Food containers come in all kinds of sizes and made from a variety of materials. Sometimes keeping food cold in a cooler can be a challenge, and instead of buying bags of ice, freezing water in a food container can be a good substitute for ice cubes or blocks of ice. Besides not melting into the cooler, a food container can be used repeatedly, eliminating the expenses associated with keeping food cold.

Food containers for ice packs need to have tight fitting lids so that they do not leak into the cooler. Some plastics get brittle when frozen, so choosing the types that do not break easily is the first step in using a food container in a cooler. Food containers that have been manufactured for freezing and microwaving should be sturdy enough to stand up to frequent freezing. Besides the plastic food containers, glass jars can also be used successfully as ice packs if the lids are tight fitting.

When liquids are frozen, they increase in size, so the food container should not be filled all the way to the top to allow for expansion. If there is too much liquid in a container, the top may pop off, or in the case of glass jars, could actually break the glass. Other precautions to take when using food containers to freeze liquids are to make sure the container’s lid is on tightly and it sits flat in the freezer so that the liquid inside is evenly distributed as it freezes.

Besides using water to create ice, the food container can be filled with juice or other beverages. As they thaw, they can be consumed. Besides having an inexpensive source of ice packs for a cooler, this makes the best use of space in a cooler if space is tight. When the contents of the food container will actually be consumed, making sure they are clean before the food is added will ensure that the food can be safely eaten.

Is cold pack exothermic or endothermic?

Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.
