What Are Mailer Boxes?
Mailer boxes (also called shipping boxes, tuck-top boxes, or roll-end front tuck boxes) are one-piece corrugated boxes that fold flat for storage and open to reveal a branded interior. They are the standard packaging for:
- Ecommerce orders — Branded shipping experience that replaces plain brown boxes
- Subscription boxes — Monthly deliveries for beauty, snacks, pet products, and more
- Gift packaging — Premium unboxing experience for special occasions
- Product launches — Influencer kits, press boxes, and promotional packages
- Retail packaging — In-store display boxes that double as shipping containers
Types of Mailer Boxes
1. Standard Tuck-Top Mailer
The most common style. Features a tuck-in flap that folds over the front panel. Simple, clean, and cost-effective. Available in E-flute (thin) and B-flute (thick) corrugated.
2. Tab-Lock Mailer
Includes side tabs that lock into place for a more secure closure. Better for heavier products that need extra stability during shipping.
3. Full Overlap Mailer
The lid fully overlaps the front panel, creating a seamless look when closed. Premium appearance used for luxury brands and high-end subscriptions.
4. Pizza-Style Flat Mailer
Hinged lid that opens like a pizza box. Great for flat items: clothing, prints, books, and accessories. Easy to pack and provides a dramatic reveal moment.
5. Crash Lock Bottom Mailer
Auto-locking bottom that pops into shape without tape. Speeds up packing operations for high-volume brands. The bottom stays secure without additional adhesive.
6. Telescoping Mailer
Two-piece box where the lid slides over the base. Creates a luxury unboxing experience similar to an Apple product box. Higher cost but maximum impact.
