Printed Lock Mailing Box
For brands that ship at volume, the lock bottom mailing box solves a quiet but costly problem: taping. Our self-locking base panel snaps into place in under ten seconds — no tape, no glue, no staples. That means faster packing lines, lower consumable costs, and a cleaner unboxing moment for whoever opens it on the other end. The box is built on E-flute corrugated board, a single-wall structure that keeps wall thickness at around 1.5 mm while delivering a burst strength above 200 kPa. It handles contents up to 8 kg comfortably, which cover the majority of apparel, cosmetic, and subscription kit shipments. The flute structure also absorbs impact better than solid board of equivalent weight, so you get protection without paying for dead weight on every label. Printing is where most of our customers make their biggest visual upgrade. We run full CMYK offset across the outer and inner surfaces, with optional PMS Pantone matching for brand-critical colors. Finishes include matte lamination, gloss lamination, soft-touch coating, and UV spot — applied to specific panels or the full wrap, depending on your design. The result is packaging that photograph well and holds color consistency across large production runs. From 50 units to 50,000 — we provide the same dieline support, file review, and production accountability on every order size. The minimum order quantity is 50 units, which make it accessible for product launches and seasonal campaigns. For orders above 500 units, tiered pricing applies automatically. Structural dielines are provided free in AI, PDF, and CDR formats, and our pre-press team reviews every print file before it goes to plate. All boards are sourced from FSC-certified mills, and we print with soy-based inks throughout. The finished box is 100% curbside recyclable. For buyers supplying into EU markets or working with retailers that have sustainability audit requirements, we can provide full material documentation and ISO 14001 certification on request.
