Pharmaceutical Tablet Film Coatings | PharmaCentral
The polymer is the film former and the main component on the formulation. The ideal polymer is one capable of producing smooth, thin films that are reproducible under routine coating conditions. The range of materials that can be used as film formers is very wide and covers materials that may be natural, synthetic or semi-synthetic.
Film coating | SEPPIC
The film-coating formulation combines four key ingredients: A film-forming polymer, which provides the mechanical strength of the film. The most widely used polymers in non-functional film coating are cellulose derivatives such as hypromellose. Plasticizers, used to improve the flexibility of the film formed and prevent it from cracking or
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.
Understanding Tablet Coating Process | LFA Tablet Presses
Castor oil is primarily used as a base for organic solvent solutions; on the other hand, PEG and PG are commonly used for aqueous coating. External plasticizers must be soluble in the solvent that is used to dissolve the plasticizer and film. The film former and the plasticizer must however achieve at least partial mutual solublity in the solvent.

- Can plasticizers be used in coating formulations?
- For natural products or hard polymers of poor processing, the option is the external use of plasticizers in the coating formulations. Plasticizers interact physically with the polymer binder molecule, without a chemical reaction and form a homogeneous system.
- What are plasticizers used for?
- Plasticizers are additives that increase the plasticity or fluidity of a material. Coating formulations based on physically drying binders such as nitrocellulose, require external plasticizers for optimal film formation. They are used to control the film formation process of coatings based on physically drying film-forming materials.
- Which plasticizers are used in coatings?
- Commonly used plasticizers in coatings are: DINCH (dicarboxylate) and more. Plasticizers may be solvents or non-solvents to the binder. For example, NC is soluble in plasticizers such as di-butyl phthalate (DBP), di-iso-octyl phthalate (DIOP), di-octyl phthalate (DOP) & tricresyl phosphate.
- What is a film former used for?
- Film formers are widely used in hair and skin-care products like moisturizers. When applied on the hair or skin, they form a supple, cohesive, and continuous layer. This layer/film has water-binding properties that leave a silky and smooth effect on the skin.
- What are external plasticizers?
- Main external plasticizers are low molecular weight materials, demonstrating fast interaction with the polymer chain. However, in specific cases also, polymers are used as plasticizing material. For instance, NC lacquers may be modified using synthetic resins such as alkyd resins to control flexibility and reduce brittleness.
- Is ATBC a safe plasticizer?
- ATBC is considered as a safe, low toxicity, alternative plasticizer demonstrating improved biodegradability and biochemical properties, as compared to phthalates. ATBC is widely used now for NC coatings as well as NC food packaging inks & packaging of medical products.
