Expanded polystyrene (EPS) packaging is widely used in the food, health and pharmaceutical industries because of its superior insulating and protective properties, ensuring the product quality and safety for storage and transportation.
In this post, we look at the main properties of EPS cooler boxes.
Maintains Temperature Constant
Any increases in temperature are detrimental to the quality and safety of packaged food or medicine. Maintaining a constant temperature during storage and transportation is important to guarantee product quality and safety for consumption – think of perishables, fresh meat, fresh seafood or ice cream.
EPS (expanded polystyrene) has a very low rate of thermal conductivity compared to packaging alternatives made of wood, paper, cardboard or polyethylene film. It means the insulating performance of EPS is higher compared to conventional packaging materials, and it explains why EPS packaging is ideal where thermal insulation is needed.
EPS cooler boxes can be used to keep products at even or below surrounding temperatures and to protect contents against sudden temperature changes and thermal shocks caused by product transfers or removal from refrigerator trucks or cold rooms.
The Isowall Group has been manufacturing and distributing Isolite Shape Moulded EPS since 1992. Isolite Shape Moulded EPS Products are manufactured using customised moulds providing a wide range of uses including insulation, lightweight fillers and semi-rigid cushioning. This involves manufacturing a customized mould for the product to be manufactured and then producing products as needed.
Protects Against Damage
The insulation properties of EPS packaging and cooler boxes not only ensure optical temperature conditions but also help prevent bacterial deterioration and external contamination. Products are preserved in ideal thermal and hygienic conditions.
EPS packaging also helps protect the product against mechanical deterioration due to improper manipulation and transportation, unlike conventional packaging material susceptible to breakage.
The outstanding thermal and protective properties of EPS cooler boxes offer a reliable and cost-effective packaging option for fresh produce, meat, fish, as well as temperature-sensitive medicine.
By maintaining temperature stability and enforcing protective barriers, EPS cooler boxes assist producers to meet strict industry regulatory requirements, quality and safety criteria.
