High-Quality Polystyrene Containers for South Africa

Dry Ice International, a trusted leader in cold chain solutions since 1994, supplies high-quality expanded polystyrene (EPS) containers across South Africa, serving key hubs like Cape Town, Johannesburg, Durban, and Pretoria.

Our lightweight, customizable containers are designed for agriculture, pharmaceuticals, and hospitality, ensuring safe transport of perishables such as fresh produce, seafood, and vaccines.  

South Africa’s agricultural sector, contributing 2.5% to GDP (Stats SA, 2023), relies on efficient cold chain logistics to support R90 billion in annual exports. Paired with dry ice at -78.5°C, our containers maintain temperatures for 18–24 hours. 

Our EPS containers minimize heat transfer through convection and conduction, reducing cooling costs by up to 30%. Available in various sizes and shapes, they cater to diverse needs, from medical logistics in Gauteng to citrus exports in the Western Cape, ensuring product integrity in South Africa’s varied climates. 

Polystyrene coolers are low-cost and simple to produce in large quantities. Since they are inexpensive, they can be used only once or twice before being thrown away without causing significant financial impact.

Polystyrene coolers can be customised with a wide range of shapes and sizes to meet your requirements. Shop polystyrene containers for sale in our online store.

They are the industry’s lightest cooler option. You might also be interested in our range of cooler boxes for sale and dry ice in Cape Town.

Adding ice to polystyrene containers

The ratio of ice to contents that is usually regarded is approximately 2:1. The pace at which ice melts is proportional to the amount of surface area it has: A large ice block melts at a significantly slower rate than the same quantity of ice broken up into smaller cubes.

To achieve best results over a longer period of time, you may want to consider using dry ice. Approximately 18 to 24 hours of storage time can be expected for dry ice in a standard polystyrene cooler. Dry ice may keep its cold for three or four days if it is stored in a large enough cooler and multiple blocks are utilised in conjunction with one another. Since its founding in 1994, Dry Ice International has dominated the South African and African markets for dry ice production and delivery.

Dry ice, which is frozen carbon dioxide, has a temperature of -78.5°C, making it far colder than conventional ice, which has a temperature of 0°C. Dry ice is significantly colder than a typical freezer, which is usually set to a temperature of -18°C. There is no melting or other messy process involved because dry ice instantly changes from a solid to a gas.

There will be a direct correlation between the quantity of product you want to keep frozen and the quantity of dry ice required. A large quantity of dry ice and a negligible amount of food will stay cold for a very long time, but at a high expense. On the other hand, if you combine a small amount of dry ice with a large quantity of food, you won’t have much of either for very long.

Dry ice will dissolve more quickly if placed on the top of the cooler, as opposed to the bottom. This is due to the fact that dry ice warms up more quickly near the top of the cooler, where it is exposed to more heat, and because cold air lowers, away from the dry ice. Since less heat will be able to reach the dry ice if it is placed near the base, it will last longer. When you’re trying to extend the shelf life of dry ice, empty space or air is your enemy. Dry ice will stay longer in a smaller cooler with less air space than in a larger cooler with more air space, assuming the amount of dry ice is the same in both coolers. Dry ice dissolves more quickly when exposed to air.

Dry ice can be preserved for somewhat longer if it is stored in the plastic bags it comes in, as the plastic also acts as an insulator. In addition, dry ice can be preserved for extended periods of time if it is wrapped in newspaper or if cardboard is placed on both the top and bottom of the dry ice blocks.

Why Choose Dry Ice International for Polystyrene Containers

Dry Ice International sets the benchmark for cold chain solutions in South Africa with high-density EPS containers that offer superior insulation and affordability. Compliant with the National Environmental Management Act (NEMA), our containers ensure safe dry ice handling and eco-friendly disposal, aligning with South Africa’s sustainability goals. With a 98% customer satisfaction rate across 80+ clients (2025 internal survey), we address challenges like load shedding and rising logistics costs, critical for South Africa’s R1.5 billion cold chain market (SADCLA, 2024). 

Our containers support critical applications, such as vaccine distribution for 25% of South Africa’s population (SAHPRA, 2024) and fresh produce transport for markets like Cape Town’s Epping Market. Lightweight and durable, they reduce transport costs, with packaging imports projected to decline 5.8% by 2026 due to local solutions (ReportLinker).

Where Dry Ice International Serves South Africa

Our polystyrene containers are utilized across South Africa’s key regions, including Cape Town’s fishing industry, Johannesburg’s pharmaceutical hubs, Durban’s export ports, and Limpopo’s agricultural zones. South Africa’s cold chain, supporting 10% of agricultural exports, faces challenges like unreliable power, with 60% of businesses affected by outages. Our containers ensure temperature stability for perishable goods in markets like Tshwane Market, supporting sectors from dairy to medical logistics in rural clinics. 

How Dry Ice International Delivers Polystyrene Containers 

We offer a free consultation to customize EPS containers for your needs, from small medical transport units to large food storage boxes. Using a 2:1 ice-to-content ratio, our containers maintain sub-zero temperatures for 18–24 hours, or up to 3–4 days with multiple dry ice blocks (Packaging News, 2024). High-density EPS foam minimizes heat ingress, ideal for South Africa’s warm summers, averaging 30°C in coastal areas. Dry ice placed at the container base extends cooling by reducing sublimation, as cold air sinks. 

Our robust logistics network ensures timely delivery across South Africa, overcoming challenges like port delays. Compliant with NEMA regulations, our containers use eco-friendly EPS, supporting South Africa’s Waste Management Strategy. Prefabricated designs cut installation costs by 20%, making them ideal for cost-conscious businesses in Johannesburg and beyond.
