| abstract |
ABSTRACT A stretched polyolefin film having a substantially uniform cellular structure and comprising a crystalline linear polyolefin, which film has the following characteristics:-(1) it comprises no more than 14% by volume of the film of closed cells; (2) it has an apparent density which is 90 to 20% of the density of the starting polyolefin composition; (3) it has a cell factor equal to or less than + 0.65, which factor may be zero or negative, (4) it contains 0 to 25% by weight based on the polyolefin of at least one additive selected from fillers and pigments; (5) it has a thickness up to 11 mils; (6) it comprises cells with dimensions that the average cell colume is not greater than 10-4c.c; and (7) it has been stretched in the plane of the film by an amount corresponding toa stretch ratio of at least 1.1 to 1 in the machine direction or the transverse direction or both. |
