Can HPMC empty capsules use moisture-proof capsule materials?

HPMC empty capsules can use moisture-proof capsule materials when it is necessary to improve capsule stability and extend product shelf life. HPMC itself is sensitive to moisture, and prolonged exposure to a humid environment may cause the capsule to absorb moisture, leading to expansion, softening, or deformation, which can affect the integrity of the capsule and the quality of its contents. To overcome this issue, manufacturers can add a moisture-proof layer or use moisture-proof coating technology in HPMC capsules to enhance their moisture resistance. For example, some HPMC capsules use special composite materials or coating techniques to provide a certain degree of moisture resistance on the surface of the capsule, thereby reducing the impact of moisture on the capsule.

These moisture-proof treatments can not only help maintain the shape and stability of the capsules, but also prevent damage to the contents due to humid environments, especially in situations that require long-term storage. Moisture resistant coatings can usually effectively isolate moisture in the air, keep capsules dry, and ensure the activity and efficacy of the ingredients inside the capsules. This type of treatment can ensure that HPMC capsules can maintain their optimal performance even in high humidity environments and reduce quality issues caused by moisture absorption. The use of moisture-proof capsule materials is an effective method to ensure the stability of HPMC empty capsules in humid environments.
