Vacuum packaging bag is a very common packaging in our daily life. It is widely used in various industries and is favored by consumers and businesses. The most common is food vacuum packaging bag. The food vacuum packaging bag uses the deoxygenation principle to effectively prevent food deterioration and maintain its color, fragrance, taste and nutritional value. It is widely used in the food industry. The following section will introduce how to correctly use the food vacuum packaging bag.


First, precautions for storage:


The gas and water in the air penetrate into the packaging materials, and the permeability coefficient is closely related to the temperature. Generally, the higher the temperature is, the greater the permeability coefficient is, and the more serious the penetration into the packaging materials is. Therefore, the food packaged in vacuum packaging bags must be stored at low temperature. High temperature storage will seriously affect the permeability of packaging bags, leading to food deterioration. Generally, vacuum packaged food is stored below 10 ℃.


2、 The second is operation precautions:


1. First of all, when heat sealing food vacuum packaging bags, pay attention not to attach grease, protein, food and other residues to the sealing parts to ensure complete heat sealing.


2. When the vacuum packaging bag is heated and sterilized, the sterilization temperature and time must be strictly controlled to avoid excessive temperature, excessive internal pressure of the packaging bag, and separation and rupture of the packaging bag seal.


3. Food vacuum packaging bags need to be completely vented. In particular, fresh meat and amorphous food cannot be vacuum packed, leaving gas residue. Prevent the food in the vacuum packaging bag from spoilage due to residual gas.


3、 Finally, matters needing attention in the scope of application:


The products that are not suitable for vacuum packaging of food are fragile food. If they have edges and corners, they will easily break the packaging bags, or even penetrate. Therefore, this kind of food should be packaged with other packaging such as inflatable vacuum packaging bags, rather than vacuum packaging.


The above is about how to correctly use food vacuum packaging bags. After reading, do you know? I hope it will be helpful to you.
