Hey there! As a supplier of large empty capsules, I've seen firsthand how crucial proper storage is. Whether you're a small business owner looking to fill your own supplements or a large-scale manufacturer, getting the storage right can save you a lot of headaches and money in the long run. In this blog, I'll share some tips on how to store large empty capsules properly.
Understanding the Basics of Capsule Composition
Before we dive into storage, it's important to understand what large empty capsules are made of. Most of the capsules we supply are Empty Gelatine Capsule. Gelatin is a protein-based substance derived from animal collagen. It's a popular choice because it's easy to work with, dissolves well in the body, and has a neutral taste.
Some of our customers also prefer Green White Capsule, which are just a specific color combination of gelatin capsules. And for those who need to fill their own capsules, we offer Fillable Gelatin Capsule.
Gelatin capsules are sensitive to environmental factors like temperature, humidity, and light. These factors can affect the integrity of the capsules, causing them to become brittle, sticky, or even moldy. So, proper storage is key to maintaining their quality.
Temperature Control
The first thing you need to consider when storing large empty capsules is temperature. Gelatin capsules are best stored at a cool, consistent temperature. Ideally, the temperature should be between 20°C and 25°C (68°F and 77°F).
If the temperature is too high, the capsules can soften and stick together. This can make them difficult to separate when you're ready to fill them. On the other hand, if the temperature is too low, the capsules can become brittle and break easily.
Avoid storing the capsules in areas that are subject to temperature fluctuations, such as near windows, heaters, or air conditioning vents. A climate-controlled storage room or a dedicated storage cabinet is a great option. If you don't have access to these, you can use a simple thermometer to monitor the temperature in your storage area and make adjustments as needed.
Humidity Management
Humidity is another important factor. Gelatin capsules absorb moisture from the air, and high humidity can cause them to swell, become sticky, or develop mold. The ideal relative humidity for storing gelatin capsules is between 35% and 55%.
To control humidity, you can use a dehumidifier in your storage area. This will help remove excess moisture from the air. You can also use moisture-absorbing products like silica gel packets. Place a few silica gel packets in the container where you're storing the capsules. These packets will absorb any moisture that might otherwise affect the capsules.
On the other hand, if the humidity is too low, the capsules can dry out and become brittle. In this case, you can use a humidifier to add a little moisture to the air. Again, use a hygrometer to monitor the humidity levels and make sure they stay within the ideal range.
Light Protection
Gelatin capsules are also sensitive to light. Exposure to direct sunlight or strong artificial light can cause the capsules to degrade over time. UV rays can break down the gelatin, making the capsules weaker and more prone to damage.


Store the capsules in a dark place, such as a closed cabinet or a storage box. If you're using clear containers to store the capsules, make sure they're kept in a dark area or covered with a light-blocking material. You can also use opaque containers to protect the capsules from light.
Proper Packaging
The way you package the capsules can also affect their storage. When you receive the capsules from us, they're usually packed in sealed bags or containers. It's important to keep them in these original packages as much as possible. The packaging is designed to protect the capsules from environmental factors.
If you need to transfer the capsules to another container, make sure it's clean, dry, and airtight. Avoid using containers that have previously held substances that might contaminate the capsules. You can also use resealable plastic bags or airtight plastic containers for short-term storage.
Rotation and Inventory Management
Another tip is to practice proper inventory management. Use the “first in, first out” (FIFO) method. This means using the oldest capsules first. This helps ensure that the capsules are used before they have a chance to degrade.
Regularly check your inventory for any signs of damage or spoilage. If you notice any capsules that are sticking together, are brittle, or have mold on them, remove them from the inventory immediately. This will prevent the problem from spreading to the other capsules.
Conclusion
Proper storage of large empty capsules is essential for maintaining their quality and integrity. By controlling the temperature, humidity, and light, and using proper packaging and inventory management, you can ensure that your capsules are in good condition when you're ready to use them.
