Main effect


The main functions of vaccum pack bags are not only deoxidizing and keeping quality, but also resisting pressure, blocking gas and keeping fresh, which can more effectively keep the original color, aroma, taste, shape and nutritional value of food for a long time. In addition, many foods are not suitable to use for vacuum packaging, but must be packed by vacuum aeration. Such as crisp and fragile food, easily deformed and oily food, and food with sharp edges and corners or high hardness that will puncture the packaging bag. After the food is packed in food saver vaccum, the inflation pressure inside the packaging bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure without affecting the appearance and printing decoration of the packaging bag.


The strong vacuum storage bags are filled with single gas of nitrogen, carbon dioxide and oxygen or mixed gas of two or three gases after vacuum. Nitrogen is an inert gas, which plays a filling role to keep positive pressure inside the bag, so as to prevent air outside the bag from entering the bag and protect food.
