About Custom Poly Mailers
Custom poly mailers are the go-to shipping solution for e-commerce brands shipping lightweight, non-fragile products like clothing, accessories, books, and soft goods. They cost 50-70% less than corrugated boxes while reducing dimensional weight charges — saving you money on every shipment.
Cubit manufactures poly mailers from 2.5mil to 4mil co-extruded polyethylene film with a permanent adhesive strip closure. Available in sizes from 6x9" to 19x24", with custom sizes available. Full-color exterior printing transforms every package into a branded touchpoint.
Our lineup includes standard poly mailers, bubble-lined poly mailers (for extra protection), biodegradable/compostable options (made from cornstarch PLA), and recycled-content mailers (made from 100% post-consumer recycled plastic).
Every mailer features a double peel-and-seal strip for easy returns, water-resistant construction, and tamper-evident closure. Custom options include interior printing, thank-you messages, QR codes, and social media handles. MOQ starts at 500 units with 10-14 day production.
