Thin-walled injection-molded PP materials crack the "dual paradox of strength and carbon reduction" in the packaging industry

1. Technological Subversion: A Wall Thickness of 0.12 Millimeters Can Withstand a Dynamic Impact of 20 kg

Traditional thin-walled injection-molded PP materials will experience stress cracking when the wall thickness is less than 0.3 millimeters. Through the technology of "nano-crystal nucleus induction + melt elasticity control", EcoThin-PP 900 implants plant cellulose nanowhiskers during the polymerization stage, increasing the crystallinity of the material to 65% and the impact strength to 58 kJ/m². According to the detection by SGS, the lunch box with a thickness of 0.12 millimeters shows no deformation after 300 cold and hot cycles between -18°C and 121°C. In the vertical load test, it can withstand a dynamic load of 20 kg, and its performance is comparable to that of PS materials, but the thickness is reduced by 40%.

2. Low-carbon Revolution: Bio-based Content Reaches 51%

This material uses bio-based propylene extracted from the liquefaction of straw as the core raw material, and its carbon footprint is 72% lower than that of petroleum-based PP, reducing CO₂ emissions by 2.3 tons per ton of product. The独创的 "closed-loop recycling system" can crush and re-granulate the used packaging three times and still maintain 92% of its original performance. The enzymatic hydrolysis process jointly developed with Dow Chemical can even achieve composting degradation within 6 months.

3. Scene Breakthrough: From Fresh Food Cold Chain to 3C Protection

- **Food Packaging**: Mengniu Group has trialed the use of this material to produce yogurt cups with a thickness of 0.15 millimeters. The tolerance to sterilization temperature has been increased from 95°C to 135°C, and the energy consumption of the production line has decreased by 25%. - **Daily Chemicals Field**: The packaging thickness of the laundry beads of Blue Moon has been reduced to 0.18 millimeters, the puncture strength has increased by three times, and the transportation damage rate has dropped to zero. - **Electronic Products**: The Huawei Pura 80 mobile phone tray adopts a thin-walled design with a thickness of 0.2 millimeters. The electromagnetic shielding effectiveness reaches 65dB, and the weight is reduced by 50%.
