When we mention Pullulan Capsules, we have to mention its unique film-forming property. This capsule shell made of pullulan not only has a smooth and tough texture in appearance, but also brings us many surprises in performance. So, what is so unique about the film-forming property of Pullulan Capsules?

First of all, we need to understand that the film-forming property of Pullulan Capsules comes from the molecular structure of pullulan. Pullulan is a water-soluble polysaccharide formed by α-1,6 glycosidic bonds connecting maltotriose units. This unique structure enables it to form a uniform and dense film structure. When pullulan is processed into a capsule shell, this film-like structure can tightly wrap the internal substances and effectively isolate the external environment.

So, what are the advantages of Pullulan Capsules' film-forming property in practical applications? First, due to the long molecular chain of pullulan, the film-like structure formed has high mechanical strength, which can effectively prevent the capsule from breaking or deforming during storage and transportation. This makes Pullulan Capsules more reliable in the fields of medicine and food.

Secondly, the film-forming property of Pullulan Capsules is also reflected in its control of moisture. Pullulan has good hydrophilicity and water retention, which can control the moisture content inside the capsule to a certain extent. This characteristic enables Pullulan Capsules to effectively prevent the internal substances from deteriorating due to excessive moisture when storing moisture-sensitive substances such as medicines and foods.

In addition, the film-forming property of Pullulan Capsules also gives it good permeability and release properties. The membrane structure of pullulan has a certain permeability, which can allow small molecules such as oxygen and moisture to enter and exit freely under certain conditions. This characteristic makes Pullulan Capsules have broad application prospects in the fields of drug sustained release and nutritional supplements.

Finally, it is worth mentioning that the film-forming property of Pullulan Capsules is also reflected in its environmental protection. Since pullulan is a natural polysaccharide with good biocompatibility and biodegradability, Pullulan Capsules will not pollute the environment during use. After being discarded, Pullulan Capsules can be quickly decomposed by microorganisms into harmless substances such as water and carbon dioxide, truly realizing green and environmentally friendly production and use.

The film-forming properties of Pullulan Capsules do have many unique features. This capsule shell made of pullulan not only has mechanical strength, moisture control ability and permeability, but also has good environmental performance. These advantages make Pullulan Capsules have broad application prospects in the fields of medicine, food, etc.
