What would typically be in a small
childs lunch box?
Important topics to revise:
The difference between ergonomics and anthropometrics.
The difference between sustainability, recyclable and renewable.
Materials, in particular, papers, board and card.
Production methods in particular: Batch production.
Practice designing a disposable and reusable lunch box.
Appealing to a
small child:
Bright
colours,
simple shape,
cartoons.
Characters, simple shapes and bold
bright colours would be used to
attract the small child to the food
to make it look exciting and fun to
eat.
Could your design have a dual
purpose? Two functions? Eg,
educational facts? Chalk board?
Puzzles included etc?
Food packaging materials: Card/Paper/Board
Wax coated paper: Waxes are used to make wax paper this coats
the paper and card to waterproof it or make it resistant to
staining, or to modify its surface properties. For example this
would prevent card from getting soggy from a sandwich.
White board is used for packaging because its hygienic, printable,
and has a satin finish which makes the product look clean which is
important when packaging food.
Window to see the sandwich, made from corn starch. This allows
the customer to see the product and it also makes the product look
more expensive and attractive.
Theme:
Packed lunch containers
These can be
reusable or
disposable.
Does this information appeal
to the parent/carer or the
child? Why is it needed?
Disposable packaging creates
a lot of waste. Why is it
important that these logos
are used on the packaging?
Recycling, keep britain tidy,

Anthropometrics is the study of the sizes of people in
relation to products. For example, chairs used in schools need
to be suitable for the average size of pupils in the schools. A
small child has small fingers, would they struggle opening a
clasp on a packed lunch box? Anthropometric data is used to
help design products
Batch production is when a small quantity of
identical products are made. Batch production may
also be labour intensive, but jigs and templates are
used to aid production. Batches of the product can
be made as often as required. The machines can be
easily changed to produce a batch of a different
product.

A typical
batch
produced
product.
Ergonomics is the
relationship between
people and the
products which they
use. Is it comfortable?
Will it create health
problems in later life?
Everyone has a different role
which they repeat on every
product to make a batch.
Sustainable energy is the
sustainable provision of energy that
meets the needs of the present
without compromising the ability of
future generations
Recycling is a process using materials
(waste) into new products to prevent
waste of potentially useful materials
A renewable resource is a natural resource which can
replenish with the passage of time, either through biological
reproduction or other naturally recurring processes
Polypropylene recycling
symbol, indicates that
this type of plastic can
be recycled.
Healthy eating symbols, ‘pressed into the polypropylene casing.
Symbol ‘A’ is promotes foods related to a healthy heart. Symbol
’B’ relates to eating fruit and vegetables

Materials for packed lunch containers.
Material: Polypropylene is a thermoplastic polymer, ideal for the
manufacture of reusable containers, such as packed lunch
containers. It cis an hygienic material as it can be washed easily and
resists stains. It is tough, flexible and durable, withstanding every
day drops and knocks. it is supplied in a range of colours.
Polypropylene offers good resistance to fatigue.
Material: PET / PETE is a thermosetting polymer and has good
physical properties of strength , ductility, stiffness and hardness.
PET / PETE is 100% recyclable. It is light weight and can be
crushed / compressed, making it easy to transport to recycling
plants. Most supermarkets have collection points. It is supplied in a
range of colours
Polymers / plastics have a reputation of being environmentally
unfriendly. They take years and in some cases centuries to decay.
However, plastic bags made from Polylactide (PLA) take only five
years to decompose. Containers such as drinking bottles and food
containers manufactured from PLA, take slightly longer to decay, as
they are manufactured from thinker material.
Polylactide is referred to as a ‘bioplastic’ because of its
environmentally friendly nature.
Manufactured from a food safe material,
polypropylene (PP). Free from chemicals
such as BPA, PVC and Phthalates.
Injection moulded.
Clips hold the lid tightly shut and contents
sealed in. Secure food storage.
Handle for carrying the container.
Drop resistant, relatively unbreakable.
Three part construction (two lids/sides and
body/casing), allows easy access.
Has three integrated divides, for
separating different foods.
Embossed lid, simple logo/symbol.

PAPER AND CELLULOSE FILM
This type of packaging material is easy to print
on and can be coated, treated or laminated.
Often it is manufactured from renewable
materials (recycled paper and pulp).
It is easy to handle and lightweight. In addition
it can be folded into a variety of shapes by
machines or by hand.
In general it is used for labels, cartons, boxes
and wrappings
Lithography printing process
1. The printing plate has the
image to be printed, in relief,
on its surface (the image
stands out slightly from the
printing plate surface).
2. The printing plate is kept
dampened. Ink is applied to
the plate but it is repelled
from the dampened surfaces
which are the non-image areas.
3. As the printing cylinder
rotates the ink is transferred
to the rubber blanket cylinder.
4. The ink, now on the rubber blanket cylinder, is pressed onto the paper or card as
it is pulled through the machine. (The paper is trapped between the blanket cylinder
and the impression cylinder - these pull the paper through the machine).
The difference between British
Standards and European Standards.
The European Community sets minimum
standards of safety and manufacturing quality,
that apply across all member countries of the
EEC. Manufacturers working to this ‘lowest’
limit, can display the CE symbol on their
products. Minimum standards have been
established, that apply to a vast range of
products, ranging from toys to motor vehicle
components. Manufacturers must ensure, that
their products at least meet these minimum
standards or risk having them removed from
the shelves of retailers throughout Europe.
Screen printing process used
on packed lunch containers:
Screen printing is a technique, that
can be used to add colour paints and
inks to a range of materials from
card and textiles to polyethylene.
The example below, shows how
simple shape, cut into a template can
be used to transfer paint / ink to a
polyethylene lid.
Once one colour is dry, a second and
third and even more layers of colour
can be added, using the same screen
printing technique
Products that have a British Standards
Institute (BSI) Kite Mark stamped on them,
have been checked for safety and quality of
manufacture, by the BSI. The Institute
carries out strict tests, that have been
designed to ensure that the product is safe
and has been manufactured to a high
standard. The BSI Kite Mark is respected
throughout the world. If a product being
tested meet British Standards, the
manufacturer is issued with a licence, allowing
the use of the Kite Mark.
