Project Background

• Environmental pressure: Generating approximately 95 tons of non-biodegradable plastic packaging waste annually, which led to a 12% loss of consumers due to the "non-eco-friendly" brand image.
• Misaligned brand positioning: The low-cost texture of PET jars failed to match the brand’s "organic, premium" positioning.
• Cost volatility: PET material procurement costs fluctuated by up to 18% annually due to crude oil prices, causing budget instability.

Customized Solution

1. Eco-Conscious Material Selection
   • Used food-grade tinplate compliant with EU food contact standards, printed with water-based inks free of heavy metal residues.
   • Clearly labeled "100% Recyclable Tinplate" with recycling instructions to raise consumer environmental awareness.
   
   
2. Freshness-Locking Structure Upgrade
   • Integrated double-layer food-grade silicone gaskets, extending the nut shelf life from 6 months (PET cans) to 9 months.
   • Reduced food waste from spoilage, indirectly lowering carbon emissions.
   
   
3. Lightweight Design Optimization
   • Optimized can body curvature and wall thickness to reduce single-can weight from 165g to 142g while maintaining structural strength.
   • Cut raw material usage by 14% and reduced per-can carbon footprint by approximately 0.32kg CO₂e.
   
   

Project Results

• Environmental Impact: After implementation, the client eliminated ~95 tons of plastic waste annually, equivalent to reducing 380 tons of CO₂ emissions (equal to the annual carbon sequestration of 21,000 trees).
• Market Response: Post-upgrade, brand repurchase rate increased by 18%, with 23% of new customers citing "eco-friendly packaging" as their primary reason for choosing the brand.
• Brand Value: The packaging solution won the industry "Green Packaging Innovation Award," helping the client successfully enter 3 high-end organic supermarkets.
• Cost Stability: Tinplate material prices fluctuate by only 5% annually, enabling long-term cost control for the client’s packaging budget.
