Food Packaging
COT-Packaging Materials ppt.pptx
The main aims of packaging are to keep the
food in good condition until it is sold and
consumed, and to encourage customers to
purchase the product.
What do you think is the main aims of
food packaging?
•Provide a barrier against dirt
and other contaminants thus
keeping the product clean .
•Prevent losses. For example,
packages should be securely
closed to prevent leakage
FUNCTIONS OF GOOD
PACKAGING
•Protect food against physical and
chemical damage. For example
the harmful effects of air, light,
insects, and rodents. Each
product has its own needs.
• Package design should provide
protection and convenience in
handling and transport during
distribution and marketing
Help the customers to
identify the food and
instruct them how to use it
correctly.
Persuade the consumer to
purchase the food.
•Marketing - The
packaging and labels can
be used by marketers to
encourage potential
buyers to purchase the
product.
Correct packaging prevents
any wastage (such as leakage
or deterioration) which may
occur during transportation
and distribution
• Leaves
• Vegetables fibers
• Wood
• Papers, newsprint
• Earthenware
• Glass
• Plastics
• Metals
TYPES OF FOOD PACKAGING
Leaves
Banana leaves are often used for
wrapping certain types of food
(e.g. suman). Corn husk is used to
wrap corn paste or unrefined
block sugar, and cooked foods of
all types are wrapped in leaves.
Vegetable Fibers
These include bamboo, banana,
coconut, and cotton fibers. These
natural materials are converted into
yarn, string or cord which will form
the packaging material. These
materials are very flexible, have
some resistance to tearing, and are
lightweight for handling and
transportation.
Wood
Wooden shipping containers
have traditionally been used for a
wide range of solid and liquid
foods including fruits, vegetables,
tea and beer. Wood offers good
protection, good stacking
characteristics and strength.
Paper
Paper is an inexpensive
packaging material. It is
however highly absorptive,
fairly easily torn, and offers
no barrier to water or gases.
Earthenware
Earthenware pots are used
worldwide for storing liquids and
solid foods such as curd, yoghurt,
beer, dried food, and honey.
Corks, wooden lids, leaves, wax,
plastic sheets, or combinations of
these are used to seal the pots.
Glass
Glass has many properties which make it a popular choice as a packaging
material
 Glass is able to withstand heat treatments such as
pasteurizationand sterilization.
 Does not react with food.
 Protects the food from crushing and bruising
 Resistant to moisture, gases, odors and
microorganisms
 Re-usable, re-sealable and recyclable
 Transparent, allowing products to be displayed.
Colored glassmay be used either to protect the food
from light or to attract customers.

Answer the
questions but
there is mistake.
All answer is
incorrect.
Types
of
food packaging
Example & uses Advantages disadvantages
Leaves Banana leaves and corn husk – are
often used for wrapping certain
types of foods.
It can be used in wrapping all
types of cooked foods.
They do not however
protect the food against
moisture, oxygen odors
or micro-organisms.
Not suitable for long
term storage.
Vegetables fibers These include bamboo, banana
coconut and cotton fibers-are
converted into yarn, string or cord.
these materials are very
flexible, some resistance to
tearing, and are lightweight for
handling and transportation.
Do not provide
protection to food from
moisture pick up,
micro-organisms and
insect or rodents.
wood Wooden crate/
Wooden shipping containers have
traditionally been used for a wide
range of solid and liquid foods
including fruits, vegetables, tea
and beer.
Wood offers good protection,
good stacking characteristics
and strength.
The use of wood continues for
some wines and spirits because
the transfer of flavor
compounds from the wooden
barrels improves the quality of
the product.
Highly cost
Papers, newsprint Newsprint -should be used only as
an outer wrapper and not be
allowed to come into direct
contact with food, as the ink used
is toxic.
Paper is an inexpensive
packaging material.
It is however highly
absorptive, fairly easily
torn, and offers no
barrier to water or
gases.
Group 1
Types of
food packaging
Example & uses Advantages disadvantages
Earthenware
Earthenware pots are used
worldwide for storing liquids and
solid foods such as curd, yoghurt,
beer, dried food, and honey.
Costly and easy to break.
glass
Glass container- popularly choice as a
food packaging material.
• Glass is able to withstand heat treatments such as
pasteurization and sterilization.
• Does not react with food.
• Protects the food from crushing and bruising
• Resistant to moisture, gases, odors and
microorganisms
• Re-usable, re-sealable and recyclable
• Transparent, allowing products to be displayed.
Colored glass may be used either to protect the
food from light or to attract customers.
• glass is heavier than many other packaging
materials and this may lead to higher transport
costs
• it is easy to fracture, scratch and break if heated
or cooled too quickly
• potentially serious hazards may arise from glass
cracks or fragments in the food.
Plastics The use of various plastics for
containing and wrapping food
depends on what is available. Plastics
are extremely useful as they can be
made in either soft or hard forms, as
sheets or containers, and with
different thickness, light resistance,
and flexibility.
• Cost is relatively low.
• Good barrier properties against moisture and
gases.
• Heat sealable to prevent leakage of contents.
• Have wet and dry strength.
• Easy to handle and convenient for the
manufacturer, retailer, and consumer.
• Little weight to the product.
• Fit closely to the shape of the product, thereby
wasting little space during storage and distribution.
offers no barrier to fire.
Metal
Metal cans – used as containers.
• Metal cans provide total protection of the contents.
• Metal cans are tamper proof.
• Metal cans are convenient for presentation.
• heavier than other materials, except glass, and
therefore have higher transport costs
• the heat treatment associated with the use of
metal cans is not suitable for small-scale
production.
