VALUE SOLUTION Traditionally light blocking was achieved with use of multilayer HDPE and PET packaging. Traditionally, UHT liquid dairy products have been packaged in laminated paperboard cartons, pouches, or multilayer high density polyethylene (HDPE) and polyethylene terephthalate (PET) bottles. To increase the user friendly aspects of UHT dairy packaging, ColorMatrix Lactra SX Light Blocking Additive expands design freedom by allowing designers to use a single PET layer bottle to create the same visible light blocking as paperboard and multilayer HDPE and PET packaging.
