Revolutionize Your eCommerce Shipping with Custom Printed Poly Mailers
For modern online retailers, the shipping bag is the first physical touchpoint with a customer. When we manufacture custom poly mailers at our centers in Issaquah and Los Angeles, we use co-extruded polyethylene. This multi-layer technology makes the bags opaque for privacy and significantly stronger than standard retail plastic bags. If you are shipping apparel, soft goods, or boxed items that need moisture protection, our mailers offer a secure, lightweight alternative that lowers your postage costs while boosting brand recognition.
Engineering Maximum Security for Every Package
The core benefit of our poly mailers is their tear and puncture resistance. Unlike paper-based alternatives, these bags are designed to withstand the friction of automated sorting belts. Each bag features a permanent, tamper-evident adhesive strip; once sealed, it cannot be opened without showing visible damage. For brands looking for a more organic feel for non-shipping needs, our eco-friendly kraft bags are an excellent choice, but for long-haul shipping, the durability of poly is unmatched.
Professional Branding at Every Touchpoint
Generic white or grey mailers disappear in a pile of mail. Our high-definition flexographic printing allows you to cover the entire surface with your brand colors, logos, and social media handles. For smaller items or delicate products that require a unique presentation before going into a mailer, our custom pillow pouches can serve as the primary inner packaging. By coordinating your designs across all these elements, you create a cohesive and professional unboxing experience.

Frequently Asked Questions About Custom Poly Mailers
Get the facts on sizing, waterproof features, and design options for your custom shipping bags.
View All FAQs →Are poly mailers waterproof?
Yes, our poly mailers are made from moisture-resistant polyethylene. The self-sealing flap creates a secure barrier that protects your contents from rain, snow, and spills during the delivery process.
Can I print on the back of the mailing bag?
Absolutely. We offer full-bleed printing on both the front and back of the mailer, as well as on the closure flap. This gives you 360 degrees of branding space for your marketing messages.
What is co-extruded plastic?
Co-extrusion is a process where multiple layers of plastic are bonded together. This creates a bag that can be one color on the outside (like your brand's blue) and another on the inside (usually grey or black) to ensure the contents are not visible.
Do you offer eco-friendly shipping options?
Yes, we provide poly mailers made from 100% recycled content and options that are fully recyclable at plastic drop-off locations, helping your brand meet its sustainability goals.
Will these bags work with standard shipping labels?
Yes, our mailers are designed with a surface that accepts standard thermal shipping labels and permanent markers without smudging, ensuring your addresses remain legible for carriers.
