(3215 Copper) Pneumatic Carton Closing Staples For Packaging Wide Crown.
Global Industry Trends: Why Carton Closing Staples Remain Indispensable
The global packaging industry, valued at over USD 1,015 billion in 2023 (Smithers Research), continues to show robust demand for high-reliability carton closing staples thanks to the rise of automated packaging, e-commerce logistics, and sector compliance requirements (ISO/TC 122). Market reports highlight a CAGR of
5.7% for industrial stapling fasteners between 2024-2030, with copper-plated and anti-corrosive staples gaining traction across food, petrochemical, and metallurgical sectors.
Key Trends:
- Material innovation—copper, galvanized, and stainless finishes designed for corrosion resistance and extended lifespan.
- Automation-readiness—compatibility with pneumatic and robotic carton closing systems.
- Eco-compliance—products meeting RoHS, ISO 9001, and FDA (where food-safety relevant) standards.
- Customization—demand for tailored staple dimensions, crown widths, and wire gauges grows.

Manufacturing Process of Carton Closing Staples
→
→
→
(CNC Cut & Bend)
→
- Wire Drawing: Achieves precise gauge (0.9×2.3mm), ensuring strength and uniformity.
- Copper Plating: Utilizes electrochemical process—forms a corrosion-resistant layer universally exceeding 96h in ASTM B117 salt spray tests.
- CNC Forming: Bending and cutting are managed by 3-axis CNC, guaranteeing degree tolerance ±0.1° and sharp, consistent chisel points.
- Inspection: 100% item quality verified; production controlled by ISO9001-certified process; compliance with ANSI/BIFMA standardized packaging staple sizes.
Technical Advantage: The advanced CNC process reduces dimensional errors, while anti-fatigue testing achieves over 60,000 closing cycles per batch before distortion (3rd-party test lab, SGS).
