HOW TO SOLVE BLOWN FILM PROBLEMS
Less extensible film — stiff overwrap from resin with a density of 0.935 g/cm3, or a high density, paper-like film — does not have the ability to stretch. The broad "smile" wrinkles appear if no attempt is made to increase the edge velocity. However, if the edge velocity is too great, edge wrinkles occur.

Blown film, cast film and lamination processes
Blown film is a major processing technique for producing a biaxial melt drawn film. This technique uses air pressure to produce a transverse direction (TD) draw and a higher speed haul off roll speed to provide a machine direction (MD) draw. Several billion pounds of polymer, mostly polyethylene, are processed annually by this technique [1].
