Maximum freedom of design for milk bottles Swiss injection moulding machine manufacturer Netstal presented its Prelactia packaging solution for liquid dairy products at Chinaplas. In addi- tion to fullling numerous technical functions, modern-day packaging also needs to be an attractive adver- tising media and purchasing incen- tive. Brand owners in the carbonated soft drinks seg- ment have long since exploited the broad freedom of design offered by PET bottles in an endeavour to stand out from the com- petition at the point of sale with increas- ingly unconventional bottle shapes. This phenomenon is less common in rela- tion to the lling of liquid dairy products due to the signicant limitations of conventional HDPE and carton milk packaging. “Prelactia PET preforms provide llers of liquid dairy products with new opportunities to distinguish themselves from the competition with customised bottle shapes,” explained Stefan Müller, Sales Director Asia at Netstal. Improved light barrier The double-layer structure of the patented barrier preform offers an economic benet compared to other packaging processes. During the rst step of the overmoulding pro- cess, a 1mm-thick, inner grey layer is injected. The dark colour effec- tively creates a light barrier. “A good comparison would be with early milk bottles made of dark-brown coloured glass, Prelactia blocks out virtually 100% of the visible light spectrum. As a result, the bottles are particu- larly well-suited for milk products with South Hall · S21085 German Technology Barrier packaging for liquid dairy products The PET-Line 2C is a high-performance injection moulding system for two-com- ponent preforms.
