Abstract
The invention relates to the use of a biaxially oriented polyolefin film as a label film. The inventive film consists of a base layer and at least one cover layer. Said cover layer contains as the main component a copolymer or terpolymer consisting of one alkene and unsaturated carboxylic acids or the esters thereof and low amounts of an additive. The cover layer is characterized by excellent and divers adhesion to various polymer materials from which containers are formed. It is no longer necessary to apply adhesives, primers, coatings etc. in a separate step after production of the film.
