Product Description
Topsun EPP foam cooler box is a lightweight, durable and reusable insulated transport container for food delivery, cold chain logistics, temperature-sensitive shipments and protective transport applications.
Made from Expanded Polypropylene foam, the molded box combines thermal insulation with impact absorption, low weight and good dimensional recovery. These properties make EPP suitable for logistics systems in which containers are handled repeatedly and need to protect both the payload and the temperature-control packout.
EPP cooler boxes can be evaluated for food distribution, meal delivery, fresh-product logistics, pharmaceutical transport, laboratory samples, reusable supply-chain packaging and protective industrial shipments. Box dimensions, internal structure, lid design, density and other molded features can be developed according to project requirements.
Thermal insulation: EPP foam helps reduce heat transfer between the payload and the surrounding environment.
Impact protection: molded EPP can absorb shocks during loading, handling and transportation.
Lightweight construction: low box weight makes repeated manual handling and route distribution easier.
Reusable design: EPP has good resilience and is suitable for transport systems involving repeated logistics cycles.
Low water absorption: EPP is suitable for environments where containers may encounter condensation, ice packs or moisture during transport.
Protective structure: the rigid molded box helps protect cartons, food packs, bottles and other payloads against direct mechanical impact.
Custom molded design: size, shape and internal structure can be evaluated according to payload and logistics requirements.
Custom inserts and dividers: internal components can be evaluated to position products, coolant packs or accessories.
Recyclable polypropylene material: EPP is based on polypropylene and can be incorporated into suitable material recycling systems.

The following image shows the existing EPP cooler box specification information. For project selection, confirm the required external dimensions, internal dimensions, payload volume, wall thickness, density, coolant arrangement and transport conditions.
Cold chain transportation requires more than an insulated box alone. The complete transport system normally includes the EPP container, payload, coolant packs, internal arrangement, route duration and defined environmental conditions.
EPP foam cooler boxes provide an insulated outer structure that can be used with an appropriate coolant layout to help control temperature fluctuation during transport.
For cold chain projects, customers should provide the required temperature range, transport duration, outside temperature, payload quantity and coolant plan so the box configuration can be evaluated for the intended route.
EPP cooler boxes can be used in suitable food distribution systems for meal boxes, fresh products, bakery products, beverages, dairy products and other goods requiring insulated transport.
The lightweight box construction supports repeated loading and unloading, while the molded walls protect the contents against impacts that can occur during delivery operations.
Internal dividers, product positioning and coolant placement should be designed according to package dimensions and the required delivery workflow.
EPP insulated containers can also be evaluated as part of transport systems for pharmaceuticals, diagnostic materials, laboratory samples and other temperature-sensitive payloads.
For these applications, the required temperature range and holding time should be validated using the intended payload, coolant arrangement, temperature monitor, ambient conditions and transport route.
Customers with regulated transport requirements should provide the applicable validation protocol, operating procedure or packaging qualification requirement when discussing the project.
Reusable containers can reduce the need to replace packaging after every delivery cycle and are particularly useful for closed-loop distribution networks.
EPP cooler boxes can be evaluated for warehouse-to-store distribution, central kitchen delivery, branch replenishment, last-mile delivery, inter-site transportation and other logistics systems in which containers return for repeated use.
Box condition should be inspected between cycles, including the lid fit, corners, internal surfaces and any damaged areas that may affect protection or insulation performance.
EPP boxes are not limited to temperature-controlled logistics. Their impact-absorbing structure can also protect electronics, mechanical parts, instruments and other products during transport.
Custom internal cavities, inserts or dividers can help control product movement and separate sensitive components from direct contact with the outer box walls.
| Application | Typical Requirement |
| Cold Chain Logistics | Insulated transport with a defined payload and coolant configuration. |
| Food Delivery | Reusable insulated transport for suitable food and meal packages. |
| Fresh Food Distribution | Temperature-controlled transport with suitable coolant planning. |
| Pharmaceutical Logistics | Validated insulated packaging systems for temperature-sensitive shipments. |
| Laboratory Samples | Protective temperature-controlled transport under an appropriate validated packout. |
| Last-Mile Delivery | Lightweight reusable box for repeated delivery routes. |
| Returnable Logistics | Reusable container for closed-loop supply chains and inter-site distribution. |
| Industrial Protective Packaging | Impact protection for electronics, instruments and mechanical components. |
The cooler box is one part of the complete temperature-control system. A repeatable packout should be planned around the payload and delivery conditions.
| Step | Information to Confirm |
| 1. Payload | Product type, package dimensions, quantity, weight and loading arrangement. |
| 2. Temperature | Required transport temperature range and starting payload temperature. |
| 3. Route | Transport duration, ambient conditions, vehicle type and number of delivery stops. |
| 4. Coolant | Cold pack, ice pack or other coolant type, quantity and position. |
| 5. Internal Layout | Divider, insert, payload spacing and coolant placement. |
| 6. Validation | Confirm actual temperature performance under the intended transport conditions where required. |
There is no single universal holding time for an EPP cooler box because thermal performance depends on the complete transport configuration.
Box wall thickness and geometry
Internal volume and unused air space
Payload quantity and starting temperature
Coolant type, quantity and conditioning temperature
Placement of cold packs around the payload
External ambient temperature
Route duration
Frequency and duration of lid opening
Required final temperature range
For temperature-critical shipments, the finished packout should therefore be tested and validated under representative conditions.
Molded EPP allows the box structure to be developed around the product and delivery workflow rather than forcing the payload into a generic container format.
