As we all know, food packaged in plastic has a shelf life, ordinary packaging is shorter, vacuum packaging is longer. In fact, packaging bags of food, also have a shelf life. Good storage mode, can effectively maintain the performance of the bag, extend the shelf life. Today, giant packaging for you to extend the shelf life of aluminum foil bags.
1. Temperature. The change of temperature will affect the performance of aluminum foil bag, the temperature is too high, too low, or the temperature changes suddenly, will lead to the performance of aluminum foil bag deteriorates. Therefore, the production of aluminum foil bags should be placed in the place of temperature matters, appropriate ventilation in summer, appropriate insulation in winter, as far as possible to ensure that the aluminum foil bags in the environment of small temperature difference. Do not put them in direct sunlight, because intense ultraviolet radiation will speed up the packaging aging. In addition, when summer comes, indoor walls will appear because of dampness, aluminum foil bags will also appear such a phenomenon. When storing the aluminum foil bag, do not let the aluminum foil bag close to the wall, leave about 1 cm, so as to avoid moisture.
2. Humidity. The humidity in the air will also affect the function of the aluminum foil bag. In the humid environment, the air is not circulated, which is easy to breed bacteria, resulting in the odor of the aluminum foil bag. It will also accelerate the aging of aluminum foil bag, resulting in the decrease of material flexibility, brittleness, and more easy to damage. Therefore, the aluminum foil bag should be stored in a dry, ventilated environment to avoid the rain.
Finally, even if the aluminum foil bag is properly preserved, it will naturally age and degrade its performance. It also has a shelf life. Therefore, the aluminum foil bag that has not been used for a long time should be carefully checked before use, including whether there are cracks, whether there are layers, whether there are peculiar smells, whether the physical properties are good, etc., to ensure that the bag is qualified to be put into the market.
