A record for film blowing at a show: 11 layers.

Hosokawa Alpine (U.S. office in Natick, Mass.) ran what’s believed to be a trade-show first at October’s K 2016 fair in Dusseldorf: an 11-layer blown film line producing nylon-based barrier film. The line eclipsed the nine-layer line Reifenhauser operated at K 2010 and the seven-layer nylon-barrier line Battenfeld Gloucester (now part of Davis-Standard) ran at K 1998. Alpine's line at this year’s K featured 11 extremely quiet, 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.

The line was equipped with a film-stretching unit built into the nip. The design of the system offers “infinite flexibility by allowing processors to bundle 11 equal layers” in the configuration of their choosing, says Dave Nunes, president of Hosokawa Alpine American.

Throughout the exhibit, Alpine ran ExxonMobil’s Exceed XP8318 LLDPE along with barrier and tie-layer resins from DuPont, Ube, and Kuraray. Film was produced at a thickness of 50 microns (with a gauge variation of ±2%) and layflat width of 1800 mm. Output exceed 1200 lb/hr.

  • How to Optimize Adhesion in Hard-Soft Overmolding

     Over the past decade, soft-touch overmolding has radically changed the look, feel, and function of a broad range of consumer products.

  • PBT & PET Polyester: Part 2 The Performance Factor

    All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.

  • Melt Flow Rate Testing–Part 1

    Though often criticized, MFR is a very good gauge of the relative average molecular weight of the polymer. Since molecular weight (MW) is the driving force behind performance in polymers, it turns out to be a very useful number.
