Worldwide Trends: Water & Packaging

Water covers 70.9% of the Earth's surface, and is vital for all known forms of
life.
Water is transparent liquid
Water may be in liquid, ice or vapour/steam formulations
Water fit for human consumption is called drinking water or potable water.
Water that is not potable may be made potable by filtration or distillation, or
by a range of other methods.

Worldwide Trends: Water & Packaging
•
The human body contains from 55% to 78% water, depending on body size.
To function properly, the body requires between one and seven liters of water
per day to avoid dehydration
•
Humans require water with few impurities. Common impurities of water
include metal salts and oxides, including copper, iron, calcium and lead,
and/or harmful bacteria, such as Vibrio. Some solutes of water are
acceptable and even desirable for taste enhancement and to provide needed
electrolytes

Worldwide Trends: Water & Packaging forms

•
Water packages: Drinking water & food packages
Drinking water is obvious article to be packed
Also noted is that normally, about 20% of water intake of human being comes
from food, while the rest comes from drinking water and beverages
(caffeinated included).
•
Water in food is not so demanding material to be packed than pure liquid
drinking water because in food it is part of packed food matrix with some
taste or aroma compounds already.
Water in food set also high level demands for water holding capacity of food
material itself and also qritical requirements for used packaging materials to
keep humidity or liquid water inside the package or allow in the other hand
water/humidity/steam to go in and out from the package into outside
environment to keep packed food in a good form and fresh look.

Odour & Taste of Water
•
Water can dissolve many different substances, giving it varying tastes and
odors. Humans and other animals have developed senses that enable them
to evaluate the potability of water by avoiding water that is too salty or putrid.
The taste of spring water and mineral water, often advertised in marketing of
consumer products, derives from the minerals dissolved in it. However, pure
H2O is tasteless and odorless. The advertised purity of spring and mineral
water refers to absence of toxins, pollutants and microbes, not the absence
of naturally occurring minerals.
•
•
Drinking water is a very demanding product to be packed.
Water can take off-odours and off-tastes directly from the contacts of other
materials
Water can take off-odours and off-tastes through open air without direct
contact

•
Packaging demands
– To cover the commercial product in to the right size for customers to buy
– To protect the packed material in right way
•
•
•
•
•
•
To allow transportation of packages into to the markets
To maintain packed matrix free off-odour and off-taste
To maintain packed matrix free of microbes and other safety threats
To maintain packed matrix self-life as set in production
To keep packed matrix in good shape in customer environment (car, home, trip, etc.) until
used as set
Packaging materials:
–
–
–
–
Fossil based polymers
Bio based polymers
Composite structures (Fiber + polymer/bio-polymer combinations)
Tomorrow challange: fiber based (wood based) materials and biopolymers
