Abstract (en)
[origin: WO0102107A1] The invention relates to a method which can be used to clean all types of flexible woven or unwoven, laminated or non-laminated thermoplastic films or thermoplastic material. The invention further relates to an alkaline cleaning composition. The inventive method is characterized in that it comprises at least one washing step in an alkaline medium in a bath in the presence of an alkaline washing composition comprising at least 5-8 % soda, 3-12 % carbonated soda, 10-28 % sodium perborate and 0-10 % surfactant(s), whereby said step is performed at a sufficiently low temperature in order to avoid any shrinkage or deformation of the above-mentioned film or material.
