For rigid, semi conformable or full squeeze applications, film labels—
both white and clear—are becoming the choice to deliver outstanding
print graphics and visual effects that translate directly into more shelf
appeal for CPCs. From dynamic label shapes on complex curved
containers to a “no label” clear look with virtually invisible edge lines,
pressure sensitive film technology is adapting to deliver the kind of
visual impact that allows for differentiated products, increased brand
awareness and more share.
But exciting graphics isn’t the only aspect driving the move to pres-
sure sensitive films. Increasing demands for sustainability on the part
of consumers, brand owners and converters alike are moving pressure
sensitive film to razor thin dimensions. Thinner films translate into
less fossil fuel used for manufacturing, as well as less solid waste pro-
duced. And, when used with the newer adhesives available, they result
in significantly less bleed, thus reducing downtime associated with
oozing on press and on dispensing equipment.
Here’s what’s happening with film
label trends by market.
A premium label look dominates
the Wine & Spirits market. In
many cases, that means a clear
on clear film for labels designed
to create a clean, crisp, sophisti-
cated image that says, “Buy me,
I’m your brand.” When working
with clear labels and bottles, it’s
important the label plays a role
in covering surface irregularities.
Matching conformable film labels
with the proper adhesive to alle-
viate visible seaming or bubbles
can easily do this task.
The label is key in HPC. HPC brands are launching special edition
packaging with thin holographic films to showcase the uniqueness
of their product and draw attention at the shelf. But appearance isn’t
everything—label functionality is increasingly important. With some
brands, the use of less expensive, full squeeze containers results in
more irregular surfaces and the need for conformable films to provide
greater flexibility and more adhesive wet out.
As life gets busier, consumers crave convenience, particularly in the
Food market. On the go lifestyles are driving single servers and indi-
vidually wrapped packaging, while health conscious consumers are
looking for portion control, calorie sensitive servings and restricted
diet offerings like gluten and lactose free foods. As a result of this
growth in personalized packaging, pressure sensitive reclosure use is
skyrocketing, up 8 percent to 10 percent globally. Pressure sensitive
reclosures are available in a number of seal strengths and levels of tack
that are durable, efficient and flexible.
With the rise in counterfeiting, diversion and other forms of intellec-
tual property infringement, label security products are increasingly
critical for the protection of consumers and brand value. Label and
packaging security products create levels of anti tamper and anti
counterfeit solutions that reinforce product quality and assure authen-
ticity. Overt solutions include two dimensional holograms, clear tear
and tamper evident films, as well as laminated in security threads.
Additional covert solutions include infrared taggants and UV micro-
fibers and printing. Often brands are using multiple layers of these
security solutions to protect themselves in the global supply chain.
Pharmaceutical brands have begun to include RFID technology in
labels to increase traceability and compliance with regulations.
Dealing with Durables, like tire labeling, has traditionally been
a challenge, with problems (in this case) of staining from rubber
compound color migration. But new film materials are making those
problems a thing of the past. New polypropylene films not only pre-
vent staining, they eliminate curling for improved brand messaging
and retail appeal.
For chemical drum, container and barrel labeling, there’s an enhanced
range of films to meet the new Globally Harmonized System of Classi-
fication and Labeling of Chemicals (GHS) standards, as well as BS
5609 section 2 and 3 certifications.
In electronics, product traceability is vital in the assembly of printed
circuit boards (PCB). New, specially formulated polyimide labels
are ideal for tagging PCB and LED applications, with a highly heat
resistive topcoating to preserve label legibility even after the high
temperatures of soldering and chemical baths.
Flexible films have taken the world of Flexible Packaging by storm.
Flexible films possess good barrier properties on their own, but with
the help of coatings, film types and manufacturing processes, the
attributes and viability of the material are greatly enhanced.
• Traditionally, flexible packaging consists of multiple ply struc-
tures: typically PET, polyethylene, foil and a bonding layer fol-
lowed by a sealant. A trend has been to replace the foil layer with

GHS standards are met on chemical drum, container and barrel labels with
the help of an enhanced range of films.
Tag is commonly used for sock
bundling and is finding applications
on packaging comforters, pillows,
washcloths and other garments.
