Modified Atmosphere Packaging
Modified atmosphere packaging (MAP) is used for packaging fruits and vegetables to prolong their shelf life and preserve their quality effectively. Fruits and vegetables undergo respiration even after being harvested, whereby oxygen is continuously consumed, and carbon dioxide and water vapour are produced, resulting in detrimental effects.
Gas Flushing Packaging
MAP film eliminates oxygen within the enclosed space of the product packaging while concurrently preventing water evaporation. When implementing MAP, the exchange of oxygen and carbon dioxide occurs between the inside and outside of the package, ensuring that the oxygen consumed within the package is replenished by the oxygen outside while simultaneously maintaining a constant level of carbon dioxide.
This establishes an equilibrium and effectively prevents moisture loss and the natural production of ethylene gas released by the fruits or vegetables, slowing the ripening process.
Fresh Produce Preservation
Oxygen, Carbon Dioxide, and Nitrogen are commonly introduced into the packaging to establish a safe and balanced extension of the product’s shelf life.
Gas flushing packaging reduces waste, preserves freshness, and prevents infestations by insects, parasites, and moulds. Controlled atmosphere packaging can be applied in various forms, such as bulk liners, preformed retail packaging, roll stock for flow pack application, and film forms in rolls.
