Oriented polymeric film coated with polyethyleneimine is disclosed, in which the polyethyleneimine is coated in-line, i. e., during the film manufacturing process for forming the polymeric film and before heat setting the film. In-line polyethyleneimine coated polymeric film, when used to make a laminate with other polymers such as polyethylene or ionomer type polymers, shows no signs of delamination between the polymeric film and the extrusion coated polymer after 2 hours in water at 121 DEG C at 0.1 N/mm2. In-line coating polyethyleneimine on the polymeric film can occur before any orientation of the polymeric film, during interdraw, with respect to biaxially oriented film, or after orienting the film, so long as the coating occurs before heat setting the film. The preferred polymeric film is polyethylene terephthalate.
