Environmental Performance	PP Hollow Board	Traditional Corrugated Paper
Recycling Rate	100% recyclable	80%-90% recyclable
Carbon Emission	Low, approximately 1.5 kg CO2e/kg	High, approximately 3.0 kg CO2e/kg
Resource Consumption	Low, mainly uses polypropylene, less energy consumption	Medium, paper manufacturing requires large amounts of water and wood
Waste in Production	Low, production waste can be reused	High, some production waste is difficult to reuse
Water Consumption	Low	High, paper pulp production requires large amounts of water
Sustainability	Excellent, polypropylene can be recycled multiple times	Limited, paper recycling consumes more energy

Performance Test Item	PP Hollow Board	Corrugated Paper
Load-Bearing Capacity	High, can bear significant pressure and weight, especially suitable for packaging applications that require support.	Low, limited by the natural strength of paper, typically used for lightweight packaging or support.
Impact Resistance	Excellent, has good shock resistance, protecting contents during transportation and stacking.	Poor, easily damaged by impact, especially in humid environments.
Temperature Change Resistance	Excellent, maintains stability over a wide temperature range (-20°C to +80°C).	Poor, easily affected by temperature changes, especially prone to deformation in high heat or humid environments.
Compression Strength	High, remains structurally stable during stacking and transportation.	Low, easily crushed or deformed, may show shape changes under load.
Moisture Resistance/Waterproof	Excellent, polypropylene material has waterproof properties, suitable for humid environments.	Poor, corrugated paper deforms and collapses easily in humid or wet conditions.
Service Life	Long, especially in dry environments, highly durable.	Shorter, particularly in humid environments where it is prone to damage.
