2011 AIMCAL MARCH MANAGEMENT MEETING Speakers

has built a pressure-sensitive tape spooling
line utilizing Sahm winders. The
762mm (30-in.) line unwinds, slits, and
spools webs of various pressure-sensitive
tapes including foams. The rewind
section consists of 12 Sahm model 4 11
E spoolers, each capable of a maximum
package diameter of 400mm (15.75 in.),
tape width from 1.6 to 30mm (0.063 to
1.18 in.) and speeds to 450 m (1,450 feet)
per minute. Features include a score cut
slitting section capable of minimum slits
of 3 mm (0.12 in.), a shafted, floor pick-up
unwind and a provision to wind a liner
and/or exchange one liner for another.
The slitting station is adapted to accept
a drop-in shear or razor section as well.
Another section allows drop-in diecutting
capability if needed. For more
information, visit www.catbridge.com.
Pressure-sensitive tape spooling lines for tear strips,
films, and ribbons or custom configurations combine
web handling and slitting from Catbridge with spooling
from Sahm.

Interfilm Holdings Inc., Greenville,
South Carolina, parent company of
Brushfoil, Guilford, Connecticut, serves
as the North American distributor of
coated films from NanoPack Inc., Wayne,
Pennsylvania, including NanoSeal
barrier coatings for meat and cheese
packaging. The patent-pending oxygen
barrier from NanoPack can be used
for indirect food contact in accordance
with regulations administered under the
federal Food, Drug and Cosmetic Act by
the U.S. Food and Drug Administration,
Washington, D.C. “We began our
NanoSeal research in 2005, and introduced
our first commercial products
two years ago,” reports Howard Kravitz,
president and chief executive officer of
NanoPack. “What’s really noteworthy
about our latest achievement is that
we now provide a clear barrier coating
for meat and cheese packaging with
excellent barrier properties as well as
significant economic and environmental
advantages.” Current structures used
in meat and cheese packaging incorporate
polyvinylidene chloride (PVdC),
which is considered by some to be an
environmental negative. “The chlorine
given off by PVdC combines with
moisture in the environment and forms
hydrochloric acid, during the manufacture
of coated films and later in landfills.

Thus, the elimination of chlorine-bearing
PVdC reduces processing and disposal
concerns,” he explains. There also are
advantages when compared to barrier
structures using ethylene vinyl
alcohol (EVOH). “…while EVOH is also
a good barrier, more than 50 times of
it is required for comparable barrier,
at a higher cost,” according to Kravitz.
The NanoSeal technology also provides
flavor and aroma barriers. Applicable
markets include spices and coffee.
NanoPack’s technology already is being
used in ‘dry’ packaged products includ
ing nuts, crackers, cookies, confectionary,
and mixes. The environmental
benefits of NanoSeal are enhanced
by economics: less material is needed to
achieve better barrier than PVdC, EVOH
and polyvinyl alcohol.
In other news Interfilm has
installed a high-speed 80-inch Kampf
Conslit II slitter and received a Superior
rating in an audit by AIB International,
Manhattan, Kansas. The new slitter
continues Interfilm’s strategy of continu
ous improvement through investing in
equipment and technology upgrades.
This is the third Kampf slitter installed
in Interfilm plants in the past three
years. “The new equipment provides
higher throughput, better roll build, and
improved safety,” says Cindy Simpler,
Interfilm’s senior vice president of opera
tions.
On August 18, 2010, Interfilm’s
Rancho Cucamonga facility was
audited based on the Consolidated
Standards for Food Contact Packaging
Facilities established by AIB
International, Manhattan, Kansas. The
audit was conducted by Louis Stratford,
regional director for AIB International,
and resulted in score of 920 out of a possible
1000 points and a Superior rating.
AIB International audits evaluate the
entire production process from receipt of
raw materials through shipment of finished
goods. Interfilm’s Greenville, South
Carolina, facility received a Superior
rating in July 2010. Interfilm’s other two
facilities, North Aurora, Illinois, and
Glastonbury, Connecticut, are scheduled
to complete the audit process before the
end of 2010.
Interfilm and The Dow Chemical
Co., Midland, Michigan, are improving
the sustainability of oriented polystyrene
window envelope films with the
purchase of renewable energy credits
(RECs). The RECs offset the conventional
energy consumed in the production of
ProciteTM Window Envelope Films at
Dow’s plant in Hebron, Ohio. Dow and
Interfilm estimate that the RECs offset
energy consumption equivalent to the
electrical power used by 725 U.S. homes
for one year. The RECs are certified
through a third party, and comply with
regulations and audit processes set
by the U.S. Environmental Protection
Agency, Washington, D.C. Purchasing
RECs is an immediate, cost-effective
way to help reduce the environmental
impact of conventional electricity generation.
For every REC purchased, one
megawatt-hour of renewable electricity
is generated and delivered to the power
grid. Procite films combines clarity, readability,
and stiffness. Interfilm customers
may include a “Certified Wind Power”
logo on their window envelope products.

A Website presentation by The
Montalvo Corp., Gorham, Maine,
explains how the top and bottom
unwind stands on a Goss Urbanite Press
in Greenfield, Massachusetts, were economically
upgraded. The new assembly
relies on Montalvo’s closed-loop tension
control system with its S-3100ce digital
tension controller, an MPC4 I/P converter,
an MAF3 air filter, plus T-Series
load cell, V-series brake, and SKL safety
chuck. Prior to the upgrade, the unwind
stand used manual clamp brakes and
spring-loaded dancers. The upgrade
enhances operator safety, and enables
tool-free brake pad replacement, consistent,
constant, precise closed-loop digital
web tension control, and automatic
maintenance of selected tension set
points. For more information, visit www.

A presentation on the Montalvo
Website explains how to inexpensively
upgrade Mark Andy 4120 presses for
better productivity and reduced downtime
and waste. The key is controlling
minimal tension on extensible materials
from the full roll down to the core. If
significant unwind friction and torque
are occurring, the original brakes are
replaced with Montalvo C-Series dual
disc brakes. Benefits to Mark Andy press
users include the ability to compete with
