Influence of hydroxypropylmethylcellulose addition and homogenization conditions on properties and ageing of corn starch based films

► HPMC-corn starch films showed phase separation of polymers. ► Composite films had similar WVP to pure starch films and higher OP. ► Inhibition of the starch re-crystallization was reached when HPMC was incorporated to starch films in a 50:50 ratio. ► Composite films were more flexible.
