In food, pharmaceutical, and electronics industries, POF folded film is favored for shrink packaging—but low-temperature brittleness remains a challenge. As a 20+ year protective film expert, Guangdayuan offers specialized cold-resistant solutions.
The Low-Temperature Brittleness Problem
Standard POF films (polyolefin) become brittle below -5℃, causing cracks in cold storage (-18℃ to 4℃). Key issues:
- Molecular chain rigidity at low temps
- Insufficient impact resistance
- Adhesive layer brittleness
Guangdayuan’s R&D team, in collaboration with HIT, has developed modified POF formulations for cold environments.
Guangdayuan’s Cold-Resistant Innovations
1. Nano-Elastomer Modification
- 5% nano-silica elastomer added to POF layers, increasing elongation at break by 60% (-20℃ test).
- Tested in Dubai’s frozen food warehouses (-18℃) with zero cracking after 3-month storage.
2. Multi-Layer Co-Extrusion
- 3-layer structure:✅ Outer PE layer for abrasion resistance✅ Middle EVA-modified POF for flexibility✅ Inner anti-fog coating for clear visibility in Indonesia’s high-humidity cold rooms
Cold Storage Application Scenarios
- Food Packaging: Seafood in UAE ports—Guangdayuan’s POF folded film maintains integrity during 4℃ transport, certified by ISO 14001 for food contact safety.
- Pharmaceuticals: Vaccine packaging in Vietnam, withstanding -15℃ without film breakage.
- Electronics: Component protection in cold logistics, anti-static properties retained at 0℃.
Why Choose Guangdayuan?
- Regional Testing: Free cold chamber trials in Dubai (-25℃) and Jakarta (4℃/85% RH).
- Custom Thickness: 20-100μm films tailored for Middle Eastern meat packing vs. Southeast Asian fruit exports.
- 24/7 Support: Arabic/Indonesian technical guides for optimal cold storage use.
