<p>Flexible, halogen free, high frequency sealable films fabricated from a blend of a copolyamide and a polyolefin having a carboxylic acid or carboxylic acid anhydride functionality have sufficient copolyamide to yield a DLF of at least 0.05 at a frequency of 27 megahertz and serve as effective substitutes for flexible polyvinyl chloride films. The films may be mono layer films or multi layer films, especially where the high frequency sealable films serve as outer or skin layers in multi layer films. Products made from such mono layer and multi layer films find utility in a number of applications, especially for medical device applications.</p> |
