Reduction in stress cracking of films

A method for reducing or preventing stress-cracking in a film product, comprising:

• (1) providing a package for storing an active-containing film product, said package comprising:
• (a) a top layer having an inner surface and an outer surface;
• and
• (b) a bottom layer having an inner surface and an outer surface,
• wherein said inner surface of said bottom layer comprises at least one polymeric material having at least one physical characteristic selected from the group consisting of:
• (i) a surface energy as measured by a water contact angle test of about 100 degrees or greater;
• and
• (ii) a surface RMS roughness of less than about 800 nm as measured by atomic force microscopy at a 100 micron square sample size level;
• wherein said polymeric material has a surface adhesivity level of less than about 0.25 lbf as measured by a peel force test using a load frame and packaging tape;
• and
• (2) packaging a film product comprising an active within said package;
• wherein stress-cracking of said film product is prevented or reduced when said film product is packaged in said package.
