RSC Boxes vs. RETT Corrugated Mailers
When choosing corrugated packaging, box style directly impacts cost, strength, speed of packing, and customer experience. Two of the most common options are the Regular Slotted Container (RSC) and the Roll-End Tuck-Top (RETT) mailer. While both protect products well, their design differences make each suited for very different needs.
Regular Slotted Container (RSC)
Design & Features
- Flaps of equal length meet in the center.
- Requires tape, glue, or staples for closure.
- Minimal board waste, highly efficient to manufacture.
Advantages
- Strong and Stackable: Excellent compression strength for palletized loads.
- Cost-Efficient: Standardized design lowers production cost.
- Versatile: Common in nearly every industry.
Limitations
- Slower Assembly: Tape or glue required for every box.
- Basic Presentation: Not designed for branded unboxing experiences.
Roll-End Tuck-Top (RETT) Mailer
Design & Features
- Single-piece die-cut design.
- Built-in dust flaps protect contents from debris.
- Cherry locks (small locking tabs) keep the lid secure without tape.
Advantages
- Fast Assembly: Self-locking design saves time and eliminates tape.
- Premium Look: Ideal for branded unboxing and e-commerce.
- Better Closure: Dust flaps improve integrity; cherry locks prevent accidental opening.
Limitations
- Higher Cost: Requires custom tooling and more board.
- Lower Stacking Strength: Not as durable for bulk palletized shipping.
- Less Flexible for Large Sizes: Best suited to small-to-medium e-commerce parcels.

Buyer Takeaways
- Choose an RSC if you need maximum stacking strength and shipping efficiency. Perfect for palletized loads, warehouses, and industrial distribution.
- Choose a RETT mailer if your focus is branding, presentation, and fast assembly. Ideal for e-commerce, D2C shipments, and subscription boxes.
- Dust flaps and cherry locks make RETT mailers especially well-suited to online retail, where presentation and secure delivery both matter.
