YesterdAY
In early days, when we think of milk, we think of the days of milkmen delivering
fresh dairy goods in the glass bottles to the door early in the morning.

12. MILK PACKAGING YesterdAY
Why milk packaged in Glass????
Transparent
Strength
Rigidity
Water and Gas Barrier
 Thermal Shock Resistance
Inertness to Chemical Substances
 Cheap Cost
 100% Recyclable

Shifting from Glass to HDPE Containers
02/16/13 INDIAN INSTITUTE OF PACKAGING 13

14. MILK PACKAGING YesterdAY
Reasons to Shift from Glass to HDPE Containers
 Heavy Weight
It occupies more space during transportation and storage
 Fragility
Due to fragile nature it needs more protection from external hazards
 Cost
Though material cost is less, it increase the cost of transport and storage
which leads to more fuel consumption
Contd..

15. MILK PACKAGING YesterdAY
Material Consumption
For packaging of 500 ml milk we need 500 g of glass material
 Effect of Light
Light damages the nutritive components of milk
 Chemicals
Effect of chemicals for washing the bottle leads to environmental hazard.
02/16/13 INDIAN INSTITUTE OF PACKAGING 15

16. MILK PACKAGING YesterdAY
Reasons for Selecting HDPE Bottles
 Need only 40 g of HDPE to pack 500 ml milk
 Good ESCR
 Good Impact Strength
 Good moisture barrier
02/16/13 INDIAN INSTITUTE OF PACKAGING 16

17. MILK PacKagIng YesterdaY
Reasons to shift from HDPE bottles to Cartons/Pouch
 Bottle is a single use container
 Recycling of bottles become cost factor
 If we try to recycle then it has to be washed and sterilized and rebroken down
into size which can be fed into extruder.

Reasons for selecting Flexible Pouch (POLY)
Cheapest in the world
 Easy to handle
 Occupies less space
 Convenient
 Recyclable
 Use lowest amount of Packaging Material : 4.5 -5.5 g
 Bottles don’t need to be collected, washed, refilled and
redistributed

25. MILK PACKAGING ToMorrow
Thermoformed bottle is made from Poly Lactic Acid (PLA)
PLA is derived from natural corn starches
100% annually renewable
02/16/13 INDIAN INSTITUTE OF PACKAGING 25

26. AdvANTAGes of PLA
PLA degrades within weeks
High stability
Transparency
Softening point around 60 degree
Normal processing
Good thermoplastic material
Wide temperature range
Lower Crystallinity
Higher melt viscosity
UV resistance
