Commercial Large Cold Storage Box "Z Pack"

Introducing the "Z Pack," a large commercial cooler box available in stock that addresses the issue of small sizes in foam and resin molded cooler boxes.
We offer five sizes: 75, 90, 150, 240, and 300 liters. It excels when you need to transport large quantities of refrigerated or frozen goods at once.
Made with high-quality domestically produced aluminum-coated fabric, it reflects direct sunlight and reduces radiant heat. The core material is a 30mm thick insulation board used in construction materials, providing high insulation performance and durability.
As reference data, we present the temperature test results assuming the delivery and storage of bottled beverages in an environment with an outside temperature of 40°C. By using cold packs in conjunction with the cooler box, it is possible to maintain a refrigerated state below 10°C for 12 hours.
Test conditions:
Cooler box used: Z Pack 75L
Cold pack used: 0°C grade cold pack, 2kg
Contents: 10 bottles of 500ml bottled water
