How to use the correct food vacuum packaging bags

Food vacuum packaging bags use the principle of oxygen removal to effectively prevent food spoilage, maintain its color, aroma, taste and nutritional value of the role. In the food industry is widely used, then, how to use the correct food vacuum packaging bags?
1. Storage precautions
Gas moisture in the air, for the packaging material is permeable, the permeability coefficient and the temperature has a close relationship, in general, the higher the temperature, the greater the permeability coefficient, the more serious the permeability of the packaging material. Therefore, for vacuum packaging bags of food, must be placed in low-temperature storage, if placed in high-temperature storage, will seriously affect the permeability of the bag, so that food deterioration. General vacuum-packed food is placed below 10 ℃ for storage.
2. Operation precautions
2.1. First of all, we should pay attention to the food vacuum packaging bags heat sealing, pay attention to the sealing parts do not stick to grease, protein, food and other residues, to ensure that the seal can be fully heat sealed.
2.2. For vacuum packaging over the bag heating sterilization treatment, should be strictly controlled sterilization temperature and sterilization time, to avoid excessive pressure inside the bag due to high temperature, resulting in the bag sealing separation, rupture.
2.3. Food vacuum packaging bags must be completely pumped, especially for fresh meat and food vacuum packaging without shaping, not residual gas, to prevent the residual gas caused by the vacuum packaging bags of food spoilage.
3. The scope of application notes
Food vacuum packaging is not suitable for the products are those fragile food, if these foods with angles, it is easy to poke the bag, penetrate. Therefore, it is best not to use vacuum packaging of such foods, using other packaging, such as gas-filled vacuum packaging bags.
