Which polymer is used in film coated tablet?
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 breaking.
Which one is big advantage of a tablet?
1. They’re so light and portable. Whether you like getting work done or getting entertained on the go, tablets offer one clear advantage: they’re portable. Tablets are often about one third the weight of a standard laptop, so the physical strain of carrying a lightweight tablet is far less.
What are the 3 types of tablets?
There are different types of tablets:
- Chewable tablets dissolve and are absorbed rapidly in the stomach, offering a quick onset of action.
- Orally disintegrating tablets dissolve on the tongue.
- Sublingual tablets go under the tongue.
- Effervescent tablets are dissolved in liquid and then drunk.
What are the advantages of surface treatment?

What are tablet coatings made of?
Film coating
Some of the non-enteric coating polymers are Hydroxyproply methyl cellulose (HPMC), Methyl hydroxyethyl cellulose, Ethylcellulose, Povidone, etc, while the commonly used enteric coating polymers are Cellulose acetate phthalate, Acrylate polymers (Eudragit L& Eudragit S), HPMC phthalate, etc.
What is the difference between coated and uncoated tablets?
Tablets can be either coated with a sugar or film coating, or uncoated. Uncoated tablets are rougher, may be more difficult to swallow, and often leave a bad taste in the mouth when swallowed. A coated tablet generally goes down easier and with less aftertaste.
What is the thickness of powder coating?
The standard film thickness for a standard powder coating for optimum mechanicals is between 60 and 80 microns (~2-3 mils). Thickness measurements of powder can be taken before and after curing.
Why is powder coating good?
Powder coating provides better performance than wet paint—it is more resistant to chipping, scratching, and other wear because of the thermal bonding it undergoes during curing, and because it can be applied in much thicker layers.
How heat resistant is powder coating?
The most common powder coatings can withstand temperatures between ambient to 200°F, although most are on the lower end of the spectrum. These general powders will do the trick for most typical applications, but may be susceptible to significant color change and other issues once you start pushing that 200°F+ range.
