Insulated coolers keep food and drinks cold and come in various sizes and styles, from reinforced Styrofoam to plug-in coolers. They were developed in Australia and have at least two layers of non-conductive material to prevent heat transfer. They are great for picnics and camping and come with ice packs to increase their effectiveness.
An insulated cooler is a portable container with a layer of insulation to ensure it keeps cold foods really cold. There are several styles of insulated coolers, ranging from reinforced Styrofoam versions, designed for one or two uses, to plug-in coolers that draw on electricity from a car or generator to boost their refrigeration capabilities. . Many markets sell insulated coolers, especially during the summer when people want coolers for camping and picnics.
Humans have tried to keep food fresh for centuries, both because heat increases the rate of decomposition and because many foods taste more pleasant when cold. The coolers appear to have been developed in Australia, which has a notoriously hot climate and fun-loving population. A typical cooler has at least two layers of material, which can be spaced apart with air. The air acts as a decent insulator, keeping the contents of the cooler at a fixed temperature. A cooler is usually advertised as “insulated” when extra insulation has been added.
An additional layer of insulation can be made from a variety of materials. Generally, an insulated cooler has a layer of non-conductive material that prevents heat transfer from the outside of the cooler to the inside. Many insulated coolers are made from soft, flexible materials, making them easy to transport and handle. In some cases, a freezer cooler bag can be designed so that the cooler can be brought down to a low temperature before the food is even placed inside.
An insulated cooler is great for beverage storage, as cold drinks are often at a premium in warm weather. Beer, wine and soft drinks all tend to suffer in extreme temperatures and if kept in an insulated cooler, they will be kept cold and refreshing. Such coolers can also be used for fruit, cheese and meat on picnics, ensuring they stay healthy.
When selecting an insulated cooler, you need to think about how you plan to use it. Insulated coolers come in a range of sizes, from slip-on bags designed to chill a single bottle of wine to large bags intended for packing a beach picnic. A hard cooler can keep foods cold more effectively, with a dense layer of heavy insulation, but it will be bulky and difficult to manage. Some coolers also come with ice packs designed to fit them, increasing their ability to keep food fresh.
