This invention discloses a transparent standalone resin or masterbatch concentrate composition and manufacturing method of transforming commercial transparent grade base thermoplastics into anti-biofouling resins through extrusion or any similar hot melt mixing processes. The re-compound solids enable a number of product reforming processes, including but not limited to thermoforming, profile extrusion, injection molding, blow molding, blow filming, film casting, and spinning into articles of different shapes and geometries or overmolding on plastic substrates that can resist surface adsorption of microbes, mammalian cells, proteins, peptides, nucleic acids, steroids and other cellular constituents after solidification. The articles formed thereof additionally exhibit mechanical reinforcement and no leaching while retain the optical clarity of the base thermoplastics in the same product form as quantified in terms of the light transmittance and haze.

The present invention relates to an additive composition and a low haze polyolefin material which may be prepared using said additive composition. In particular, the polyolefin material is prepared from a polyolefin resin composition comprising one or more optical brighteners, bis-3,4-dimethylbenzylidene sorbitol and bis-p-ethylbenzylidene sorbitol at a certain weight ratio. In an aspect, the present invention relates to a method for forming a polyolefin material; said method comprising:
(i) preparing a polyolefin resin composition comprising polyolefin resin, one or more optical brighteners, bis-3,4-dimethylbenzylidene sorbitol and bis-p-ethylbenzylidene sorbitol, wherein the weight ratio of bis-3,4-dimethylbenzylidene sorbitol to bis-p-ethylbenzylidene sorbitol in the polyolefin resin composition is 45:55 to 25:75;
(ii) processing said polyolefin resin composition to form said polyolefin material.
