The film forming solution (FFS) is stirred overnight and it is oven dried at 40°C.
Please give me suggestions to reduce the air bubble.
The aloevera gel preparation doesnot requires more water and 9% pva and addition with aloevera strirriring by magnetic beads will help and 12000rpm for 1 hr and hot air owen for drying

Hello, I suggest to place the prepared filmogenic solution under vacuum at room temperature for about 15 minutes (depending on the need, you can increase or decrease the time) before the casting and drying steps. You can do this step by using that vacuum oven. I hope my answer was useful.
