Because of their special properties, heavy duty containers are especially recommended for use in the processing, storage and transportation of meat and poultry, as well as in salt fish processing, marinating of shrimp and elsewhere in the fishing industry. They are made of one material throughout and are therefore recyclable. They are completely solid, which prevents them from collecting impurities. Their smooth and curved surface is easy to clean and drainage holes boost hygiene even further.The insulating properties of PE insulated pallet containers are considerably lower than those of the PUR insulated type, making them more suitable to use where cooling equipment is available. On the other hand, being made of PE throughout, means that heavy-duty pallet containers are extremely steady.The average density of insulation is 180 g/l (kg/m3).
