Polystyrene Containers

Dry Ice Polystyrene Containers for Sale

 

We provide a selection of high-quality polystyrene containers for sale, which are the ideal option for storing dry ice.

Polystyrene is an incredibly lightweight and robust polymer. This is what differentiates it from other forms of food storage and packaging. In addition to being extremely resilient despite its low weight, it also serves as an excellent insulator. This is an absolute delight for preserving the quality and safety of food by preventing spoilage and maintaining the appropriate temperature.

When it comes to transporting food for events or taking it with you on outdoor adventures like fishing, camping, or hunting, polystyrene is widely considered the most convenient and economical option. Industrially packaged dairy, meat, fish, and poultry are often transported in polystyrene containers. 

Polystyrene coolers are durable and can be used multiple times. In addition to being convenient for transporting frozen food purchases, they are also easy to carry and therefore useful for outdoor vacations. Only five percent of foam packaging contains polystyrene; the rest is air.

Cooler boxes made of polystyrene serve a wide variety of purposes. It has the ability to keep both hot and cold beverages and foods at their optimal serving temperatures. The polystyrene foam lining keeps the contents from spoiling and keeps the temperature stable. With its millions of tiny air bubbles, the polystyrene acts as a good insulator.

 

Polystyrene and temperature

 

Because they conduct heat, cold items eventually become warm. On a hot day, a cold drink in a can will get warm because the can is conducting heat from the environment, whereas a coffee mug will become warm because it is conducting heat from the hot coffee that you have just poured into it. Because it is a poor heat conductor, polystyrene helps to keep objects at a cool temperature. To put it another way, it takes a long time for heat to infiltrate the material, which means that it maintains the temperature for a longer period of time. This is due to the fact that gases are poorer conductors of heat than solids or liquids, and the structure of polystyrene is filled with billions upon billions of minuscule air bubbles. Polystyrene, therefore, combines the fundamental qualities of a solid with some of the insulating characteristics of a gas, creating a new type of material that has both types of characteristics.

 

Why Choose Polystyrene Containers?

 

1. Superior Thermal Performance

Polystyrene has an exceptionally low thermal conductivity (0.033–0.038 W/m·K according to ISO 8301 standards). This makes it ideal for maintaining cold-chain integrity during storage and transit. In South Africa, studies by the Council for Scientific and Industrial Research (CSIR) confirm that insulated packaging can extend product shelf life by 30–50%.

 

2. Hygienic and Food-Safe

Our containers are manufactured from expanded polystyrene (EPS), which complies with international food-safety standards. The smooth, non-porous surface prevents bacterial growth, making it suitable for seafood, meat, dairy, and pharmaceutical transport.

 

3. Lightweight, Strong and Cost-Effective

EPS packaging is 98% air and only 2% material, drastically reducing shipping weight while maintaining rigidity. This cuts down on transport costs—an important factor in cross-border trade across Namibia, Botswana, Zimbabwe, and Mozambique.

 

4. Versatile Sizes for Every Application

From small berry boxes to 30kg fish boxes and medical containers, we stock a full range tailored for agriculture, healthcare, hospitality, and industrial needs. Our 360L and 760L Cryo Bins are particularly valued in large-scale food and pharmaceutical logistics.

 

5. Reusable and Recyclable

Contrary to common misconceptions, EPS is 100% recyclable. Recycling initiatives are growing across South Africa, Namibia, and Botswana, supported by the Polystyrene Association of Southern Africa. Many of our containers can also be washed and reused, providing further sustainability benefits.

 

Applications Across Southern Africa

 

• Agriculture: Safeguarding export-quality grapes, avocados, and berries during long-haul transport.
• Fisheries: Preserving freshness of hake, tuna, and lobster for both local and export markets.
• Pharmaceuticals: Ensuring vaccines, insulin, and other cold-chain medicines remain stable.
• Hospitality & Catering: Delivering chilled foods and beverages in demanding climates.

Industrial & Scientific: Safely handling dry ice and cryogenic materials.

 

Polystyrene and the environment

 

Because of its chemical inertness, polystyrene may be reused indefinitely, but the disposal of polystyrene coolers should be done with care. Since polystyrene takes a long time to degrade, you’ll have to throw it away in a landfill along with the rest of your trash.

Avoid discarding polystyrene is rivers or down household or stormwater drains because when polystyrene polyethylene decomposes, the tiny bits of plastic released into the environment have a negative impact on aquatic and terrestrial ecosystems. Polystyrene polyethylene, when washed ashore from boats or ships, can cause obstructions in waterways and must be disposed of appropriately.

Tip: Instead of discarding your polystyrene cooler you may want to think of upscaling and so put it to good and extended use. Build a wooden box around the container for a more permanent structure to use at your next braai. Or, if gardening is your thing, why not make a planter or line it and use it for a hydroponic garden?

FAQ’s

Are polystyrene containers recyclable in South Africa?

Yes. EPS is fully recyclable, and several recycling initiatives are supported by the Polystyrene Association of Southern Africa.

How long can polystyrene containers keep products cold?

Depending on insulation, size, and use with ice or dry ice, products can remain cold for 24–72 hours.

Are polystyrene containers safe for food?

Absolutely. EPS is approved for direct food contact by EU and FDA standards, and South Africa follows similar food-safety guidelines.

Do polystyrene containers absorb liquids or odours?

No. EPS is non-porous, preventing absorption of water, oils, or odours.
