EVOH Oxygen Barrier PP MAP Trays Meat Tray

Modified Atmosphere Packaging

The names of modified atmosphere packaging include MAP (modified atmosphere packaging), CAP (controlled atmosphere packaging).active packaging, etc. In order to unify the understanding of modified atmosphere packaging technology, the international food packaging industry defines modified atmosphere packaging as "by changing the atmosphere in the package, the food is in an atmosphere different from the air components (78.8%N2, 20.96%O2, 0.03%CO2)" Packaging that extends the shelf life in the environment”, all packaging technologies that meet this definition are called MAP or CAP. EVOH Barrier MAP Tray is a widely used modified atmosphere packaging tray.Evoh High Barrier Tray can maintain the atmospheric ratio inside the package for a long time, inhibit cell respiration without destroying cells, prevent the oxidation of vitamins and red blood cells, not only retain the nutrition of meat, but also maintain the competitiveness of the product Appearance.

Why choose MAP Trays

Modified Atmosphere Packaging (MAP) is a packaging system that involves changing the gaseous atmosphere surrounding the food within the package, and using packaging materials and formats with appropriate levels of gas barrier to maintain the changed atmosphere at acceptable levels to Preserve food.

The shelf life of a food product can be defined as the period during which the product is still available for human consumption. Shelf life is determined by microbiological, chemical and physical aspects. Because of these aspects, consumers may reject the product based on its sensory profile. In most cases, shelf life is determined by a combination of raw material quality, product formulation, processing, packaging, and storage conditions. Special attention should be paid to storage conditions, as temperature and oxygen levels may accelerate or delay chemical reactions and microbial growth. Storage temperature directly affects enzymes. Enzymatic activity in foods can cause changes in the chemical composition of the product, resulting in changes in flavor, odor, color and texture. The amount of oxygen may aggregate chemical reactions that lead to oxidation.

Modified atmosphere packaging (MAP) isolates the food from the outside air by sealing, and replaces the internal environment of the MAP with the gas that can preserve the food, inhibits cell respiration without destroying cells, reduces the metabolic rate of cells, and delays food. Oxidation process of nutrient elements, so as to achieve the purpose of food preservation, and the effect is better in low temperature environment. Of course, once the food leaves the MAP, the food (like fresh meat) regains its metabolic rate and regains its color and brightness.
