Hydro-cooling Resilience: Why Only PP Corrugated Can Handle Deep-Water Immersion

Hydro-cooling is a vital post-harvest process for removing field heat from crops like broccoli and asparagus. This involves immersing boxes in freezing water or high-pressure sprays. Traditional cardboard, even with wax coating, eventually disintegrates, leading to massive product loss. MingPlastics’ Hydro-cooling Grade PP Corrugated Boxes are engineered for absolute water immunity.

Surviving the Flood for Freshness

• 100% Waterproof Structure: Polypropylene is naturally hydrophobic. Our boxes maintain 100% of their structural rigidity while submerged, ensuring your produce stays protected.
• Fast-Drain Geometry: We customize the base of the boxes with precision-cut drainage holes to ensure no stagnant water remains, preventing bacterial growth.
• Zero Fiber Shedding: Unlike paper boxes that shed cellulose fibers into the hydro-cooling water, our PP boards are 100% clean, keeping your cooling system filters clear.

Certified Food Safety

Our boxes are FDA and FCM certified, ensuring that no chemicals migrate from the packaging into the cooling water or your premium produce.
