Relying on the principle of oxygen removal, food vacuum packaging bags can effectively prevent food spoilage, and maintain its color, aroma, taste and nutritional value, and they have been widely used in the food industry. Do you know how to properly use them? If not, don’t worry, and Boya, a China vacuum packaging bags manufacturer, here offers you some tips to use food vacuum packaging bags in a proper way.
1. Storage precautions
Air moisture is permeable for packaging materials, and the permeability coefficient is closely related with temperature. In general, the higher the temperature, the greater the permeability coefficient, and the more serious the permeability of the packaging material. Therefore, the food packaged in custom vacuum seal bags should be placed and stored at low temperature, otherwise the permeability of the bag will be seriously affected and food will become deteriorated if stored at high temperature. General vacuum-packed food should be stored at a temperature below 10 ℃.
2. Operating precautions
First, when heat sealing the food vacuum packaging bags, avoid the sealing part from being stuck with grease, protein, food and other residues, so as to ensure that the sealing part can be fully sealed.
When performing heating sterilization treatment of vacuum packaging bags, strictly control sterilization temperature and sterilization time, avoiding excessive pressure inside the bag due to high temperature, and separation or rupture of the sealing part.
Food custom vacuum seal bags must be completely pumped, especially for those packaging raw meat and those without fixed shape. No residual gas is allowed, preventing residual gas leading to food spoilage inside the vacuum packaging bags.
3. Applications
Food vacuum packaging is not suitable for fragile food, which will poke or even penetrate the bag if the food has sharp edges. Therefore, you’d better not use vacuum packaging bags to package such kind of food, and choose alternative packaging bags, for example, gas-filled vacuum packaging bags.
