Abstract
A low coefficient of friction (COF) packaging film is disclosed. The low COF packaging film includes a first layer forming a first exterior surface of the low COF packaging film. The first layer includes a first polymer. The low COF packaging film further includes a second layer forming a second exterior surface of the low COF packaging film. The second layer includes a heat sealable polymer blend. The first layer is connected to the second layer. The first exterior surface includes a surface area roughness (Sa) in a range of from 25 nanometers (nm) to 250 nm. The first exterior surface has a static COF to itself less than 0.40 and a kinetic COF to itself less than 0.40, according to ASTM D1894.
