Active Modified Atmosphere Packaging tray, used for the bottom tray of the modified atmosphere packaging machine, generally made of plastic PP material. It is placed in the lower mold of the packaging mold of the Air Conditioning Packaging Machine, and the air-conditioning machine replaces the air in the air-conditioning packaging tray with fresh-keeping gas, and then presses the Tray Lidding Film, thermoplastics, cuts the film and other actions to complete the air-conditioning lock fresh packaging.
During the packaging process, the Modified Atmosphere Packaging Meat Tray needs to be replaced and filled with fresh-keeping gas, and the pressure of the gas filled during packaging is generally higher than the standard atmospheric pressure outside, so the production requirements of the modified atmosphere packaging tray are higher than that of ordinary plastic trays.
Modified atmosphere packaging tray KPI indicators
1. Good air tightness - no air leakage after inflatable packaging; 2. Environmental protection - food-grade plastic material, good thermal stability, etc.; 3. Stable compression - thermal expansion by the gas in the packaging Cold shrinkage, stable against internal stress. Tipack® is equipped with advanced German kaifil autoclave thermoforming equipment, which can highly meet the thermoforming production requirements of co-extruded EVOH or nylon high-barrier products, and can also complete asymmetric plastic sheets (plastic sheets with different materials on both sides) production of thermoformed products.
Active Modified Atmosphere Packaging and lidding film
Modified atmosphere packaging replaces the air in the tray with a fresh-keeping gas, and then performs thermoplastic sealing. It is the most effective fresh-keeping technology in the current food packaging technology. Since the gas in the MAP Trays is in a positive pressure state, the modified atmosphere fresh-keeping packaging consumables, that is, the modified atmosphere packaging tray and lidding film, have high barrier properties and are made of PP food grade.
With the large-scale application of modified atmosphere fresh-keeping packaging machines in food industry, the procurement demand for its supporting consumables (such as: modified atmosphere packaging films, modified atmosphere packaging boxes) has also shown a strong trend.
Food safety has always been the focus of consumers' attention. In addition to its own material, food quality also involves the quality of its Vacuum Skin Packaging consumables, such as PP tray, Shrink Bag, Lidding Film, etc. Food-grade packaging plastic consumables are generally required to be PP (polyphenylene) materials.
