Solution / 0–10°C Insulated Box
9L-EPS 0–10°C Insulated Box Configuration Plan
A passive chilled-packaging configuration using an EPS insulated box and 0°C phase-change ice packs. This plan is intended for temperature-sensitive goods that need a 0–10°C internal range during short-to-medium duration cold chain transport under warm ambient conditions.
Application Scope
A 0–10°C EPS Packout for Chilled Cold Chain Delivery
This configuration is suitable for chilled product shipments where insulation, refrigerant placement, and internal temperature distribution must be reviewed together. Typical use cases include chilled food, fresh produce, seafood, diagnostics, samples, and other goods that can be handled within a 0–10°C range.
Chilled Temperature Protection
Designed for projects that need chilled protection without using an active refrigeration system. Final suitability depends on the product, route, and handling conditions.
Lightweight Insulated Packaging
EPS insulation helps reduce heat transfer during transport while keeping the package lightweight for express delivery, sample shipment, and short-to-medium distribution.
Phase-Change Ice Pack Layout
The configuration uses 0°C phase-change ice packs. Pack quantity, position, and preconditioning should be matched with payload volume and route duration.
Project Requirement
Requirement and Test Basis
The original requirement is to maintain chilled internal conditions for more than 36 hours under a warm ambient profile. The recorded test was performed in a 27.7–33.3°C environment, with an average ambient temperature of 31.1°C.
Target Requirement
Maintain an internal chilled condition for more than 36 hours in an approximately 32°C ambient environment. For publication clarity, the performance statement should be aligned with the measured 0–10°C test range.
Measured Result
In the recorded test, the limiting measurement point maintained 0–10°C for 39 hours, exceeding the 36-hour chilled-packaging requirement for this specific packout.

Packout Workflow
How This 0–10°C Packout Should Be Reviewed
Before using this configuration commercially, the packout should be checked against the actual payload, route profile, shipment duration, and carton handling conditions.
Confirm the Payload
Define product type, payload volume, payload mass, and whether the product is sensitive to freezing, condensation, or temperature fluctuation.
Review the Box Fit
Check the internal dimensions, payload space, ice pack position, air gap, and whether the listed volume matches the final packaging drawing.
Prepare the Ice Packs
Use the correct preconditioning method for 0°C phase-change ice packs and keep the packout layout consistent during test and shipment.
Validate the Route
Compare the test environment with the actual route, season, handoff time, and expected ambient temperature profile.

9L-EPS 0–10°C Configuration FAQ
These questions help buyers and logistics teams understand how to evaluate this EPS insulated box packout.
What does the 0–10°C range mean for this configuration?
It means the recorded test evaluated how long the internal temperature stayed between 0°C and 10°C. This is different from saying the package stayed exactly at 0°C for the full duration.
Why is the top position used for the final 39-hour conclusion?
In the recorded test, the top position had the shortest 0–10°C duration. Using the limiting position gives a more conservative conclusion for the full package.
Can this configuration be used for every chilled shipment?
No. Actual performance depends on payload mass, product sensitivity, ice pack preconditioning, ambient temperature, carton handling, route duration, and the final packout layout.
What information should be provided before requesting a custom version?
Please provide the product type, payload volume, target temperature range, route duration, expected ambient temperature, box size preference, and whether the package is for single-use or repeatable use.
