A film for packaging a product that has a pharmaceutical active agent includes a product-contacting sealing layer. The product contacting layer includes at least 90 wt. % of an ethylene norbornene copolymer having a glass transition temperature in a range from 50° C. to 110° C. The pharmaceutical active agent comprises a Hansen Solubility Parameter for the product-contacting sealing layer of 0.5 or greater.

A film for packaging a product that has a pharmaceutical active agent includes a product-contacting sealing layer. The product contacting layer includes at least 90 wt. % of an ethylene norbornene copolymer having a glass transition temperature in a range from 50&#xb0; C. to 110&#xb0; C. The pharmaceutical active agent comprises a Hansen Solubility Parameter for the product-contacting sealing layer of 0.5 or greater.

The present application describes a multilayer film having low water vapor permeability. The multilayer film of the present application is readily thermoformed and is, therefore, suitable for blister packaging sheets as well as for food packaging, medical barriers and device packaging, and other general purposes where low water vapor permeability is desired.
