18. EVAL TM FOR UHT MILK & ITS BENEFITS

19. BENEFITS OF UHT MILK IN FLEXIBLE POUCH
UHT MILK TYPICALLY HAS SHELF LIFE OF 3- 4
MONTHS EVEN IN ABSENCE OF COLD CHAIN
LONGER SHELF LIFE WITHOUT COLD CHAIN
MAKES NEW DISTRIBUTION CHANNELS
POSSIBLE
THIS IS HUGE ADVANTAGE AS COMPARED TO
TRADITIONAL PASTEURIZED MILK WHERE
MAXIMUM SELF LIFE POSSIBLE IS ONLY
ABOUT A WEEK AND THAT TOO IN PRESENCE
OF COLD CHAIN

20. BENEFITS OF UHT POUCH WITH EVAL
6 grams IS THE WEIGHT OF A 1 LITER
POUCH USING EVAL™EVOH BARRIER
LESS PRODUCT WASTE AS DESIGN
FLEXIBILITY POSSIBILE WITH EVOH
BASED MULTILAYER POUCH
BARRIER POUCH IS ALL PLASTIC BASED
HENCE TOTALLY RECYCLABLE
NO NEED FOR COLD CHAIN TO
MAINTAIN 100 % STERILITY IN THE
PRODUCT

21. BENEFITS OF UHT POUCH WITH EVAL
A FEW MICRONS OF EVAL ™ARE
SUFFICIENT TO PROVIDE THE DESIRED
AND FUNCTIONAL BARRIER OF UHT
MILK POUCH
SPOILAGE OF THE PRODUCT IS AVOIDED
AND ALSO PROTECTION TO VALUABLE
VITAMIN CONTENT
EVAL ™ACTS AS FLAVOUR BARRIER AS
WELLAS WELLAS KEEPING THE
OUTSIDE ODOUR AWAY
BESIDES MILK OTHER PRODUCTS
PACKED ARE FLAVOURED MILK , LASSI ,
