APPLETON, WISCONSIN—  Neenah, Inc. announced Friday it is closing its Appleton facility. The move is among operational changes the paper manufacturer is making, according to a news release.The company says it will lose $50 million in closure costs, but the move will improve its earnings by more than $7 million a year. The paper mill   currently employs about 100 people. Neenah Inc. expanded the Appleton Mill about five years ago. The facility is expected to be shut down by the end of September. The mill was originally built in 1865 as the Fox River Paper Company  and was once the largest mill in Wisconsin . The Appleton mill was eventually bought by Kimberly-Clark. Neenah Papers was spun off as a separate company in 2004.  Despite the rapid paper price increases this is the second major announcement of a mill closing. Just two weeks ago Storo-Enso announced the closing of it's largest mill in Finland.
