- Extends fruit export shelf-life by over 2.5 times
- Drastically cuts moisture accumulation & decay rates
Nano Meat & Poultry Packaging
Multi-functional active barrier packaging engineered for fresh meat, poultry, and seafood. Integrates drip absorption, drip-loss prevention, and bacterial suppression.
- Inhibits bacterial growth & maintains natural meat bloom
- High-barrier EVOH/PA oxygen & water vapor isolation
- FDA & SGS food-grade certified material
Patented Low-Temp PE Shrink Film & Bags
Proprietary processing technique providing up to 80% shrinkage rate at reduced tunnel temperatures. Available in single, transverse, longitudinal, or dual-axis orientation.
- Up to 80% shrinkage rate at lower energy consumption
- Tailored mono-directional & bi-directional orientation
- Exceptional puncture strength & seal durability
POF (Polyolefin) Shrink Films & Bags
Eco-friendly, 5-layer co-extruded POF shrink packaging featuring ultra-high clarity, high tensile strength, and seamless performance on high-speed automated machinery.
- 100% recyclable, non-toxic food-grade polyolefin
- Crystal-clear optical gloss & tight contour fit
- Designed for high-speed Flow-Wrap & L-Sealer lines
Supply Chain Loss Rate
Drastically cuts fresh produce spoilage and waste during long-distance cold-chain transport.
Shelf Life Extension
Physical ethylene decomposition & anti-fog action prolong freshness without chemical additives.
Countries & Regions
Trusted by leading fruit exporters, agricultural hubs, and retail chains worldwide.
How Physical Nano Preservation
Outperforms Traditional Packaging
Unlike chemical preservers that leave residues, Dehui’s patented nano-matrix directly modifies the micro-environment around fresh produce—ensuring food safety and maximum shelf-life.
Zero Chemical Additives.
Pure Physical Action.
-
Physical Antibacterial Action: Destroys bacterial cell membranes upon contact without chemical migration.
-
Active Ethylene Catalysis: Decomposes aging-catalyst ethylene gas continuously inside the package.
-
Micro-Bionic Anti-Fog: Eliminates condensation droplets, preventing mold growth and preserving clarity.
≥96% Antibacterial Rate
Inhibits major decay pathogens (E. coli, Staph) to prevent premature rot in berry & fruit shipments.
Ethylene Decomposition
Breaks down ethylene gases into harmless water & CO2, slowing respiration and aging rates.
High Transparency Anti-Fog
Maintains crystal-clear display in supermarket cold display cases, boosting retail shelf appeal.
Eco-Friendly & Recyclable
Fully compliant with global green packaging regulations, FDA food contact, and EU standards.
Smart Packaging Engineered for
Every High-Value Produce Category
Customized permeability, anti-fog performance, and physical active matrices tailored to the specific respiration rates of different fruits and vegetables.
