    摘要： The film is of the multilayered, biaxially oriented, polyolefin type and comprises titanium dioxide in a quantity of between 0.20 and 0.48% relative to the total weight of the film and at least one antifog additive in a quantity of between 0.2 and 1.2% relative to the total weight of the film. The titanium dioxide is present in the form of particles which have an average dimension of between 10 and 50 nm and are covered with a coating that opposes their agglomeration.
