How does the red and black HPMC capsule ensure the quality of drug encapsulation with its toughness and advantage over high-water content drug powder?

Toughness of red and black HPMC capsule
HPMC (hydroxypropyl methylcellulose) hollow capsules are made of plant material HPMC additives and appropriate excipients, and have the characteristics of low water content and strong toughness. This toughness mainly comes from the physical properties of HPMC materials, which enables the capsules to withstand certain mechanical pressures during filling and transportation without being easily broken.
High strength: HPMC materials have high tensile strength and tear strength, making the capsules not easy to break when subjected to external forces.
Adhesion resistance: HPMC capsules have the characteristics of preventing deformation or adhesion, and can maintain a stable shape even in humid or high temperature environments.
Good elasticity: HPMC capsules have a certain elasticity and can adapt to the filling of drugs of different shapes and sizes, while reducing the risk of breakage during filling and transportation.

Advantages for high-water content drug powder
Strong anti-hygroscopicity: HPMC capsules have low water content and strong anti-hygroscopicity, which can effectively prevent high-water content drug powders from caking or deteriorating due to moisture absorption during filling and storage.
Protect drug stability: HPMC, as an inert material, does not contain substances such as amino acids, which can avoid cross-linking reactions or Maillard reactions with drugs, thereby protecting the stability and effectiveness of drugs.
Suitable for filling Chinese medicine: The low moisture and high toughness characteristics of HPMC capsules are particularly suitable for filling Chinese medicine. Chinese medicine usually contains high moisture and volatile components. HPMC capsules can provide good protection to ensure the stability of drug quality during storage and transportation.
