The present invention relates to a method for identifying a blend of nucleators with reduced haze in nucleated polyolefin material compared to blends of the same nucleators having different component weight ratios. The method comprises:

Method for identifying a blend of nucleators useful for preparing a nucleated polyolefin material

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:

Additive composition, method of blending same and a low haze polyolefin material and preparation thereof

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 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 and 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.
