### The Workhorse of Global Logistics: FEFCO 0201 Regular Slotted Cartons
Custom **RSC Boxes** (Regular Slotted Cartons, standardized as **FEFCO 0201**) represent the most universally utilized and cost-effective corrugated shipping containers in global supply chains. Engineered from certified single-wall and double-wall corrugated board ranging from **32 ECT to 48 ECT (and up to 275# Mullen burst)**, the RSC features flaps of equal length from the score to the cut edge (equal to half the container's width).
> "Regular Slotted Cartons generate virtually zero paperboard manufacturing scrap, making them up to 25% more cost-effective per cubic foot than die-cut corrugated mailers."
When folded closed, the two outer length flaps meet flush at the exact center line without overlapping, creating an unbroken planar surface ready for automated case-taping, reinforced water-activated gummed paper tape, or hot-melt adhesive.
> "Constructed with calibrated 44 ECT and 48 ECT double-wall fluting, our custom RSC cartons withstand over 900 lbs of top-load compression stacking strength on standard 40x48 inch warehouse pallets."

### Key Structural & Operational Advantages
- **Maximum Raw Material Efficiency:** Because all four flaps are identical in length, RSC blanks nest with 100% sheet utilization on corrugator slotter machines, eliminating tooling dies and minimizing board cost.
- **Center-Seam Flush Closure:** The outer flaps meet perfectly at the center, creating a tight seam that seals cleanly with a single strip of tape across the top and bottom.
- **Pallet-Modular Stacking Rigidity:** Engineered with vertical fluting orientation, RSC boxes deliver superior vertical column compression strength, allowing safe stacking up to 5 tiers high in warehouse racking.
- **Certified Box Maker Certificate (BMC):** Every manufactured carton includes an official round Box Maker Certificate stamp guaranteeing ECT rating, maximum bursting test, and carrier compliance with UPS, FedEx, and freight rail standards.
- **High-Speed Automated Packing:** Shipped flat in bundled or palletized stacks. Warehouses can erect, fill, and tape cartons manually in under 6 seconds or integrate seamlessly with automated case-erecting and case-sealing machinery at speeds exceeding 40 boxes per minute.
