摘要
Moisture and gas permeable ionomeric films are described. The films described herein are obtained from blends of ionomers with an organic acid salt in the amount of at least about 5 wt %, and have MVTR greater than films obtained from conventional ionomers. Particularly preferred are the potassium salts of stearic, oleic, isostearic, and isooleic acids. Films comprising a liquid-absorbent ionomer film layer and an impermeable layer are provided. The films are suitable for preparation of tubular casings and shrinkbags, in particular, casings for smoked foodstuffs.
