3: Why pullulan:

The reason that we choose pullulan is due to following factors:
1): Pullulan is more natural, involving no toxic chemicals, much less environment polluting in its production process
2): Pullulan possesses more potential for price reduction when produced in mass, because the fermentation technology used is widely used and very mature.
3): Pullulan film is 300 times stronger oxygen barrier than HPMC film, 9 times stronger than gelatin film
4): Pullulan is much more inert than gelatin or HPMC, so there is no interaction with products it intended to deliver.

4: How pullulan is made:
Commercially, Pullulan is from fermentation process. Aureobasidium pullulans grow on the carbohydrate substrate (sugar or starch. ThenAureobasidium pullulans is harvested. Followed by rupture the cell with either enzyme or physical force. Pullulan then is extracted using simple water extraction process. There are no environment damaging waste, or carcinogenic material used.
