Netstal at the Drinktec Beverage
Technology show 2017 held in Munich,
presented two layers Prelactia light
barrier PET preforms for milk products
and drinks with higher shelf life. These
preforms consisted of a 1-mm inner layer
of gray PET, which is overmolded with a
1.4-mm white outer skin. This approach is
said to provide an improved light
barrier—blocking nearly 100% of visible
light—while cutting the use of expensive,
UV-blocking titanium dioxide white
pigment.”
