Convection Hot Air • Infrared Radiant • Steam

Shrink sleeve packaging is more than 50 years old –
but it took PDC shrink tunnels to give shrink sleeves
the precision, speed and energy efficiency demanded by global food, pharmaceutical and dairy companies.

PDC shrink tunnels are engineered for the
application of heat shrinkable sleeve labels and
tamper evident banding.  They produce highly
consistent film shrink for best-possible product appearance, and lowest-possible energy use.

PDC shrink tunnels are manufactured from
dual-wall, heavy gauge stainless steel. This
construction specification lets hot air circulate
for greatest efficiency, while protecting operators
from high heat. 

Shrink tunnels manufactured by PDC include infrared, hot air convection, steam, and combinations of these types. PDC shrink tunnels can be sequenced, and
pre- and post-shrink modules can be configured for
special applications.

Our newest shrink tunnel is our KST 80-A-712 with steam venting package. This adjustable steam tunnel offers virtually universal shrink performance.

Our ability to customize a system to your requirements is what makes PDC shrink tunnels
an exceptional choice – and an exceptional value!  As with all PDC systems, we can offer
recommendations based on your container geometry, dimensions, substrate and temperature,
as well as the line speed whether containers are empty filled, and other variables.

We also have decades of experience working with the performance characteristics of all
shrink materials, so if you’re deciding between PVC, PETG, OPS and PLA, PDC material
specialists can provide objective insights that are applicable to your application.

NEW! Triple Zone Steam Shrink Tunnel

The KSA-70-712 is a high quality steam tunnel that incorporates many of the
engineering features which have distinguished PDC's larger capacity tunnels
and labeling systems.  It is ideal for applications that demand precise label registration
and shape conformance.  It is also an excellent option for packages involving
contents that are flammable or under pressure.

The KSA-70-712 is a compact, 70" long system that precisely focuses steam onto
specific points of the shrink-sleeved packages. The tunnel has symmetrical steam
distribution tubes on each side, and each pair of tubes is externally adjustable for
steam volume, flow and rotary nozzle position. Adjustments can be made "in real time,"
without wasting time – and energy – waiting for the tunnel to cool down.

A thermostatically controlled steam chamber, available as an option, generates the
most energy-efficient steam system possible. Unlike straight pressure systems,
which waste energy by pumping large volumes of steam into the tunnel without
electronic regulation, PDC's unique control system uses only the steam required to
maintain chamber temperatures and provide optimal shrink quality.   

Opening dimensions for the KSA-70 are 12" high X 7" wide. The KSA-70-712 provides
precise label registration, distortion-free graphics, and exceptional conformance to the
container shape. The system virtually eliminates the risk of container distortion. 
PVC, PETG, OPS and PLA films, in gauges as thin as 40 microns, are all compatible. 

The KSA-70 can process up to 200 cpm, depending on container size and shape. 
Containers can be virtually any geometry, including round, oval and square, and can
be filled or empty. Where bottles are labeled empty, a heated shroud is available to
prevent condensate from dripping into empty containers. Other optional features
include an electronic temperature regulator, a powered steam venting manifold
with dampers, and a condensate diverter package. 

Several levels of steam filtering provide up to culinary grade steam,
while also removing impurities. PDC can also provide a range of steam boilers
optimally sized to customer requirements. 

The KSA-70 steam tunnel is an excellent choice for end-use packagers. It is ideal as
a stand-alone system, or as a supplemental "finishing zone" for a dual-zone tunnel. 
It is also highly efficient as a pre or post-shrink module.  The KSA-70 is equally
well-suited to contract packers who need a highly reliable and very economical
steam shrink tunnel.  

An adjustable manifold system provides highly efficient, reliable and low cost means of rapidly supplying steam directly to the heat shrinkable sleeves. Our steam shrink tunnels provide the most uniform and distortion-free results and are particularly well suited for full body shrink labels.
