Is it necessary to use airtight packaging materials when storing HPMC empty capsules?

It is very important to use non breathable packaging materials when storing HPMC empty capsules. HPMC capsules are sensitive to changes in humidity and temperature. If exposed to excessive moisture or air, they may absorb moisture, causing softening or expansion, which affects the physical properties and stability of the capsules. Using non breathable packaging materials such as aluminum foil bags, vacuum packaging bags, or sealed containers can effectively prevent external air and moisture from entering the capsule, thereby maintaining its integrity.
Non breathable packaging materials not only prevent changes caused by moisture, but also help maintain the dryness of the capsules and prevent increased brittleness due to dehydration. Especially in environments with large fluctuations in temperature and humidity, appropriate packaging materials can effectively isolate the influence of external environment, maintain the stability of capsule quality, and avoid performance degradation due to long-term storage or transportation. Therefore, using non breathable packaging materials is a key step in ensuring the long-term stability and non damage of HPMC empty capsules.
