Heat sealing property of self-supporting edible films based on corn starch and a functional polysaccharide, such as amylose (AM), methylcellulose (MC) or hydroxypropylmethylcellulose (HPMC) was evaluated. Films were prepared in the laboratory by casting and heat sealed at 85–166 °C by an impulse heat sealer. Irrespective of film composition, sealing temperature influenced the seal strength. Films sealed at temperature <143 °C showed peeling mode failure attributing to weak seal strength,...
