AIMCAL Fall Technical Conference
October 2008
Edward Cohen
The AIMCAL Fall Technical Meeting was help in October in Myrtle Beach,
NC. It provided a forum for the exchange of Information between
technical personnel in the web coating Industry. Technical papers were
presented in four sessions as follows:
• Environmental Responsiveness
• Web Coating & Laminating
• Vacuum Web Coating
• EmergingT echnologies
• Advances in Web Coating Technology
In addition there were table to exhibits, which also provide an
opportunity for additional technical discussions.
I found all of the presentations were useful and relevant to the technology of importance
to the Converting Industry. While the Coating process is sold, there is
still a a lrge amont of new technology that is being developed.
Wide ranges of topics were discussed, energy concerns, coating methods, slitting,
barrier layers, Coating hardware etc.
The following are the titles and a summary of some of the key
presentation. Details of the papers and contact information can be
found in the Conference Proceedings available from AIMCAL.
A Paradigm Shift In Knife Holder Slitting Technology
David Rumson
Sigmala, USA
Conventional slitting systems, consisting of mechanically
mounted and pneumatically activated knife holders (Mech/Pneu) have been
in existence for approximately 60 years. Although shear knife holder
and positioning systems have advanced during this time, there are some
basic operating requirements that remain limited in efficiency and
usefulness relative to today’s computer controlling capabilities. This
paper will present a basic overview of the physical operating
differences of Mech/Pneu holders and Servo Motor-Computer Controlled
holders (Serv/Com).
Application Of Surface Analysis For Root Cause Failure Analysis
David Cole
Evans Analytical Group
X-ray Photoelectron Spectroscopy (XPS) and Time-of-Flight Secondary
Ion Mass Spectrometry (TOF-SIMS) are valuable analytical techniques in
determining the rooot cause of failure in multilayer films.
Breaking Thru A Paradigm:New Technology For Coating And Laminating
Mike Budai
TW Dynatec
The purpose of this presentation is to break thru a paradigm in
laminating nonwovens, textiles, and composites. This paper will present is to
introduce the latest technologies in coating and laminating utilizing
hot melt polymers.
Reducing Changeover Time on a Coating Line,
Larry Gogolin
Gogolin & Associates
This paper will cover the steps to consider in establishing a reduction in the changeover time. It will look at planning, data collection, analysis and what to do with this
information.
Optimizing Mix Performance”
Ken McCarthy
This paper presents a discussion of mixing time and its importance to
coating operations.
Stay Ahead of Static Problems in Film Conveyance
Kelly Robinson,
Electrostatic Answers LLC
Demands for static control in film conveyance are increasing because
products are more complex and sensitive to static discharges. Four keys
to staying ahead of static problems in web conveyance are presented T
he implementation of these four recommendations for a typical coating
operation is presented.
Primerless Heat Seal Coatings for Film Substrates
Virginia Cushing &Robin Cooper
Michelman
This paper presents a single pass, aqueous heat seal coating which
exhibits excellent hot tack and a wider operating window as compared to
conventional heat seal coatings and common extruded sealants.
Increasing Energy Efficiency in the Web Coating Process
Edward Cohen, Dan Bemi Megtec
This paper focuses on reducing energy consumption, by modifying the
overall coating process and to utilizie renewable resources in their
production in order to remain competitive in this climate of rising
energy costs.
Intelligent Process Cooling: Saving Money, Protecting the
Environment
& Curing Process Headaches
Steven Petrakis
Frigel
Process cooling with ambient air, closed loop cooling systems can save
up to 25% on energy and water consumption in addition to eliminating chemical
evaporation and the disposal of contaminated waste water.
Nanoparticulate Barrier Films and Gas Permeation Measurement Techniques
for Thin Film Solar and Display Applications
Senthil Ramadas*, Shwe Zin Ma, Mark Auch, Chua Soo Jin
Institute of Materials Research and Engineering.
This paper presents innovative approach to resolving the ‘pore effect’
by literally plugging the defects in the barrier oxide films using
nanoparticles. The nanoparticles used in the barrier stack have a dual
function – not only sealing the defects but also reacts with moisture
and oxygen. The result is an achievement of moisture barrier
performance of better than 10-6g/m2/day that surpasses the ideal
requirements needed for flexible applications,
