EVAL™ provides excellent oxygen barrier
Condition: 20C-65%RH(out)/65%RH(in)
Application of EVALTM
EVALTM resin is commonly used in various food packaging and various
packaging styles (film, cup, bottle and tube) for long shelf life.
EVALTM for milk product
UHT-milk pouch Yoghurt cup
Condense milkSmoothies
Flavored Milk
Flavored Milk
Milk powder for baby
WHAT IS UHT PROCESSING FOR MILK
PUT THIS IN
EVAL™
POUCH
PASTEURIZED VERSUS UHT MILK
WHAT IS UHT ?
UHT IS ULTRA HIGH
TEMPERATURE
STERILISATION
PROCESSING
TEMPERATURE OF
135 – 150 0C
PROCESSING TIME OF
1- 4 SECONDS
WHAT IS EFFECT OF UHT ?
KILLS BOTH MIRCO-
ORGANISMS AND SPORES
PRESENT IN MILK
PRESERVES AND RETAINS
MAXIMUM FLAVOUR ,TASTE
AND NURTITIONA L VALUE
GENERALLY SUITABLE FOR
LOW ACID PRODUCTS LIKE
MILK
EQUIPMENTS USED FOR UHT MILK PROCESSING
TYPICAL STERILIZER – HEAT EXCHANGER
TYPICAL ASEPTIC FFS MACHINE
COMPLETE UHT PLANT
EVAL TM FOR UHT MILK & ITS BENEFITS
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
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
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 ,
YOGHURT AND FRUIT JUICES
EVAL™ UHT POUCH VERSUS AL FOIL /PAPER CARTON
EVAL™ UHT POUCH VERSUS AL FOIL /PAPER CARTON
BENEFITS OF EVAL™ UHT MILK POUCHES
LOW PACKAGING COST AS COMPARED TO
CARTON , APPROXIMATELY ABOUT 33 %
LESS
BARRIER POUCH WEIGHS
MUCH LESS THAN THE
CARTON , APPROXIMATELY
JUST 6- 7 grams AS COMPARED
TO 24 grams FOR CARTON
SAVINGS IN PACKAGING AND TRANSPORTATION
COST CAN BE PASSED ONTO THE CUSTOMER
RESULTING IN PRICE REDUCTION FOR THE
CUSTOMER
