  • High clarity polyolefin multilayer blown coextruded film
    Patent number: 6368545
    Abstract: At least two techniques can be used separately or together to achieve higher clarity in multilayer blown coextruded films. In a first technique, the core layer is extruded at a higher temperature than the skin layer or layers. In the second technique, the core layer has a higher density than the skin layer or layers. Combinations of these techniques are also contemplated. Either one or both techniques may be used to a sufficient degree to improve clarity (generally lower haze).
