Pullulan Capsules are considered an ideal biodegradable material, mainly due to their unique physical, chemical properties and environmental characteristics. The following is a detailed analysis of why it is an ideal biodegradable material:

Film-forming and oxygen barrier properties: Pullulan Capsules are made of pullulan polysaccharide, which has film-forming and oxygen barrier properties. This material can effectively isolate oxygen and prevent the internal substances from deteriorating due to oxidation. Its oxygen barrier is 250 times that of other materials such as hydroxypropyl methylcellulose (HPMC) capsules and 9 times that of gelatin capsules. This feature enables Pullulan Capsules to provide a longer shelf life in applications such as medicines and food.
Biodegradability: As a biodegradable material, Pullulan Capsules can be decomposed into harmless substances such as water and carbon dioxide by microorganisms in the natural environment. This degradation process does not require additional energy consumption or the production of harmful substances, so it has a lower environmental impact. Compared with traditional plastic capsules, Pullulan Capsules can return to nature faster after being discarded, reducing pressure on the environment.
Safety: Pullulan Capsules do not contain animal-derived ingredients, avoiding the risks of animal-derived contamination and amino acid cross-linking reactions that may exist in gelatin capsules. In addition, as a natural polysaccharide, pullulan has good biocompatibility and biosafety, making the application of Pullulan Capsules in medical, food and other fields safer and more reliable.
Stability and drug release rate: Pullulan Capsules have stable physical and chemical properties and are not easily affected by the external environment. At the same time, its drug release rate is relatively stable, with small individual differences, which can ensure the continuous release and stable absorption of active ingredients in drugs or foods.
Sustainability: As a renewable resource, pullulan can be extracted from microorganisms through processes such as biofermentation. This sustainable production method enables Pullulan Capsules to reduce dependence on fossil resources and reduce negative impacts on the environment in production and application.
In summary, Pullulan Capsules is considered to be an ideal biodegradable material for its film-forming, oxygen barrier, biodegradability, safety, stability and sustainability. In the fields of medicine, food, cosmetics, etc., the application of Pullulan Capsules can not only improve the quality and safety of products, but also reduce the pressure on the environment and achieve sustainable development.
