H
ow do I clean sealing jaws
that have a CPP coating?
W
e recommend using a
soft bristle brush or
Scotch-Brite pad (the less
abrasive, the better). One
of the unique things about
the CPP coating is that it
is impregnated in the base
metal. That means the coat-
ing won't chip, flake, or
peel off.

CPP: The answer for hardness.
Hardness is the key to extending the life-
cycle of your endseals. But hardness is
not an inherent property of any material.
As shown in the Rockwell "C" scale
below, our CPP coating substantially
exceeds the hardness of even heat-treat-
ed tool steel. In fact, our CPP coating is
one of the few substances on the planet
that test as high as RC 70.
CPP: The answer for corrosion
resistance.
Southwest Endseals' CPP coating offers
excellent corrosion resistance, especially
important in corrosive packaging applica-
tions. Our process also provides a surface
that will not flake, chip, or peel off. The
dense, non-porous coating prevents mold
and bacteria build-up and does not con-
taminate your packaged product.

y company spends thou-

alternative solution?
Y
es. Our customers are
able to eliminate the
cost and downtime associat-
ed with Teflon tape by choos-
ing our non-stick CPP coat-

coating offers superior

What qualities do you look for
in an endseal?
Most packagers seek two things above
all. The seal must release the film readily
and damage-free. And it must have great
durability and hardness, performing
extremely well even when subjected to
all sorts of stressful conditions. At stake
is nothing less than the efficiency and
profitability of your sealing operations.
At Southwest Endseals, we offer
the ultimate answer to both challenges.
The secret is in a proprietary technology
we call CPP, or "Composite Plating
Process."
How is CPP produced?
In a two-step process, we evenly deposit
a coating of polymer and dry lubricant
along the seal to a tolerance of less than
.0002 inches. Under intense heat, the
coating becomes part of the base metal
and will not chip or peel off. (See Figure
1.) Variations of this coating can be
applied to a variety of metals, including
steel, stainless steel, aluminum, brass,
and bronze.
CPP: The answer for anti-stick.
What gives our sealing jaws their "anti-
stick" powers? The CPP coating, which
has one of the lowest coefficient-of-fric-
tion ratios known. The coating complies
with USDA and FDA regulations and
works beautifully with both polyethylene
and polypropylene films. To top it off,
its anti-stick properties make clean-up
a breeze. And unlike Teflon coatings,
CPP coatings won't flake off.
Jim Dailey, maintenance manager of
Sara Lee Coffee & Tea Co. in Hayward,
California, has used Southwest Endseals
CPP technology for about five years. "It
works great - far better than anything
else we've tried. We just don't experi-
ence problems with CPP."
