Packaging peanuts are typically made of expanded polystyrene, which is a poor conductor of heat. This means that packaging peanuts can help prevent conduction of heat between objects they are used to protect. By creating a barrier of insulating material, packaging peanuts can reduce the transfer of heat energy through conduction, helping to maintain the temperature of the packaged items.
