This case focuses on a leading domestic IVD (in vitro diagnostics) manufacturer.
The company produces more than 20 types of clinical diagnostic reagents.
Its product line covers biochemical, immunological, and coagulation detection reagents.
It supplies stable reagent products to over 50 cooperative domestic hospitals.
All liquid diagnostic reagents require strict cold chain control at 2–8°C.
The factory needs to transport 10L reagent batches to hospital laboratories regularly.
Constant temperature stability and container cleanliness are core transportation requirements.
Existing Drawbacks of Traditional Containers
The manufacturer previously used traditional rigid plastic drums for reagent delivery.
These rigid containers have fixed volume and heavy weight, increasing shipping costs.
High transportation volume caused extra logistics fees during long-distance distribution.
Rigid drums were repeatedly recycled and manually cleaned after each delivery.
Residual cleaning agents easily remained on the inner plastic wall.
Residual chemicals raised hidden contamination risks for sensitive diagnostic reagents.
Unstable cleanliness often affected reagent purity and detection accuracy.
Customized Liquid Container Solution
To solve high freight costs and contamination risks, the manufacturer adopted our liquid transport cubic container.
This 10L container is made of high-purity food-grade LDPE raw materials.
It complies with FDA and EU 10/2011 food contact material standards.
As a disposable cubical liquid transport container, it abandons repeated usage.
It eliminates chemical residue and cross-contamination caused by recycled drums.
The product has passed UN 3373 biological safety packaging certification.
It meets international transportation standards for biological diagnostic liquids.
Structural & Functional Advantages
The container is designed with a shock-absorbent outer protective layer.
The inner layer adopts an integrated leak-proof seal structure.
It can withstand continuous vibration during 48-hour long-distance cold chain transportation.
The cubical shape maximizes the loading rate of cold chain transport vehicles.
After use, the collapsible body can be compressed flat for easy disposal.
The collapsible design reduces empty shipping volume by 75%.
Compared with rigid drums, it successfully cuts comprehensive freight costs by 40%.
9-Month Distribution Trial Results
The manufacturer launched a 9-month continuous distribution trial.
The trial covered more than 500 cold chain shipment records.
Throughout the trial period, zero contamination and zero leakage occurred.
All delivered diagnostic reagents maintained stable biological potency.
The reagent concentration variance was strictly controlled within ±2%.
No fluctuation affected clinical diagnostic accuracy in cooperative hospitals.
Stable Data & Long-term Promotion
Hospital laboratories gave highly positive feedback on the new containers.
The user satisfaction rate reached 100% regarding usability and reagent stability.
This collapsible cubic plastic liquid container has been added to official distribution SOPs.
It has become the exclusive packaging for all IVD diagnostic reagent shipments.
The new packaging system standardized the factory’s cold chain distribution process.
