| Possible Causes |
Solutions |
|
Inadequate adhesion of the film coating
|
Select OPADRY II formulation for improved adhesion characteristics
|
|
Surface characteristics of the product being coated(e.g. hydrophobic substrate)
|
Modify core formulation to include more hydrophilic ingredients (where possible) or increase core porosity
|
|
Inappropriate design of logo(e.g. too detailed or too fine)
|
Select a different logo design (with increased area within the debossing and modified angles)
|
Insufficient plasticizer in film /
high internal stress
|
Reduce spray rate / increase drying rate
