As a factory that has been producing insulated boxes and cold chain solutions for many years, we often receive the same question from distributors and brand owners:
“How do I keep my ice cream frozen for a full day of delivery?”
Ice cream is one of the most temperature-sensitive products in the frozen category. Once the temperature fluctuates, the texture changes immediately. Because of this, many customers come to us looking for a more stable and durable cooler box—not just a standard foam box.
Below are some key points from our recent projects and what we usually recommend for ice cream transportation.
Delivery schedules are unpredictable. A truck may leave the warehouse early in the morning and return only in the evening. To avoid melting, you need a cooler box that can hold temperature for at least half a day.
Our ice cream cooler boxes can maintain up to 12 hours of cold retention when used with properly frozen ice packs. We run real tests for every batch, because stability is more important than the theoretical numbers.
For small convenience store distribution, regional delivery, or mini-store resupply, this duration fits perfectly.
Different brands of ice cream require different temperature levels. Some products soften easily, while others need a lower temperature to keep their shape and mouthfeel.
To match these needs, our cooler boxes support three common temperature points:
−15°C – suitable for short-distance delivery or softer ice cream
−18°C – the most widely used setting in the ice cream industry
−21°C – ideal for premium products or delivery in hot regions
With the right ice pack combination, the temperature stays stable throughout the entire route—no sudden warming, no inconsistent cooling.
Cold retention is important, but durability is just as critical. Ice cream boxes are carried, stacked, loaded, and unloaded every day. A weak box will quickly crack or deform.
As a manufacturer, we use:
Food-grade HDPE for the outer shell → strong impact resistance, no deformation
Integrated PU foaming inside → high insulation density, long-lasting structure
Some of our customers are still using their boxes after 3–5 years of daily operations. The long service life helps reduce replacement costs and keeps the delivery system running smoothly.
Ice cream cannot tolerate temperature swings. Once it melts and refreezes, the texture is permanently damaged. To avoid loss and customer complaints, a good cooler box needs to offer:
Stable temperature throughout the journey
Strong and durable construction
Easy handling and transport
Sufficient cold retention for a full working day
This is why many distributors upgrade from regular foam boxes to HDPE + PU cooler boxes—they simply perform better in real-world logistics.
If your business relies on frozen product delivery, choosing the right cooler box will directly affect your product quality and customer satisfaction.
As a factory specializing in cold chain products, we provide various sizes, custom colors, and logo options. We also offer guidance on matching ice packs to achieve the temperature level you need.
