Holland Colours discusses using PET packaging for milk products. Milk needs protection from light to prevent vitamin loss and off-flavors. PET packaging with white colorants like titanium dioxide and Holcomer provide high light protection for milk while allowing packaging in transparent PET bottles. Holcomer provides stronger protection than titanium dioxide alone at lower dosage levels, making PET milk packaging economically viable. Holland Colours' solutions have proven effective for packaging various types of milk products including UHT, flavored, and extended shelf life milk.

PET from conversion
• This presentation focuses on milk
• UHT milk is dominated by carton
• Fresh milk is served by plastic for
many years already
• High growth emerging market

5. Milk needs protection
Extended exposure to visible
light will initiate photoxidation of
riboflavins
Secondary degradation due to
auto oxidation of lipids (milk fats)
results in off-flavors and nutrient
losses, especially of vitamins
All this results in a specific ‘light
taste’
Most damage by visible light 320-520 nm. For
maximum protection it is also important to hold
light penetration between 500 and 700 nm to
less than 2%

10. Increased loading of TiO2
Standard white concentrates require
dosing levels up to 30%
At those dosing levels, packaging costs
are prohibitly expensive and the high
pigment concentrations negatively affect
the production process, appearance and
mechanical strength of the containe
