Blown Film

The blown film process, used to produce polyolefin-based film, is the most widely used conversion technique for film applications. Originally, mono-layer dies were used, but it is now very common for blown film to be produced from multi-layer dies, depending upon the final requirements of the film.

LyondellBasell customers can select from a large range of materials used in either mono-layer or multi-layer co-extruded structures. Grade choice depends upon the customer’s final application requirements. We offer a range of low density, linear low density, and high density polyethylene products with different melt indexes, densities and additive packages as well as polypropylene under a variety of trade names.
