Milliken's ClearTint polymeric colourants for polypropylene (PP) aims to put some life into bottle caps. The ClearTint technology is showing how beverage caps, traditionally considered a commodity element, can become an added-value part of bottle aesthetics by replicating either beverage colour or brand colour in transparent PP as an enhancement of consumer appeal and brand image,the company said in a press release. One customer, Bormioli Rocco has created a range translucent screw closures for mineral water, soft drinks & other bottled beverages. Their design includes the use of ClearTint colourants. Bottle caps are normally made from aluminium or PP with solid pigments. In addition, PP provides mechanical & safety advantages by protecting the mouth of the bottle, absorbing any accidental bump & protecting the glass.
