METHOD AND APPARATUS FOR AUTOMATIC EXTRUDATE LOADING AND ALIGNMENT

Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track. The extrudate handling system provides greater accuracy, reduced costs, and improved results.

Electric field “Z” direction alignment of nanoparticles in polymer solutions

A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.

Matte film and method of manufacture therefore
10710322 · 2020-07-14 · ·

A film structure having a matte film surface and method of manufacture thereof. The preferred embodiment of the present invention contemplates a blend of polyethylene homopolymer or copolymer resins, coupled with one or more platelet shaped (non-spherical) inorganic or organic fillers. The matte polyethylene film surface as prepared from these polymer/filler blends exhibits a low gloss matte surface for wide utility in laminated and non-laminated, food and non-food, packaging and non-packaging applications. A unique and heretofore uncontemplated technique of manufacture exploiting the phenomenon of die swell as enumerated herein is utilized during production to facilitate the reorientation of the fillers during the extrusion process to produce the matte surface effect.
