“…Similar conclusions could be drawn from photographic evidence of sprayed HPMC films [4]. The potential for spray application conditions to influence film density has also been reported for free films generated from solutions of cellulose acetate in acetone [5]. Coated tablet film density will be dependent upon the degree of air entrapment within the film.…”

“…The resulting gel like solution of polymers and plasticizers were poured on siliconised glass mould and dried in an oven at 50°. The films were qualitatively characterized for their acceptability and stored in a polyethylene bag at room temperature separately78.…”

“…Weights were gradually added to the pan to increase the driving force till the film was broken. Tensile strength was determined by the formula, TS = (Break force/a.b)×(1+dL/L)711, where, L, a and b are length, width and thickness of the test strip respectively and dL is the elongation at break.…”

“…Longitudinal strips of the films were used, weight on the film was gradually increased so as to increase the pulling force until the film broke and the tensile strength was calculated. [10] Percentage elongation Longitudinal strips were cut out from the prepared medicated films. The flatness was determined at various points by using tensile strength apparatus.…”
