27% of cosmetic quality issues stem from improper packaging choices (Euromonitor, 2024). This guide reveals the hidden science behind PP, PET, and PETG through lab-tested data and industry benchmarks.
1.Three-Dimensional Material Analysis
According to IPAC’s 2024 test data, key differences are:
- Chemical Resistance: PP ★★★★★ | PET ★★★☆☆ | PETG ★★★★☆
- Recyclability: PP ★★★★☆ | PET ★★★☆☆ | PETG ★★☆☆☆
- Cost Efficiency: PP ★★★★☆ | PET ★★★☆☆ | PETG ★★☆☆☆
