Series 7D, Thermal Controlled Transport
Packaging for Parcel Delivery System Shipment, is described as covering only “basic
requirements: atmospheric conditioning,
vibration and shock testing,” writes
ISTA. In the preface of the procedure,
ISTA notes that “it can be used for
individual or comparative performance analysis of standard or insulated transport packages against
normally encountered conditions.”
Series 7D not only outlines testing procedures, but also specifies 12 thermal
profiles ranging from 24 to 72 hours for
both summer and winter. These profiles
can be used to determine the efficacy of
proposed packaging as well as offering
the ability to compare one package to
another. ISTA describes 7D profiles as
general simulations that are “not intended to represent the worst-case thermal
exposure in the small-parcel shipment
environment.”
As pharmaceutical and biotech
companies begin to outsource more
and more of their transportation
processes, it is imperative that these
comparative profiles more closely
meet the needs of today’s and tomorrow’s global transportation realities so
that vendor packaging can effectively
be evaluated and qualified.
THE REALITIES OF A GLOBAL INDUSTRY
With the completion of the first
rough draft of the Human Genome
Project (HGP) in 2000, the development of genetic and biologically based
products is increasing every year.
According to the annual report on the
global top 100 biotechnology companies by Euromoney Institutional
Investor PLC, the biotech industry
grew by more than 23% from 2005 to
2006 (Euromoney Institutional Investor
PLC, 2007, p. 26) up from 17% in the
prior year. Given the very nature of the
biotech industry, many of the products
generated by these companies are temperature sensitive. Consequently, the
next 5 to 10 years will also show dramatic increases in demand for all forms
of temperature-sensitive transportation
throughout the world.
PHARMA-BIO TRANSPORT | February 2008
International transport for finished
goods, clinical trials, active pharmaceutical ingredients, and raw materials will
increase correspondingly, creating
greater potential failure points in customs delays, missed or canceled flights,
and simple human error.
With the combination of increased
demand and a more global need,
enhancements to current testing standards for packaging qualifications are
needed in order to meet the new realities of the temperature-sensitive product packaging industry. The 72-hour
test (the upper-limit on the ISTA tests)
is no longer long enough, nor are the

existing Series 7D profiles based on
reality to allow for effective packaging
comparisons.
RECOMMENDATIONS
Recommendations for increasing the
difficulty of testing standards for disposable and reusable parcel packaging must
be considered. All international profiles
should be extended to 120 hours,
allowing for better time-failure control
as well as modifying the cycle limits
(specifically in time) to represent more
common transportation realities. The
following are a series of five tests that
would give a much closer comparative
capability. Each test should be run with
both minimum and maximum loads.
120-Hour Summer Profile. This
profile would represent warehouse storage at 25°C, a truck pick up time of 8
hours at 40°C, an international flight
time of 12 hours at 0°C, and another
truck delivery time of 8 hours at 40°C.
120-Hour Winter Profile. This
profile would represent warehouse
storage at 18°C, a truck pick up time
of 8 hours at - 10°C, an international
flight time of 12 hours at 0°C, and
another truck delivery time of 8
hours at - 10°C.
40°C Test-to-Failure Profile.
This test would show the impact on
the payload over extended periods of
time at the upper temperature control. It is designed to show how long
the package can protect the product
without intervention.
Minus 10°C Test to Failure Profile. This test would show the impact
on the payload over extended periods
of time at the lower temperature control. It is designed to show how long
the package can protect the product
without intervention.
120-Hour 25°C Constant Profile.
This test would determine the true
longevity of the packaging for a term
that would meet most needs.
These recommended testing profiles
are not intended to meet all extremes.
However, they should represent a much
more realistic pattern for chamber testing packaging products. Additionally,
the data derived from these tests can,
with robust packaging, allow for the
creation of mathematical models that
can be used for more-specific profiles
to determine packaging modifications
as required by extreme lane conditions.
Determining the future needs of the
cold-chain transportation industry
should be a high priority for all life science companies. With the increase in
biotech products expected to be
approved and the increase in global
sourcing, production, and trials, we
must plan now for what projects to be
an explosive growth rate over the next
5 to 10 years.
