Foam (also known as EPS) has many useful properties. It can be used as an insulator against heat and the cold. It is good at absorbing shocks and protecting delicate items, for example your head when used as part of a cycle crash helmet.
These and other properties have led packaging technologists to specify EPS as the first choice material for packaging many products.
About Foam:
Protective
The outstanding shock absorbency and compression resistance provides excellent protection properties.
Durable
The exceptional durability of foam makes it an effective and reliable protective packaging for a wide range of goods. There is no loss of strength in damp conditions, making foam ideal for cool-chain products. The material is moisture resistant, so the highest hygiene requirements are met. Foam is also odourless and non-toxic.
Lightweight
Foam is made up of 98% air, making it a very lightweight material, its use for packaging does not significantly add to the weight of the total product. This in turn means that fuel consumption is improved and fuel emissions are lower than with heavier materials. The reduction in emissions means less impact on global warming.
Insulating
The thermal insulation properties of Foam help keep food fresh through the distribution chain. It is widely used to package fresh fish and for seed trays where it assists in the growth of the plants. It is also used by the pharmaceutical industry to package items that are temperature sensitive and that need to be transported around the world.
Versatile
Foam can be moulded into any shape or form to meet a product’s protection and insulation needs. Small amounts of foam can be used as corners for heavy items or a valuable product may be completed encased in foam to provide maximum protection.
