Abstract
The present invention relates to a film having a liquid at least partially absorbed therein, wherein the liquid has been applied to a surface of the film and prior to application of the liquid to the surface, the surface has been subjected to a surface activation treatment such that the surface has a surface energy of at least about 50 dynes.

A nylon film consisting of (a) one or more aliphatic primary diamine and one or more aliphatic dicarboxylic acid, (b) an omega-aminocarboxylic acid, (c) an omega-aminocarboxylic lactam, or (d) a mixture of two or three of (a), (b), and (c), and having a liquid at least partially absorbed therein, wherein the liquid has been applied to a surface of the nylon film and prior to application of the liquid to the surface, the surface has been surface activated such that the surface has a dyne level of at least about 50 dynes and the amount of liquid able to be absorbed by the nylon film after said surface activation is higher than the amount able to be absorbed before said activation wherein the film is in the form of a tubular casing, and the surface is a food contact surface.
A nylon film consisting of (a) one or more aliphatic primary diamine and one or more aliphatic dicarboxylic acid, (b) an omega-aminocarboxylic acid, (c) an omega-aminocarboxylic lactam, or (d) a mixture of two or three of (a), (b), and (c), and having a liquid at least partially absorbed therein, wherein the liquid has been applied to a surface of the nylon film and prior to application of the liquid to the surface, the surface has been surface activated by the application of energy such that the surface has a dyne level of at least about 50 dynes and the surface receives energy of a watt density of at least about 75 W-min/m2 and the amount of liquid able to be absorbed by the nylon film after said surface activation is higher than the amount able to be absorbed before said activation wherein the film is in the form of a tubular casing, and the surface is a food contact surface.
