<p>PURPOSE:To provide a resin composition outstanding in mechanical properties and gas barrier nature under highly humid conditions and capable of giving drawn formed products of both good gas barrier nature and transparency comprising a low-melting polyamide resin and vinylidene chloride resin and specified proportion. CONSTITUTION:The objective resin composition comprising (A) >40wt.% but <=95wt.% (pref. 45-90wt.%) of a low-melting polyamide resin <=210 (pref. <=200, esp <=190) deg.C in crystal melting point and <=55 (pref. <=47) deg.C in glass transition temperature and (B) <60wt.% but >=5wt.% (pref. 10-55wt.%) of vinylidene chloride resin, pref. a copolymer from 65-98wt.% of vinylidene chloride and 2-35wt.% of a copolymerizable monomer (e.g., vinyl chloride). The other objective drawn formed product therefrom is such as to have at least one layer comprising the above-mentioned composition with the dispersed granules of the component B in the layer(s) assuming a long, flat shape in at least one draw direction and the flatness for the sectional area of the dispersed particles >=2.</p> |
