Abstract
The invention provides a polyolefin pre-stretched packaging film comprising perforations arranged in a series of columns along a longitudinal direction of the film, wherein each adjacent column of said perforations is separated by a column without perforations along the longitudinal direction, and the perforations are staggered in a transverse direction across the film, wherein said film comprises an inherent cling surface on at least one of its surfaces; wherein the perforations cover at least 25% of the total surface area of the film, and the film has an inside/inside cling property of 5 to 22 gr, and a weight of no more than 13 g/m2.
Claims18
