Service offers laser etching advice to food packagers
Ampacet said it is responding to the increasing call for more secure
personal care, cosmetic, food and beverage, medical and pharmaceutical
packaging. Laser etching can be used to create indelible expiration
dates, serial numbers, bar codes and other marks. Processors can use
laser etching to help prevent counterfeiting and possible liability in
case such information switched.
The company's "LaserMark Solutions" service goes through the entire
marking process from formulation to testing to production. Ampacet will
select the best laser mark masterbatch for an application. The company
will often creates the masterbatch containing the other needed
additives and pigments.
"This step factors in all variables ranging from the properties of
the laser, such as its type, speed and power, to the nature of the
mark, the base resin and regulatory issues," Ampacet stated.
The service then tests various formulations to find the best one by
laser etching samples. As production starts, Ampacet works with the
manufacturer to oversee mark quality and consistency.
"In doing this, we define what our customer wants to achieve and
formulate to get the optimum bar code, alpha-numeric code or graphic,"
stated Tom Mickey, who heads the new service.
"We often tailor a masterbatch that brings a mica-based
laser-marking additive together with the other components called for in
a resin system. This new service rests on our longstanding experience
in laser etching, strong knowledge of how pigments and additives should
be combined, and our understanding of the packaging industry."
"Converters and packagers who want to use laser etching to make
their packaging more secure often need guidance in how to make it
work," stated Tom Mickey, who heads the new service. "We created
LaserMark Solutions to help them in this process. Our overall goal is
to enable end users to add laser marking additives to the plastics they
use without compromising the physical or aesthetic integrity of their
Manufacturers use laser marking to label products with more secure
and tamperproof marks. They also use the method because of certain
advantages compared to traditional ink jet and pad printing. For
instance, laser marking greatly reduces environmental concerns and
energy use by eliminating solvents and drying, Ampacet stated.
It also forms consistent and repeatable marks having greater
resolution, which means it can provide more data in less space than
other forms of printing. In addition, it allows marks to be changed
easily because it is computer controlled.
Ampacet offers custom colour, special effect, black, white and
specialty additive masterbatches for extrusion and molding plastic
