The Mechanical Properties of Hydroxypropylmethylcellulose Films Derived from Aqueous Systems Part 1: The Influence of Plasticisers Article in Drug Development and Industrial Pharmacy 7(6) Cellulose polymers (Fig.
) are made from dissolving include cellulose xanthate (a bright orange–colored solution formed by reaction of alkali cellulose with carbon disulfide, which is an intermediate product that on acidification forms regenerated cellulose such as cellophane, rayon, and meat casings), cellulose acetate (a plastic used in films, eyeglass frames, cigarette.

Hydroxypropyl methylcellulose (HPMC) belongs to the group of cellulose ethers in which hydroxyl groups have been substituted with one or more of the three hydroxyl groups present in the cellulose ring (Fig.
).HPMC is hydrophilic (water soluble), a biodegradable, and biocompatible polymer having a wide range of applications in drug delivery, dyes and paints, cosmetics, adhesives, coatings. Full Article. Nanocellulose in Thin Films, Coatings, and Plies for Packaging Applications: A Review.

The differences in linkages between the glucose units however are sufficiently great to cause great differences in properties. Pure cellulose is substantially insoluble in water, while starch can be readily dissolved in hot water.
