Starch based biofilms

Hello everyone, I am producing starch based biofilms, from wheat, corn and tapioca starch.
I am facing difficulties with tapioca starch and wheat starch the biofilm are too sticky?
Do you have any suggestion?

Thank you!

Hello Diana,

At which temperature you ae using tapioca starch because above 60 degree gelatinization will take place and it will become sticky.
