I. Key Product Highlights
-
Scientific Multi-Layer Protection: Available in both 3-layer (single-wall) and 5-layer (double-wall) composite structures. The 3-layer options offer lightweight flexibility to minimize postage costs, while the 5-layer options provide heavy-duty reinforcement for long-haul transit and high-value fragile goods.
-
Premium Corrugated Flute Matrix (B / C / BC / EB Flutes): Engineered with precision-formed flutes that act as an internal shock-absorption system, significantly lowering product damage rates during turbulent transit and accidental drops.
-
Precise Hardness Grading: Hardness ratings span from 1 to 5 Stars (from standard economy to super heavy-duty). Our top-tier “5-Layer Super Heavy-Duty” cartons provide military-grade compression resistance, preventing box collapsing even under multi-layer stacking.
-
Industry-Standard Sizing & Clean Die-Cuts: Covers 12 distinct industry-standard sizes, from the spacious No. 1 box (530mm) down to the micro-sized No. 12 box (130mm). Precision die-cut edges ensure quick assembly, perfectly square corners, and tight tape sealing.
