Large Mailer Boxes - Durable Custom Shipping Solutions

Custom Large Mailer Boxes for Secure Shipping

Winpack’s large mailer boxes are engineered to protect oversized and heavy items during transit while presenting a polished brand experience at unboxing. Whether you ship apparel bundles, electronics, or multiple-product kits, our custom large mailer boxes provide structural integrity, tamper resistance, and clean, consistent stacking for logistics. Use custom inserts, die-cut partitions, or protective kraft fills for added security.

High Quality Materials & Advanced Printing Technology

Manufactured in our 15,000 m² facility, Winpack combines High Quality corrugated board with industry-leading presses—Heidelberg, Lithrone GL-40A—and anti-counterfeiting inkjet capabilities. Our advanced screen plate-making and high-speed finishing ensure sharp graphics and durable print that resists scuffing and moisture. Large mailer boxes can be finished with matte or gloss lamination, spot UV, or eco-friendly coatings to match Winpack aesthetic.

Tailored Solutions for Multiple Industries

We design large mailer boxes for cosmetics, food, healthcare, pharmaceuticals, electronics, and direct-to-consumer retail. Regulatory and safety needs—such as hygienic inner linings for food or anti-tamper features for pharmaceuticals—are integrated into custom specifications. Our packaging solutions align form, function, and compliance for each industry.

Seamless Design, Proofing & Fast Production

From concept sketch to approved sample, Winpack handles design, proofing, and production with precise turnaround. Our workflow includes structural design, dielines, digital proofs, and pre-production samples so your large mailer boxes ship right the first time. High-volume orders are optimized for cost and lead time without sacrificing quality.
