Winpack Self-Seal Mailer Boxes
Winpack Self-Seal Mailer Boxes
Winpack self-seal mailer boxes are designed for businesses that need fast, secure, and attractive packaging. With a simple peel-and-seal closure, these mailer boxes save time during packing and provide a tamper-resistant seal for safer shipping. Ideal for cosmetics, food, healthcare, electronics, and more, our mailers combine practicality with a polished brand presentation.
Easy to Use, Ready to Ship
Each mailer box features a strong adhesive strip—no tapes or glue required. The one-step closure speeds up packing and reduces handling errors, which is perfect for high-volume e-commerce operations and subscription services.
Customizable Design Options
Choose from multiple sizes, thicknesses, and finishes. Winpack offers full-color printing, logos, QR codes, and protective coatings to make Winpack stand out. We also provide eco-friendly kraft and recycled paper options for businesses prioritizing sustainability.
Trusted Manufacturing and Quality
Founded in 2016, Guangdong Winpack Printing Technology Development Co., Ltd. operates a 15,000-square-meter factory equipped with modern machines like the Heidelberg press and Lithrone GL-40A. Our advanced plate-making and anti-counterfeiting inkjet systems ensure consistent printing quality, clear logos, and accurate color. Every batch undergoes strict quality checks before shipping.
Secure Protection for Every Shipment
Self-seal mailer boxes are lightweight yet sturdy, offering good protection for products during transit. The tight seal reduces the risk of tampering and keeps items safe from dust and moisture. For fragile items, add protective inserts or choose a heavier board weight.
Fast Turnaround and Reliable Service
Winpack provides flexible order quantities—from small custom runs to large-scale production. Our efficient workflows and skilled team help deliver on time without compromising quality. We serve clients across cosmetics, food, healthcare, pharmaceuticals, and electronics with tailored packaging solutions.
