Another way of producing layered structures has been brought to my attention and a summary of it can be found at (http://www.ces.clemson.edu/mmpl/concepts/Tutorial/tutorial.html), a Clemson...…]]> http://workflowPrepress.com/1382/using-%e2%80%9cchaotic-advection%e2%80%9d-for-micro-and-nanolayer-blending.php/feed 0 http://workflowPrepress.com/1384/making-nanolayers-another-way.php http://workflowPrepress.com/1384/making-nanolayers-another-way.php#comments Sun, 21 Dec 2008 00:00:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/19105-Making_nanolayers_another_way.php?rssid=20409
We’ve been discussing the formation of nanolayers using layer generators as described in several patents to Dow chemical and showing the impact of these layers on barrier and optical...…]]> http://workflowPrepress.com/1384/making-nanolayers-another-way.php/feed 0 http://workflowPrepress.com/1386/layer-breakup-in-micro-or-nanolayer-coextrusion.php http://workflowPrepress.com/1386/layer-breakup-in-micro-or-nanolayer-coextrusion.php#comments Thu, 18 Dec 2008 08:12:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/19110-Layer_breakup_in_micro_or_nanolayer_coextrusion.php?rssid=20409
Earlier I discussed the need for outer lubricating layers when forming micro or nanolayer coextrusions. This is discussed in US Patent 5,269,995 where the causes of the layer breakup are said to...…]]> http://workflowPrepress.com/1386/layer-breakup-in-micro-or-nanolayer-coextrusion.php/feed 0 http://workflowPrepress.com/1394/metallized-nylon-films.php http://workflowPrepress.com/1394/metallized-nylon-films.php#comments Wed, 26 Nov 2008 07:03:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/18982-Metallized_nylon_films.php?rssid=20409
I received this question by e-mail and thought it might be interesting to a wide range of readers. So, I will take a short break from nanolayer technology to put it here.

It would seem to me that as film layers get thinner and thinner when coextruding into nanolayer films there will be a point reached when the surface tensions of the liquid melts will exceed the...…]]> http://workflowPrepress.com/1395/surface-tension-effects-in-nanolayer-structures.php/feed 0 http://workflowPrepress.com/1396/nanolayer-coextrusion-impact-on-polymer-morphology.php http://workflowPrepress.com/1396/nanolayer-coextrusion-impact-on-polymer-morphology.php#comments Mon, 24 Nov 2008 15:25:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/19107-Nanolayer_coextrusion_impact_on_polymer_morphology.php?rssid=20409
While surfing the Web for nanolayer polymer applications, I came across several very interesting papers on PS/PP and PS/HDPE films with varying thickness polyolefin layers. The purpose of the...…]]> http://workflowPrepress.com/1396/nanolayer-coextrusion-impact-on-polymer-morphology.php/feed 0 http://workflowPrepress.com/1399/flat-die-nanolayers.php http://workflowPrepress.com/1399/flat-die-nanolayers.php#comments Tue, 18 Nov 2008 18:23:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/18976-Flat_die_nanolayers.php?rssid=20409
In a previous post I showed how to generate nanolayers using a rotating die and a feedblock which coextruded separate polymers side by side. This relied on laminar mixing behavior of polymers to...…]]> http://workflowPrepress.com/1399/flat-die-nanolayers.php/feed 0 http://workflowPrepress.com/1400/nano-layer-generation.php http://workflowPrepress.com/1400/nano-layer-generation.php#comments Sun, 16 Nov 2008 00:00:00 +0000 Converting - Substrate Secrets http://www.convertingmagazine.com/blog/Substrate_Secrets/18985-Nano_layer_generation.php?rssid=20409
Early nanolayer films were produced on blown-film lines and made use of the laminar mixing behavior of high-viscosity polymer melts. Because the viscosities are so high, the flows never become...…]]> http://workflowPrepress.com/1400/nano-layer-generation.php/feed 0
