Abstract
The present disclosure relates to a method for establishing the suitability for printing of a thermoplastic film for use in a packaging of absorbent hygienic articles, said thermoplastic film comprising at least 30% recycled polymer material. The method comprises scanning a sample of said film for Gel Spots, defining an Amount of Gel spots and a Relative Gel Spot Coverage area, and, determining that if the Amount of Gel Spots is less than or equal to a first threshold and the Relative Gel Spot Coverage Area is less than or equal to a second threshold, determining that said thermoplastic film is suitable for printing. The disclosure also relates to a method of forming a package from a thermoplastic film, and to a package comprising a thermoplastic film.
