Foil aluminum bags are widely used in various industries such as food, chemical, electronics, and pharmaceuticals due to their excellent barrier properties and stability. However, improper storage can lead to quality problems such as oxidation, brittleness, delamination, and poor sealing in even high-quality foil aluminum bags, affecting subsequent packaging performance. Therefore, proper storage is crucial for extending the lifespan of foil aluminum bags.
Foil aluminum bags should be stored in a dry, cool, and well-ventilated environment. Although aluminum foil material has moisture-proof properties, prolonged exposure to high humidity can cause the laminated material to absorb moisture and degrade its performance, thus affecting its overall barrier properties. The ideal storage humidity should be maintained between 45% and 65%, and it should be kept away from water sources or steam equipment. Simultaneously, the storage temperature is recommended to be controlled between 15 and 30°C to avoid high temperatures causing adhesive aging and composite layer peeling.
Foil aluminum bags should be protected from direct sunlight and strong light. Ultraviolet rays accelerate material aging, making the bag brittle and even causing micro-cracks. This is especially important for high-barrier bags used for food or sensitive materials, which require extra care to protect them from light during storage. In addition, foil aluminum bags should be kept in their original packaging during storage and should not be disassembled arbitrarily. Avoid dust, oil, or hard objects scratching the surface, which can impair the subsequent heat-sealing quality.
Regarding warehouse management, foil aluminum bags should be stored upright or neatly stacked flat. They should not be tilted or subjected to heavy pressure to prevent deeper creases, material fatigue, or edge deformation. For large quantities of foil aluminum bags, a first-in, first-out (FIFO) management method is recommended to avoid natural aging of the material due to long-term storage.
To extend the service life of foil aluminum bags, pre-use treatment can also be beneficial. Before sealing, moderately preheating the sealing area can improve the heat-sealing effect and reduce sealing defects caused by moisture. At the same time, the operating area should be kept clean to prevent dust or oil from affecting heat-sealing stability. For foil aluminum bags stored for more than six months, it is recommended to conduct sampling inspections before use, including observing for delamination, wrinkles, pinholes, and decreased sealing performance.
Although the storage management of foil aluminum bags may seem simple, it directly affects their service life and packaging quality. By improving the storage environment, strengthening daily maintenance, and standardizing usage procedures, the excellent performance of foil aluminum bags can be effectively maintained, ensuring optimal results in production and packaging.
