Synthetic Paper for Tamper-Resistant RFID Tags, Labels
Hop-Syn XT–a white opaque, tear-resistant, monolayered synthetic
paper made from a combination of polypropylene and calcium carbonate–is
designed for printing tamper-resistant RFID tags, labels, and packaging.
Manufactured by high-speed calendering, Hop-Syn XT produces a uniform
gauge tolerance, high opacity, and an antistatic printing surface with
a microporous finish for quick drying, says the manufacturer, which
adds that the bright-white durable finish allows for higher-resolution
color printing and superb print definition. Ranging in gauge thickness
from .003 to .035, the company offers calendered synthetic paper with
a high temperature resistance (-60°F to 220°F) to distortion
and dimensional stability for perfing, die cutting, hot stamping, and
laminating. Hop-Syn XT can be applied to a variety of uses that require
tear and weather resistance, and is printable via numerous types of
printers.

Conductive Inks Reduce Cost of Antennae Printing
Parelec offers its Parmod VLT conductive inks and pastes, which enable
the printing of RFID antennae designs at high speed and low cost, says
the company. Parmod VLT is designed to combine the high conductivity
of bulk metal with the simplicity of printing. Direct printing of RFID
antennae with Parmod VLT enables the user to define a continuous in-line
dry chemistry manufacturing process to yield a low-cost RFID tag, says
the company. High-speed manufacturing enables the printing of antennae
and converting RFID tags directly into labels, eliminating the added
cost associated with constructing the tag on an interim substrate, according
to Paralec. In a continuous production line, graphics can be added as
an in-line production step. Because Parmod VLT uses a totally dry process,
users can eliminate the wastes and costs associated with subtractive
etching, states the company. Due to its higher conductivity versus polymer
thick film, less ink is required, thereby lowering materials costs.
Further, because of its high conductivity, Parmod VLT produces RFID
antennae with longer read distance than polymer thick film.
