Zero-Mold Maritime Freight:
30–60 Day Cold Chain Protection
Designed for transpacific and global reefer container shipments. Eliminates "container rain" moisture damage, prevents ethylene accumulation in closed holds, and preserves produce grade from farm loading to arrival port.
Surviving the High-Risk Maritime Supply Chain
Reefer containers face power interruptions, defrost cycles, and high humidity buildup during multi-week ocean transit.
Preventing "Container Rain" & High RH Condensation
When reefer units undergo automatic defrost cycles, air temperatures fluctuate. Humidity spikes lead to condensation on inner box walls, dripping onto cartons and triggering mass fungal rot.
- Hydrophilic Anti-Fog Layer: Locks moisture into a microscopic liquid film, preventing large droplet formation.
- Carton Structural Protection: Prevents corrugated boxes from softening and collapsing under humidity.
Anti-condensation MAP liners safeguard bottom pallets from box compression damage.
Full pallet active shrouds seal entire 1.2m x 1.0m pallet stacks for rapid air-freight and sea-freight loading.
Ethylene Trapping in Sealed Container Holds
Standard container ventilation cannot fully exhaust ethylene ($C_2H_4$) produced by high-respiration produce. Accumulated gas speeds up aging across the entire load.
- In-Film Active Catalysts: Absorbs ethylene directly at the individual box/pallet level.
- Cross-Contamination Barrier: Prevents early-ripening fruits from triggering decay in adjacent pallets.
Logistics-Grade Active Packaging Solutions
Seamlessly integrates into standard packing lines, automatic pallet stretch wrappers, and RPC crates.
Active MAP Pallet Shrouds
Heavy-duty gusseted bags covering entire euro pallets. Features quick-zipper or heat-seal tops for gas flushing.
High-Strength Master Carton Liners
Puncture-resistant active liners formulated to withstand friction against rough cardboard during rough sea motion.
Smart MAP with Data Loggers
Compatible with RFID temperature/humidity sensors inside the bag for full cold-chain traceability and claims proof.
