MULTILAYER FILM OF A WALL OF A BAG HAVING SEAMS AND INTENDED FOR A BIOPHARMACEUTICAL PRODUCT

摘要

The invention relates to a single-layer contact film (8) intended, once secured to a multilayer functional film (9), for forming a final multilayer film (7) of a wall (2) of a bag (1); the bag (1) comprising seams (3) at least on said bag and intended for being filled with a biopharmaceutical product, made of a material selected so as to be suitable for: being used in the formation of a final multilayer film (7) of a wall of a bag; being in contact with the biopharmaceutical product, without damaging the film (7) and the biopharmaceutical product; being sealable on the bag, having a thickness that is less than the thickness of a single contact layer of a final multilayer film (7) of a wall of a bag suitable for the formation of seams of the single contact layer on said layer, one of the surfaces of which has the purpose of providing a securing interface with a first securing interface of the multilayer functional film (9), the other of the surfaces having the ultimate purpose of forming the contact surface between the final multilayer film and the biopharmaceutical product.
