Vacuum Cooling Stability: Preventing Box Implosion with Rigid PP Corrugated Design

Vacuum cooling is the fastest way to cool leafy greens and herbs. However, the extreme pressure changes within a vacuum chamber can cause weak cardboard boxes to implode or deform. MingPlastics’ High-Rigidity PP Corrugated Boxes are designed to withstand the physical stresses of vacuum cooling without losing their shape.

Engineering for Pressure and Precision

• High Structural Integrity: The twin-wall fluted core provides a high strength-to-weight ratio, ensuring the box walls don’t buckle under rapid atmospheric changes.
• Standardized Geometries for Automation: Our boxes maintain their dimensions perfectly, ensuring they fit seamlessly into vacuum chambers and automated palletizers.
• Efficient Moisture Retention: While allowing for gas exchange, the non-porous PP material helps retain internal humidity, preventing the “drying out” effect of the vacuum process.

Sustainable ROI

Switching from disposable to MingPlastics reusable PP boxes for your vacuum cooling process provides a measurable return on investment in just months.
