How to Choose the Best Insulated Cardboard for Frozen Food
Not all insulation is equal—consider these factors:
1. Insulation Material
| Type | Pros | Best For |
|---|---|---|
| Foil-Bubble | Lightweight, moisture-resistant | Short-distance shipping |
| EPS Foam | High insulation, budget-friendly | Long-haul frozen shipments |
| Vacuum Panels | Ultra-thin, extreme cold retention | Premium perishables (e.g., seafood) |
2. Box Size & Ice Pack Placement
Leave minimal air space – Excess air accelerates thawing.
Place ice packs on top – Cold air sinks, improving cooling efficiency.
3. Shipping Duration & External Conditions
<24 hours: Basic foil insulation + gel packs.
48+ hours: Thicker EPS foam + dry ice.
