ABSTRACT:
A vinylidene chloride copolymer film having excellent bubble stability in an inflation-stretching process and excellent cold resistance is prepared by inflation-stretching a tubular amorphous substance obtained by melt-extruding and quenching a composition comprising vinylidene chloride copolymer, a miscible type elastomer (A component) and a particle dispersion type elastomer (B component) in a range surrounded by the lines (a), (b), (c) and (d) ##EQU1## WHEREIN A WEIGHT PERCENT OF THE B component to total elastomers is plotted on X axis (abscissa) and a weight percent of total content of the A component and the B component to total components is plotted on Y axis (ordinate).
