Antifog Sealable MAP CAP Tray Lidding Film

The names of modified atmosphere packaging include map (modified atmosphere packaging) and 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 "packaging that prolongs the storage period by changing the atmosphere in the packaging to make the food in an atmosphere environment different from the air components (78.8% N2, 20.96% O2, 0.03% CO2)". All packaging technologies that meet this definition are called map or cap Modified atmosphere packaging for food preservation is not a new concept, but further developed and applied on the basis of the original concept of oxygen reducing packaging. 

Modified atmosphere packaging is a food preservation packaging technology more complex than vacuum packaging. The atmosphere in the packaging is more conducive to the preservation of all kinds of food, especially fresh food such as meat, fish, fruits and vegetables. Because modified atmosphere packaging can provide more fresh food or processed food with natural flavor and nutrition than vacuum packaging, Therefore, it has been widely used in the market since the 1980s.Map package includes tray, lidding film and filling gas. 

Tldf is a high barrier and antifogging film researched and released by tipack group to improve the overall performance of map tray packaging. The meaning of map is to improve the atmosphere of packaging, which more accurately expresses the definition of this packaging technology. The English meaning of cap is to control the atmosphere of packaging. Because the air permeability of flexible packaging materials and the interaction between food and gas in the packaging make it impossible to control the atmosphere in the packaging, it is considered to be a misnomer. Although map and cap are sometimes common internationally, modified atmosphere packaging has been gradually unified in the packaging industry as map Map is sometimes referred to as gas packaging. The package is filled with single gas, such as nitrogen, carbon dioxide and oxygen. The specific gas types and components are based on the anti-corrosion and fresh-keeping requirements of various foods. This kind of modified atmosphere packaging, which changes the atmosphere in the packaging by filling a single gas or mixed gas, is the main packaging form of food modified atmosphere packaging.
In meat preservation, C02 and N2 are two main gases. 

The existence of a certain amount of 02 is conducive to prolonging the shelf life of meat. Therefore, an appropriate proportion must be selected for mixing. In Europe, the gas ratio of modified atmosphere preservation of fresh meat is 02: C02: N2 = 70: 20: 10 or 02: C02 = 75: 25. At present, the most effective fresh meat preservation technology in the world is the modified atmosphere packaging (CAP) system with high C02 inflatable packaging.
