Abstract
A polyolefinic packaging film (1) for grease-containing foodstuffs with at least one blocking layer (3), a functional layer (5) and a filled layer (2, 4, 6). The packaging film (1) is stretched to produce a proportion of cavities, to adjust the overall density of the packaging film (1) for a recycling process to a value of less than 0.99 g/cm3.
