Custom Transparent PA Food Vacuum Co-extrusion Nylon Packing Bag

The main function of vacuum inflatable packaging is not only the deoxygenation and quality preservation function of vacuum packaging, but also anti-compression, gas blocking, and fresh-keeping, which can more effectively keep food in its original color, aroma, taste, shape and shape for a long time. nutritional value. In addition, there are many foods that are not suitable for vacuum packaging and must be vacuum inflated. Such as crunchy and fragile food, food that is easy to agglomerate, food that is easily deformed and oily, food with sharp edges and corners or high hardness that will pierce the packaging bag, etc. After the food is vacuum-packed, the inflation pressure inside the bag is stronger than the atmospheric pressure outside the bag, which can effectively prevent the food from being crushed and deformed under pressure without affecting the appearance and printing and decoration of the bag. The vacuum inflatable package is filled with nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after vacuum. Its nitrogen is an inert gas, which plays a filling role to maintain a positive pressure in the bag to prevent the air outside the bag from entering the bag, and has a protective effect on the food. Its carbon dioxide can be dissolved in various fats or water, resulting in weak acid carbonic acid, which has the activity of inhibiting microorganisms such as mold and spoilage bacteria. Its oxygen can inhibit the growth and reproduction of anaerobic bacteria, maintain the freshness and color of fruits and vegetables, and high concentration of oxygen can keep meat fresh.
