Empty capsules serve as a crucial carrier for pharmaceuticals and health supplements, and their quality directly impacts the safety and efficacy of the final products. Whether you are using empty gelatin capsules or vegetable capsules, improper storage can easily lead to brittleness, fragmentation, softening, deformation, or even mold growth, resulting in massive financial losses for businesses. So, how can you extend the shelf life of empty capsules? Mastering the following four core essentials is a must for every pharmaceutical and health supplement manufacturer.
1. Strictly Control Temperature and Humidity
Temperature and humidity are the top culprit affecting the lifespan of empty capsules. The moisture content of empty gelatin capsules typically needs to be maintained between 13% and 16%. An environment that is too dry (below 40% RH) will cause the capsules to become brittle, while an environment that is too humid (above 60% RH) will cause them to soften and stick together. It is recommended to store capsules in a cool, dry place, with an ideal temperature of 18℃-26℃ and relative humidity controlled between 35%-65%. For large-scale inventories, it is imperative to equip your facility with a professional constant temperature and humidity warehouse.
2. Avoid Light Exposure and Choose Premium Packaging
UV rays and strong light will accelerate the photo-oxidative aging of the capsule material, leading to yellowing and a decline in physical performance. Therefore, the storage environment must be kept away from light. At the same time, the choice of outer packaging is crucial. It is recommended to use aluminum foil bags or high-density composite plastic drums for double-layer sealed packaging, with a sufficient amount of specialized desiccant placed inside to block the intrusion of external moisture.
3. Standardize Stacking and Daily Management
During warehousing, empty capsules should be placed on pallets, and direct contact with the ground is strictly prohibited to prevent moisture absorption. The stacking height should not be too high to avoid deformation and fragmentation of the bottom-layer capsules due to excessive pressure. In addition, strictly implement the First-In, First-Out (FIFO) inventory management principle to prevent product expiration caused by backlogs.
4. Control Procurement Quality from the Source
The prerequisite for extending shelf life is that the product itself is of high quality. Choosing empty capsules produced by legitimate source manufacturers ensures more stable formulations and stronger resistance to temperature and humidity fluctuations. For inferior capsules-due to insufficient gelatin gel strength or low-purity plant extracts-even with meticulous storage, their shelf life will still be significantly reduced.
