Highly-insulated Plastic Bulk Containers (PUR insulated)
High-insulation Plastic Bulk Containers are suitable where high insulation demands are made, for example when no cooling equipment is available or in conditions where the temperature is either very high or very low. The high insulation plastic bulk container will keep the content at a stable temperature or, when needed, at a temperature as low as approximately -18°C. A high-insulation plastic bulk container is an especially good option for storing fresh fish or other products on ice or liquid ice in order to maintain their initial quality and thus maximize their value. We recommend using ice made from freshwater because seawater ice can make the contents freeze. The appropriate amount of ice depends on conditions such as temperature and intended storage time. The general rule is that approximately 30 to 40% of the content should be ice. This, however, depends on external conditions. The high-insulation type is lighter than the heavy-duty type and is therefore preferable where containers need to be moved manually. The polyurethane (PUR) foam insulation between the PE walls of the container is the key to the insulating properties of the high-insulation type. The average density of insulation is 43 g/l (kg/m3). Thermal conductivity λ~0.023W/mK.
