Gas flushing of the packaging materials or pouches is a technique used for prolonging the shelf-life period of minimally processed or fresh foods. In packaging with the blow mold containers; the air surrounding the food inside the package is customized or changed. In blow mold containers, the oxygen inside the pouch is removed and replaced with an inert gas for instance, carbon-di-oxide and nitrogen etc. The blow mold containers are engineered and manufactured with coextruded films, this is done by applying a combination of PA (Nylon) between PE (Polythene) on the outer side, whereas inside there are sealing layers of modified PE.

The saran (P.V.D.C.) barriers designed to seal the gas in, protect the color of the food to be stored in the blow mold containers; making them suitable for applications in the food & beverage industry. The blow mold containers these days are compatible with most of the snorkel type of blow mold containers filling machines. They are also compatible with Gas Flushing (CVP) or Modified Atmosphere Packing (MAP) type machines. The blow mold containers are also known as bulk blow mold containers.
The need for packaging solutions with a good puncture resistance is fueling the growth of the blow mold containers market. The growing demand for packaging pouches suitable for wet as well humid environments is also a driving factor. The demand for packaging solutions to maintain the red color of the meat another driving factor; carbon monoxide is used to maintain the red color of any kind of meat when flushed inside the pouch instead of oxygen. However, the concerns for global warming coupled with the excessive use of plastic for manufacturing blow mold containers; is a restraining factor for the growth of its market.
The feature of blow mold containers that facilitates in sealing through contamination and folds, is widening the scope for the growth of its market. One of the prominent trend in the global gas flush pouch market is the availability of the customization as per the specific needs of the consumer. Another prominent rend is that many blow mold containers have a good moisture as well as oxygen barrier.
The global blow mold containers market geographically is segmented as North America, Eastern Europe, Western Europe, Latin America, Asia-Pacific excluding Japan, Japan, and Middle East & Africa. North America and Europe hold a significant market share of blow mold containers market owing to the fully developed packaging technologies.
