WHAT IS MODIFIED ATMOSPHERE PACKAGING?
MAP, or Modified Atmosphere Packaging – packaging in a modified atmosphere. This technology is also known as gas injection, protective gas packaging or oxygen controlled packaging.
This is a technology developed to maintain the freshness and aesthetics of products throughout their intended shelf life, by modifying the gas composition surrounding the product in the packaging. Modifying the atmosphere surrounding packaged foods improves color, texture and nutritional value, and is considered a minimal treatment compared to the use of chemicals, preservatives or stabilizers.
SCOPE OF APPLICATION
Today, MAP technology is widely used in food packaging such as meat, fish, seafood, cheese, bread, pasta, as well as in healthcare products such as surgical implants and pharmaceutical blister packs.
In addition to being used in food packaging, MAP is also applied to preserve the quality of pharmaceutical products and medical devices.
MAP PACKAGING PROCESS
for agricultural industry: packaging rice, agricultural products,...
MAP technology is typically achieved by blending gases such as oxygen (O₂), carbon dioxide (CO₂) and nitrogen (N₂), then packaging the food or medical product in an airtight container containing this gas mixture. Precise control of the gas composition helps to meet the specific breathing needs of each product, minimizing spoilage and extending the product's optimal shelf life.
