Wrinkle reduction assembly

A method for reducing wrinkles in a film comprising:

• a) providing
• i) a first pair of cylindrical rollers comprising
• (a) a first roller and
• (b) a second roller,
• the first and second roller each in parallel juxtaposed relation to each other, and each having a substantially smooth surface;
• and
• ii) a second pair of cylindrical rollers comprising
• (a) a third roller and
• (b) a fourth roller,
• the third and fourth roller each in parallel juxtaposed relation to each other, and at least one of the third and fourth roller having a chevron pattern disposed on the surface thereof;
• wherein the first pair of cylindrical rollers is adjacent to and spaced apart from the second pair of cylindrical rollers;
• and
• b) advancing the tubular film such that the film passes first between and in contact with the first roller and the second roller;
• and then between and in contact with the third roller and the fourth roller.
