- Immune system function
- Overall health and well-being
By providing a balanced and nutritious diet, MREs help soldiers maintain their physical and mental health, allowing them to perform their duties effectively and efficiently, even in challenging conditions.
Packaging and Durability
MREs are designed to withstand the rigors of military operations, including extreme temperatures, moisture, and physical stress. The packaging plays a crucial role in preserving the integrity and nutritional value of the food inside.
The outer packaging of an MRE consists of a durable, flexible plastic pouch. This pouch is typically made of a material such as polyethylene or polypropylene, which provides excellent resistance to punctures and tears. The pouch is sealed with a moisture-proof zipper, ensuring that the contents remain dry and protected from contamination.
Materials and Construction
- Polyethylene or polypropylene outer pouch
- Moisture-proof zipper
- Inner foil or plastic liner
- Desiccant packets to absorb moisture
Inside the outer pouch, the food items are individually packaged in smaller pouches or containers. These inner packages are typically made of foil or plastic, which provides additional protection against moisture and oxygen. Some MREs also include desiccant packets to absorb excess moisture and prevent spoilage.
Shelf Life
The shelf life of an MRE depends on the specific contents and packaging methods used. Most MREs have a shelf life of 3-5 years when stored at room temperature. However, some MREs designed for extended storage or extreme environments may have shelf lives of up to 10 years or more.
