C. and that at least one central layer (3) contains polymers having softening temperatures of below approximately 70.degree. C. The non-PVC multi-layer film (1) is particularly suitable for the production of medical bags, in particular multi-chamber bags, as the materials of the individual layers (2-4) are selected in such a manner that the film is transparent and flexible, but in particular also heat-sterilizable, fusible and heat sealable. The film is moreover completely recyclable.
