Polymer physical gels have been used in numerous practical applications within food processing, chemical, cosmetics, pharmaceutical and agricultural industries. They may be obtained on the bases of synthetic and natural polymers. Natural polymers are easily biodegradable, hence their more extensive usage within the areas where synthetic polymers have been applied so far.

In line with the increasing demand for sustainable packaging materials, this contribution aimed to investigate the film-forming properties of hydroxypropyl methylcellulose (HPMC) to correlate its chemical structure with film properties. The roles played by substitution degree (SD) and molecular weight (Mw) on the mechanical and water barrier properties of HPMC films were elucidated.
