4. PTR Perspective |
Packaging value chain approach
Blend science with solutions in
the value chain for a
sustainable competitive edge
IUFoST 4Claire Sand, PTR

5. PTR Perspective |
Packaging can change lives
Packaging can be sustainable, affordable and convenient
Packaging can enable affordable healthy food choices
Packaging needs to leapfrog technically and in the value chain
IUFoST 5Claire Sand, PTR

6. PTR Perspective |
We can do better
IUFoST Claire Sand, PTR 6

7. PTR Perspective |
We need to get unstuck
• Delivering sustainable packaging and protecting food to
avoid food waste is a balancing act that was a bit askew
and is recalibrating with much promise
• In the past, new packaging materials and lightweighting
were used as “drop-in” solutions so that the same processes
– manufacturing, distribution, retail, consumer use and
package disposal – were used with minimal disruption
• This approach severely limited solutions including packaging
materials
• Now, unsurprisingly, sustainability and food waste goals are
not attainable with these same solutions.
• Disruption and agility in the value chain are needed to
both enable the use of more sustainable packaging and
decrease food waste significantly
IUFoST 7Claire Sand, PTR

8. PTR Perspective |
There is hope
• Meaningful increases in sustainable
packaging and decreases in food waste are
attainable by reconsidering the value
chain processes that define how food goes
from farm to fork
• Value chain agility allows sustainable
packaging goals and reductions in food
waste to be achieved
• This disruption creates new opportunities
to use more sustainable packaging
materials/systems to and achieve food
waste goals

9. PTR Perspective |
There is alignment

While not viable in the past, sustainable packaging that
reduces food waste is in harmony with:

12. DESIGN
-FOR THE ENTIRE VALUE CHAIN
• Post-consumer value can be added to packaging through packaging
that is clearly recycle-ready by consumers and recyclers
• Separate needs

• SINGLE POLYMER COMPOSITE STRUCTURE WITH NAN

14. How it Works
Opportunity
• Consumer – intuitively or visually –
separable packaging
• Redesign packaging to allow
mechanical and structural support to be
separated from barriers
• Functional layers do not need to be tied
together to be functional
• Cost effective use of materials allows
for thicker separable layers of fully
recyclable polymers (PET sheet)
vs. thin layers of aluminum foil that
cannot be separated from base stock
• Enable benefits from consumer
recycling direction

RECYCLABLE
POLYMERS
PET - viable chemical recycling methods include:
• Energy intensive hydrolysis (using bases, acids and water) in which thermophilic
hydrolase actively degrades polyesters containing aromatic constituents
• Alcoholysis (using alcohols)
• Glycolysis (using glycols)
• Aminolysis (using amines) via aminolysis to poly (aryl ether sulfone-amide) results in a
new value-added polymeric material
Polyethylenes - viable chemical recycling methods includes:
• Chemical recycling via cross alkane metathesis (CAM) processing converts PE and other
polyolefins into liquid fuels such as diesel and waxes

16. How it Works
Opportunity
• Polymers easily separated
and recycled through the use of low
cost non-covalent interactions of
reversible adhesives
• Supramolecular reversible adhesives
such as PVP/PEG-400 produced by 0f
poly(N-vinyl pyrrolidone) (PVP) and
PEG-400 which serves as a
• Difunctional supramolecular cross-linker
that bridges the carbonyl groups of PVP
chains via hydrogen bonding
• Replace existing adhesive within
laminates

18. How it Works Opportunity
Impediments
• Embedded within film solutions to
attain high barrier films
• To reduce enable agglomeration and
settling of nanocomposites, multiple
setup processing and additives have
been employed and this has
increased cost and limits level of
nanocomposites
• This new process allows for ~25% by
volume of nanocomposites
• And, allows for a platform polymer
with variable permeability as a
function of the nanocomposite
concentration as well as the use on
paper creating a rapidly separable 2-
component polymer-paper high
barrier structure
• Recyclable single layer high barrier films
• This also can be applied to improving the strength of
hydrogels and thin films
• Volumes to drive production
• Cost vs. multilayer films
• Facilitate recycling of films or separation from
paperboard

Design
• Post-consumer value can be added to packaging through packaging that is clearly
recycle-ready by consumers and recyclers
• Technologies are not complex but require value chain management and innovation
• Design solutions offer IP opportunities in design
• Switch from current converting processes to more high-tech film forming processes
• Materials represent single layer construction for rapid recycling by consumers and
