Alpine Kicks Off K With Lots of Layers
21. October 2016
Layers are great with chocolate cake. And blown film too. Hosokawa Alpine ran what’s believed to be a show first: an 11-layer line producing nylon-based barrier film.
Over the past few K Shows most suppliers have stuck with five-layer structures. Back in 1998, Battenfeld Gloucester, now part of Davis-Standard, ran a seven-layer nylon-barrier blown film line at K. At K 2010, Reifenhauser ran a nine-layer line. The system Alpine fired up on Day One of K 2016 featured 11, grooved-feed 65-mm, 32:1 L:D water-cooled extruders and a 560-mm X Die, as well as a new version of its V air ring designed to maximize output.
It was equipped with a film-stretching unit built into the nip. The line offers “infinite flexibility by allowing processors to bundle 11 equal layers” in the configuration of their choosing, says Dave Nunes, president of the company, whose U.S. operation, Hosokawa Alpine American, is based in Natick, Mass.
