Reverse Tuck Design Advantages
The reverse tuck configuration features closures that fold in opposite directions—top flaps tuck to the inside while bottom flaps tuck to the outside (or vice versa). This design offers several operational benefits over standard straight tuck cartons:
- Positive pye-lock closure: Self-locking tabs provide secure closure without requiring tape or adhesive
- Easy assembly: Cartons snap into place quickly, reducing packing time on high-volume lines
- Tamper evidence: Locked tabs make unauthorized opening more visible
- Secure product retention: Opposite-direction tucking creates tension that prevents accidental opening during handling
Applications
These compact 3x3x4 cartons serve diverse commercial packaging needs across multiple industries:
- Hardware & Fasteners: Screws, bolts, nuts, washers, small tools, and specialty fasteners
- Electronics & Components: Adapters, cables, connectors, small devices, and accessories
- Retail Products: Cosmetics, jewelry, toys, craft supplies, and gift items
- Industrial Parts: O-rings, gaskets, bearings, seals, and replacement components
- Food Service: Portion-packed dry goods, condiment packets, and sample sizes
- Office Supplies: Pens, markers, staplers, clips, and desk accessories
PPP-B-566 Federal Specification
PPP-B-566 is the federal specification for folding paperboard boxes used in commercial and government procurement. Compliance ensures the cartons meet minimum standards for:
- Material thickness and composition (.024" chipboard)
- Structural integrity and stacking strength
- Die-cutting precision and dimensional accuracy
- Manufacturing quality control standards
This specification is particularly important for businesses selling to government agencies, military installations, or organizations with federal compliance requirements.
Material & Construction
The .024" chipboard construction provides adequate protection for non-fragile items while keeping material costs economical for high-volume operations. Die-cut from continuous sheets, these cartons ship and store flat to maximize warehouse space efficiency. The kraft paperboard accepts stamps, labels, and printing, allowing for brand customization or product identification marking.
Storage and Assembly
Store flat cartons in a dry environment away from moisture, which can compromise paperboard strength. To assemble, press along scored fold lines to shape the carton, then tuck flaps according to the reverse tuck configuration. No glue or tape required—the pye-lock tabs secure automatically. Assembly takes seconds per unit, making these suitable for both automated packing lines and manual packaging stations.
