A 1200×1000mm high-density PP food party tray has a static load capacity of 4000 kg and a dynamic load capacity of 1500 kg.
• Bagasse Fiber Food Party Trays: Limited load-bearing capacity but sufficient for single-use needs. A standard 250×200×25mm size can bear approximately 5 kg, and increasing the thickness can improve the load-bearing capacity.
• PET Food Party Trays: Load-bearing capacity is between the two. Ordinary models have a static load of 300-800 kg and a dynamic load of 100-300 kg. Through optimization, such as reinforcing ribs and double-layer structures, the load-bearing capacity can reach more than 80% of ordinary PP catering food trays.

2.2 High-Temperature Resistance

• PP PlasticFood Party Trays: Continuous use temperature 95℃, short-term 120℃, melting point 170℃, heat distortion temperature above 110℃, can be steam sterilized (121℃, 30 minutes), reusable over 500 times, good thermal stability, resistant to rapid temperature changes.
• Bagasse Fiber Food Party Trays: Resistant to 120℃ oil and 100℃ water, deformation rate less than 1% at 93℃ for 30 minutes, can handle regular hot food, but may slightly deform under drastic temperature changes.
• PET Food Party Trays: Standard type is temperature resistant from -20℃ to 60℃, not suitable for hot food; CPET is temperature resistant from -40℃ to 220℃, can be microwaved, but avoid direct transfer from refrigeration to high-temperature environments.

2.3 Water and Oil Resistance

• PP Plastic Food Party Trays: Naturally waterproof and oil-resistant, does not absorb water, resistant to solutions with pH 2-12, smooth surface, and easy to clean. One catering company reported a 30% reduction in cleaning time and 40% less detergent use after switching to these catering food trays, which are also acid and alkali-resistant.
• Bagasse Fiber Food Party Trays: Processed at 180℃ high temperature and special molding to form a dense structure, naturally oil and water resistant, no coating required, can withstand hot water and hot oil penetration for more than 30 minutes, and the oil penetration rate is less than 5% when holding oily food.
• PET Food Party Trays: Good water resistance but weak oil resistance; long-term contact with oily food may cause penetration. Through treatments such as oil-resistant coating and multi-layer composite, the oil penetration rate can be reduced to below 10%.

2.4 Other Key Performance Characteristics

• Flexibility: PP has good flexibility, not easy to break when folded, suitable for irregularly shaped packaging; PET has high hardness and strong impact resistance (1.5 times that of PP), and the box body is rigid; Bagasse is between the two, and excessive bending can easily cause cracking.
• Transparency: PET has a transparency of over 90%, suitable for display; PP is translucent or opaque, appearing clean; Bagasse is opaque, showing the natural fiber color.
• Chemical Resistance: PP has excellent chemical resistance, except for strong oxidizing acids; PET has better resistance to organic acids than other plastics; Bagasse is not resistant to strong acids and alkalis. 
• Impact Resistance: PET is the best, not easily broken; PP is good at room temperature but brittle at low temperatures; Bagasse can meet requirements under normal use, but is easily damaged by strong impacts.

III. Environmental Friendliness and Environmental Certification Analysis

3.1 Raw Material Sources

• PP Plastic Pallets: The raw material is petrochemical products, a non-renewable resource. However, recycled PP (rPP) technology utilizes waste plastics, and PP pallets containing 25-30% recycled content have performance comparable to virgin material, reducing reliance on petroleum.
• Bagasse Fiber Pallets: The raw material is sugarcane bagasse, a 100% renewable agricultural waste product. Every ton of sugarcane produces 200 kg of bagasse, and using it to make pallets can reduce 3 million tons of carbon dioxide emissions.
• PET Pallets: The raw material comes from petroleum, but it has good recyclability. Recycled PET (rPET) pallets are mostly sourced from beverage bottles. 100% rPET pallets achieve over 95% of the performance of virgin material, reducing the carbon footprint by more than 50%.

3.2 Post-Use Treatment

• PP Plastic Pallets: Can be recycled (theoretically 100%, actually 90-95%), incinerated, or landfilled. Natural degradation takes 400-1000 years, producing microplastics. Incineration produces greenhouse gases, and recycling is affected by the system and cost.
• Bagasse Fiber Pallets: Degrade in 60-90 days in industrial composting, and can also decompose in home composting. The products are water and carbon dioxide. The biodegradation rate exceeds 95% in 90 days, with a low carbon footprint and carbon sequestration effect.
• PET Pallets: Treatment methods are the same as PP, but they have high recycling value and mature technology. Chemical recycling can achieve a closed-loop cycle. For every ton of PET pallets recycled, 3 tons of carbon dioxide emissions are reduced, and 2 tons of petroleum are saved.  Without a recycling system, the degradation time is the same as PP.

3.3 Carbon Footprint

• PP plastic pallets: Full life cycle carbon emissions of 3.57 kg CO₂equivalent/kg, with the carbon footprint mainly originating from the production process.
• Bagasse fiber pallets: Due to carbon absorption during sugarcane growth, the full life cycle carbon footprint is -0.5 to -1.0 kg CO₂ equivalent/kg, achieving negative carbon emissions, but long transportation distances may offset this advantage.
• PET pallets: Virgin PET carbon emissions are 2.84 kg CO₂equivalent/kg, approximately 20% lower than PP; 100% rPET pallets reduce the carbon footprint by more than 50%, and the carbon footprint depends on the proportion and system of recycled materials.

3.4 Environmental Certifications

• PP plastic trays: Possess GRS (Global Recycled Standard), OBP (Ocean Bound Plastic), UL2809 recycled content, EU REACH, I5CC carbon certification, etc., focusing on recycling and chemical control.
• Bagasse fiber trays: Covered by EN13432 (EU compostable), ASTM D6400 (US compostable), FDA, LFGB, BPI, OK compost, etc., providing comprehensive environmental certifications.
• PET pallets: Have SCS Global certification, FDA food-grade certification, and ISO 14021 environmental declaration standards, requiring purity exceeding 95% to be compatible with recycling processes.
