Key Features

Durability, ease of use, and custom branding are central to our design. Winpack's self-seal mailer boxes are available in multiple sizes and strengths, include tear strips for easy opening, and support full-color printing and spot finishes. Anti-counterfeiting inks and reinforced edges protect contents and enhance presentation.

Customization & Branding

We offer custom printing, embossing, windowing, and matte or gloss finishes so your self-seal mailer boxes match Winpack voice. High-resolution printing on our Heidelberg and Lithrone GL-40A ensures vibrant, consistent results that stand out on arrival.

Materials & Sustainability

Choose recyclable kraft, SBS, or coated options that balance protection with environmental responsibility. Our production supports eco-friendly inks and materials, allowing you to market your products with sustainable credentials while maintaining the structural integrity required for safe shipping.

Industries & Applications

Ideal for cosmetics, food, healthcare, pharmaceuticals, and electronics, these mailers protect fragile items and reduce return rates. Whether you need subscription box fulfillment, direct-to-consumer shipping, or retail-ready packaging, our self-seal mailer boxes adapt to varied logistics and branding needs.
