Worried about POF film cracking in cold storage? Guangdayuan, a Chinese protective film pioneer, delivers low-temperature resilient POF solutions for global refrigeration needs.
Technical Breakthroughs
1. Molecular Chain Plasticization
- Ethylene-vinyl acetate (EVA) copolymer intercalated into POF matrix, reducing glass transition temperature (Tg) from -10℃ to -35℃.
- Tested in Saudi Arabian ice cream factories: no brittleness at -25℃ after 1,000+ shrink cycles.
2. Cross-Linking Treatment
- Electron beam cross-linking of adhesive layers, improving tensile strength retention to 85% at -20℃ (industry average: 50%).
Refrigeration Application Benefits
| Industry | Guangdayuan POF Advantage | Regional Case Study |
|---|---|---|
| Seafood | Anti-fog inner layer prevents condensation in UAE | Dubai fish market—98% film integrity after 7 days |
| Fruits | Breathable structure for tropical produce in PH | Mango packaging—extends shelf life by 15 days |
| Medical | Sterilizable film for 印尼 vaccine vials | Passes 121℃ autoclaving without brittleness |
Performance Metrics
- Temperature Range: -30℃ to 120℃ (ideal for Middle East’s extreme temp fluctuations)
- Impact Resistance: 500g falling ball test at -18℃ with zero cracks
- Shrinkage Rate: 45% at 160℃, consistent across cold storage applications
Global Support Network
- Middle East: Free shrink tunnel calibration in Riyadh for optimal cold film performance.
- Southeast Asia: On-site training for fruit packers in Thailand to prevent low-temp cracking.
