant, and self-sealing. Choose from solid colors, gradients, full-bleed prints, recycled and compostable films, and sizes from jewelry-pouch small to jacket-shipping large.

Why Brands Switch to Custom Printed Poly Mailers
Corrugated boxes are expensive to source, expensive to ship, and rarely earn a second look. A polymailer weighs a fraction as much, takes up almost no storage space, and puts your brand directly into the customer’s hands. For apparel, accessories, cosmetics, books, soft goods, and any non-fragile product, switching to custom shipping bags typically reduces dimensional weight charges and material costs at the same time.
- Lightweight construction that lowers postage and dimensional weight fees
- Self-sealing adhesive strip with a tamper evident closure that protects products in transit
- Water-resistant coextruded film that shrugs off rain, humidity, and conveyor spills
- Tear-resistant polyethylene rated for high-speed fulfillment operations
- Compact flat-pack storage that frees up warehouse space compared with boxes
Applications: Who Ships with Custom Poly Bags for Shipping
Custom mailer bags fit a wide range of industries, but they dominate anywhere non-fragile goods move in volume:
- Apparel and fashion brands shipping shirts, dresses, hats, and accessories
- eCommerce sellers on Shopify, Amazon, Etsy, and direct-to-consumer platforms
- Subscription box companies using printed mailers as outer shipping packaging
- Cosmetics, health, and wellness brands shipping soft-pack products and samples
- Print-on-demand operations shipping posters, books, and flat printed goods
- 3PL fulfillment centers standardizing on a few mailer sizes to speed packing
