ABSTRACT A radio frequency polyolefinic film containing an acid copolymer/quaternary amine mixture is disclosed. The film is permanently antistatic. The acid copolymer is a copolymer of (i) a major amount by mol % of an alpha-olefin of the formula RCH=CH2 wherein R is H or C1 to C20 alkyl, and (ii) a minor amount by mol % of an alpha,beta-ethylenically unsaturated carboxylic acid. The quaternary amine is of the formula [(R1)(R2)(R3)(R4)N]' [X]- wherein R1 is selected from H, aryl, or C1 to C50 alkyl optionally having one or more non-contiguous C=O or NHC=O or -S- or -O- in the carbon chain, or the same as R2; each of R2, R3, and R4 is the same or different and se- lected from H, from C1 to C18 alkyl optionally substituted with one or more OH, or from -(R5-O)a-H where a is an integer from 1 to 10 and R5 is ethylene or propylene; and X is an anion selected from chloride, bromide, iodide, fluoride, nitrate, fluoborate, phosphate, C1 to C8 alkyl phosphate, sulfate, C1 to C8 alkyl sulfate, formate, C1 to C20 alkyl or C6 to C24 alkaryl or aryl sulfonate, acetate, citrate, trifluoroacetate, propionate, tartrate or carbonate.
