Engineering the Future of
Fresh Produce Preservation
Dehui Packaging is a premier manufacturer of Active Modified Atmosphere Packaging (MAP) and polymer science solutions. We empower global growers, exporters, and retailers to eliminate food waste across long-distance supply chains.
Dust-Free Cleanroom & Precision Co-Extrusion
Food contact safety is non-negotiable. Our production lines operate under strict ISO Class 8 (100,000-level) dust-free cleanroom environments, preventing microscopic particulate contamination during film blowing and bag converting.
- 9-Layer High-Barrier Co-Extrusion Lines: Precision resin blending with active catalytic masterbatches.
- Automated Micro-Perforation: Online laser density calibration matching individual crop respiration rates ($O_2/CO_2$).
- Closed-Loop Cleanliness Protocol: Full traceability from virgin raw resin to sealed master cartons.
