MAP barrier trays are designed to increase the shelf life of packaged products

MAP barrier trays are designed to increase the shelf life of packaged products. This packaging technique can be used to increase food security and increase profitability for retailers. MAP also helps to increase brand exposure and helps consumers maintain a healthy diet. In addition, it reduces food waste and reduces grocery store trips.

The main difference between MAP and conventional packaging is that MAP uses a gas mixture to replace air. The amount of gas that is used depends on the product that is being packaged. This technique allows for the preservation of foods without using chemical stabilizers. In addition, it increases the geographic distribution of the packaged products.

MAP trays are designed to keep moisture and oxidation from entering the package. In addition, they help to maintain proper atmosphere inside the bag. These trays can be used in a number of applications including fresh-cut fruits and vegetables, cut vegetables, salad mixes, and other food items.

MAP trays also work to reduce the growth of aerobic decomposition organisms in the package. These organisms can lead to spoilage of the product. MAP trays use an inert gas mixture to replace the air. These gases can be used alone or in combination with each other. This technique is also used in the coffee industry, as one-way valves allow certain gases to escape while preventing other gases from entering the package. MAP has also been used to extend the shelf life of fresh produce.

Most MAP trays use polyethylene, polypropylene, or polyvinyl alcohol. These materials are used in flexible packaging applications and rigid packaging applications. They have good barrier properties to water vapor, and are suitable for hot filling processes. Polypropylene is also used in semi-rigid packaging applications.

Polyvinyl chloride is another type of material used for MAP trays. This material is available in copolymers and homopolymers, and it has excellent barrier properties. EVOH is also a common gas barrier material in MAP modified atmosphere packaging applications. It has better processing properties than PVOH, and it is less sensitive to moisture. In addition, it has a lower gas barrier than PVOH. It is ideal for plastic structures, and is used in laminates for MAP thermoformed base trays.

Some MAP trays use a paperboard tray as a structural layer. This type of tray is used to protect the packaged product from tearing and can be produced in a number of shapes and colors. It can also be made from recycled materials. Some trays are even made from 100% recycled PETE, which translates to less food waste and helps to preserve food for a longer period of time.

Other types of MAP trays use one-way valves, which allow certain gases to escape from the package while preventing other gases from entering. These valves can be used in conjunction with vacuum skin packaging. These valves can also be used in combination with nitrogen, as a way to increase the shelf life of fresh produce.

MAP trays can be used in a wide variety of applications, but they are most commonly used for fresh-cut fruit and vegetables. In addition to extending shelf life, these trays also help to extend the quality of the food. These packages often contain ascorbic acid, which absorbs the ambient moisture and oxygen. It also helps to prevent discoloration and off-flavors. In addition, they can help to increase the shelf life of meat and poultry products.
