Abstract
The disclosure relates to a modifier composition for polyolefin, a polyolefin for packaging and a flexible packaging film. The disclosure relates to a modifier composition for polyolefin, including: (A) nano-silicon dioxide; (B) polyvinyl alcohol; (C) acrylic copolymer; and (D) Ethylene-Vinyl Acetate (EVA) copolymer. The disclosure also relates to a polyolefin for packaging, including: a polyolefin resin and a modifier composition of the polyolefin provided by the disclosure. The disclosure also relates to a flexible packaging film, of which at least a part is made of the polyolefin for packaging of the disclosure. The modifier composition of the disclosure can obviously improve the performance in the aspect of reducing residue of solvent in the polyolefin flexible packaging film.
