High-Strength Corrugated Structure Customization
Based on product weight, stacking layers, and shipping distance, we design appropriate flute combinations (BC/AB/BAB) and basis weight ratios. Five-layer and seven-layer solutions meet edge crush and burst strength requirements for heavy products, with test data reports available.

Moisture-Proof & Heat-Resistant Treatment
For ocean freight high-humidity conditions and high-temperature storage areas, we offer moisture-retardant coating treatment that reduces carton moisture absorption rates and strength degradation in humid environments. Combined with moisture-proof inner bags, this forms a complete moisture protection system.

Standardized Rapid Delivery
The ERP system manages material preparation and production planning, with standard industrial cartons delivered within 7 days. Production capacity is reserved during peak seasons to ensure packaging supply never interrupts your production line.

Cost-Oriented Optimization
While meeting protection requirements, costs are controlled through flute optimization and basis weight ratio adjustments. Over-packaging is avoided — every layer of material delivers measurable protective return.
