Gels were said to not be a critical defect. Is this also true for film used in a FFS application?
As in all applications, the size of the gel will determine if it poses a potential problem in its respective application. In form-fill-seal applications, large gels have the potential to cause the pocket to blow out in the forming process. Determining what gel size and in what package location is acceptable is done through testing and discussion with the film supplier.
