Film Formers & Plasticizers for Tablet | Pullulan Applications
Pullulan is a natural polysaccharide excipient that possesses excellent transparent film–forming ability, moisture absorptivity, water solubility and adhesivity. It is also used as a coating agent for tablets, pills, granules and capsules. Ingredient (s): Pullulan Dosage Form: Tablet Category: Film Formers & Plasticizers
Film coating | SEPPIC
Seppic develops effective and easy-to-use film coating agents for medications and dietary supplements, thanks to its expertise in film coating, and in selecting compositions based on a tablet’s type and desired functionality. The tablet coating process The coating process results in the formation of a thin layer of polymer around the tablet.
Pharmaceutical Tablet Film Coatings | PharmaCentral
A pharmaceutical film coating is a polymer-based membrane applied onto solid dosage forms, such as tablets, capsules and granules, in order to impart certain desired attributes that are otherwise absent in the uncoated product.
Film forming agents
Featured film forming agents for solvent based systems. 1. EFKA PL 5381. Standard epoxy plasticizer which is extraction-resistant to many industrial agents. The migration resistance is comparable with polymeric plasticizers. 2. EFKA PL 5382. Epoxy plasticizer that improves whiteness and resistance to ageing with food contact range.
Tablet Coating Process: Film Coating
The process of film coating involves the deposition of a thin, but uniform polymer-based formulations onto the surface of solid dosage forms such as tablets, capsules, powders, granules, or pallets under conditions that permit: Balance between, and control of, the coating liquid delivery rate and drying process.
- What type of polymer is used to make a tablet?
- Polymers such as ethyl cellulose and altered acrylates are used. Tablets that are compressed are coated with sugar layer and may be colored or uncolored depending on the tablet’s purpose. The sugar coating is water-soluble making it easier to dissolve quickly
- What is a tablet coating?
- Coating Composition – the coating comprises the ingredients that have to be added to the surface of the tablet and the solvent used to act as the ingredient’s carrier. Tablet Surface Area – plays an important part in the uniform coating of the tablet. The total area for the unit decreases considerably depending on the size of the tablet.
- What is grossing & smoothing a tablet?
- The Grossing or smoothing step involves filling out and smoothing irregular features or areas of the tablet. After each filling step, the tablet is smoothed by polishing, refinishing the tablet so that a smooth and finished look is achieved. The process gradually also increases the size of the tablet to the required dimensions.
- What are the disadvantages of a tablet coating process?
- Once dipped in the solution, the tablets are then placed in a traditional coating pan to dry. The steps are repeated until the desired coating is achieved. Disadvantages for this process include the lack of versatility, low speed as well as low reliability compared with the spraying methods.
