film coating problems
- When it is not accurate in one of the components of the paint, whether from liquids or powders that are applied, it leads to the emergence of many problems.
- These problems appear in the effectiveness of the tablets and their marketing, as the patient does not accept any error in the drug form, and we do not forget that there are competitors and defamers who want to get rid of us in the market.
- Therefore, you must be careful and accurate in all steps when carrying out the tasks as much as possible, in order for the patch to be in the best condition and give the best impression.
The most important of these problems:
- Peeling occurs in the coating of the tablet, and if one part falls and the other part is exposed, it follows it and peels off a larger part due to the friction of the tablet with each other during coating, or that the components have a fault.
- The tablet stuck to each other because when the tablet was sprayed with paint, it was not placed correctly, and the percentage of moisture due to the liquid was more than correct.
- The tablet stuck to each other because when the tablet was sprayed with paint, it was not placed correctly, and the percentage of moisture due to the liquid was more than correct.
- Sometimes a convergence occurs, where part of the cover breaks and sticks to the other tablet, then they merge and become a deformed shape, in addition to the problem of color inconsistency on the tablets, all of them are in the correct form, so spotting occurs and the color concentrations begin to differ from one place to another.
Dyes:
