Description

Nitrogen-filled food packaging bag with prolonged shelf life

Technical Field

The utility model relates to a food package field specifically is a nitrogen-filled formula food package bag of extension shelf life.

Background

In order to preserve freshness and corrosion of food, the food is usually filled into a prepackage (packaging bag, can and the like) and then vacuumized and sealed or filled with inert gas (nitrogen, carbon dioxide and the like) for treatment, so that the food can be isolated from oxygen and cannot contact with the outside air, and the purpose of preserving freshness and corrosion can be achieved. As shown in fig. 1, the conventional form is: filling and blanking-a vacuum packaging form (hereinafter referred to as an A form) of vacuumizing and sealing, or a nitrogen-filled packaging form (hereinafter referred to as a B form) of filling and blanking-sealing after filling inert gas; these two packaging forms have different problems: for example, taking the traditional food of strong-smelling preserved bean curd as an example, the bean curd in the bag can be directly flattened by using the A form, so that the food form is completely destroyed, and the consumption experience is greatly influenced; in the form B, the food shape can be well preserved, but the influence of the packaging material (the influence of oxygen permeability) can cause that the freshness-retaining and preservative purpose of the product is not as expected.

The vacuum nitrogen-filled package can keep the freshness of the product, and no matter the food or the electronic product needs to be treated by moisture resistance, drying, vacuum and the like. For example: paper, even plastic, has fine pores, which can expand with heat and contract with cold when placed in a general environment, and in addition, when the air contains more moisture, the paper can absorb the moisture and when the air is dry, the moisture of the paper can be evaporated into the air for a long time, and the paper can turn yellow and deteriorate. However, air is not water alone, but bacteria, mold, impurities, and the like are also present, and vacuum nitrogen flushing is required to maintain quality.

Snacks and foods sold in the market at present are packaged in a nitrogen vacuum mode, so that the foods are prevented from deteriorating, the shelf life can be prolonged, but if air leaks, the foods are damaged, and therefore the nitrogen-filled food packaging bag with the prolonged shelf life is provided.

SUMMERY OF THE UTILITY MODEL
