Holland Colours: Colours of Value




.. where are the opportunities for growth
Global Market Segmentation and packaging mix

• From organic
growth and
conversion from
alternative materials




Our Contribution

Colour concentrates for milk based
beverages for monolayer PET for
selective light protection

Colour formulations compatible with
barrier systems used in alcoholic
beverages and juices.

Providing differentiation on the shelf
and protection for improved shelflife

… colours of value
for barrier for beer
Colours and additives can interact
with barrier systems
Need for compatible colour
Approach
Building an approved list of
OXN (OXygeN) -colours for
barrier materials
Several beer (and wine)
formulations commercialized



.. demands for beer
in PET
Improved barrier improvement
Commercial barrier systems on the market:
factors (O2,CO2) to ensure
required shelf life
O2 active scavenging
Block out light that reacts with
Metal (-assisted) oxidation certain hops, which could
damage the flavor
CO2 passive barrier Keep it cool…
Special polyamide resins/grades, Nanoclays

(In)organic coatings (C,SiOx)

Many combinations of above-mentioned
technologies



.. the right colours
for shelflife
… as example: monolayer PET bottle using Holland Colours OXygeN- colour
an OXN formulation
formulations are developed for
compatibility with barrier systems
Where interaction between
barrier and colours/additives is
possible
Building an approved list of
green and amber colours from
barrier material producers
Several amber and green
products commercialized

protection
Why use colour?
Block out light that reacts with
certain hops, which could damage
the flavor. Brown blocks best.
Improved logistics and storage in

packaging from organic growth

Success for beer in PET is about
challenging consumers
perception, as PET beer bottles
have potential to gain visibility on
retail shelves as a convenient
package with great visual appeal:

Summary

Growth opportunities in PET
packaging from organic growth
and conversion of glass and
other materials into PET

Colors are pivotal to success or
failure as colors catch shoppers
eye and convey information

Colouring solutions like OXygeN
colours and Holcomer add value
by providing protection for
Improved shelflife
