Introduction
Packaging is more than just a way to ship a product — it’s often the first physical connection a customer has with a brand. For one underwear company, creating a strong first impression was key. They needed packaging that felt modern and as playful and full of personality as the underwear inside, while keeping costs in check. They turned to us to help develop a custom poly mailing bag that could do all three.
The Challenge
The company has been growing fast and needed a shipping solution that could scale with their operations. They wanted something eye-catching, colorful, and unmistakably them. The mailer needed to stand out in a pile of packages, be instantly recognizable to repeat customers, and spark curiosity for new ones. At the same time, they couldn’t sacrifice practicality — the packaging had to be durable, efficient to ship, and affordable as they scaled up.

The Solution
Plus Packaging collaborated with the underwear brand to create a custom poly mailing bag that hit all the right notes. The mailer featured a vibrant, high-contrast design packed with color, playful shapes, and the brand’s cheeky mascot front and center. Every inch of the packaging was used to amplify the brand’s bold, irreverent voice — from the bright background patterns to the custom typography.
The material itself was a strong, flexible poly that held up well in transit, protected the product, and maintained its crisp print quality even through rough handling. It was lightweight for cost-effective shipping and easy for the warehouse team to store and pack — a perfect blend of personality with performance.

Results and Success
The final product was a win across the board. The packaging became an extension of the underwear brand — fun, bold, and instantly recognizable.
1. Brand Alignment
The bright, colorful design perfectly reflected the brand’s playful identity and helped elevate the customer unboxing experience.
2. Customer Experience
Recipients loved the packaging — it stood out in the mail and made receiving underwear feel like something worth talking about.
3. Shipping Efficiency
Despite the high-impact visuals, the poly mailers were lightweight, durable, and easy to pack — keeping logistics simple and costs in check.
4. Scalability
As the brand grew, the mailer design remained consistent and easy to reorder, helping maintain strong branding across every shipment.
The end result? A package that turned heads, sparked joy, and carried the brand’s personality all the way to the customer’s front door.
