Lightweight
Ductile
Malleable = easily pressed into shape
Good resistance to corrosion = will not rust
Good strength to weight ratio
Inert = will not react with the food contents
Good conductor of heat = can be used to cook food products
Can be printed on
Durable
Tough
Impervious to liquid
Steel packaging for food
• Steel is a ferrous metal and will therefore rust
• Relatively heavy so costs more to transport than
lighter materials
• Tough therefore it takes more energy / force to
deform when shaping containers
• Needs to be plated with tin to stop food coming
into contact with steel which adds an extra
process
• Extra material required increases production
costs
Advantages of Desk Top Publishing

Changes can be made easily / edited. Able to see what it looks like before making
it so that changes / errors can be corrected following feedback
Zoom / edit features / tools are easily used for attention to detail / proofing /
preview
Font / typefaces can be tested out to suit the style of product / package
Page layout grids / guides can be used to help position text / graphics / images
Can get consumer feedback so that any changes can be made before making
Documents can be saved electronically and sent to clients / printers
Accurate testing of product to see if it works / is the correct size
Reduced development time which saves money / gets product out to market faster
Make many/multiple models for testing
Templates / image libraries can be used saving time / not having to draw from
scratch
Lay planning can be used to help reduce waste
Colour separations / ‘bleed’ areas can be generated to aid printing process
Expanded Polystyrene
excellent impact resistance - it will absorb knocks / bumps / shock /
being dropped / protect product
lightweight - which means it will not cost too much to
ship/post/transport / makes it easier to carry
low water absorption - if it gets wet it will not soak up water and
damage product
easy to mould - allows for complex shapes to be protected

•
Made from oil which is a finite resource
Requires lots of energy to make
Difficult to dispose of as it degrades slowly and fills landfill sites
Gives off harmful fumes if burnt
Plastics – Vacuum Forming
•
•
•
•
•
•
•
•
•
A lightweight shell is formed from plastic
Hollow centres or cavities are formed in uniform shape
Relatively cheap to produce the mould
Surface textures and detail can be added
Each product formed will be identical
Moulds can be reused many times
Suitable for batch production
Cost effective
Examples include egg boxes, packaging for chocolates,
yoghurt pots, inserts for make up or toiletry gift sets
The mould is made from heat
resistant material. The shape is
tapered or chamfered to allow
easy release.
A heater is then applied onto the
HIPS plastic.
The mould is placed on the bed of the
vacuum former and is lowered.
The HIPS plastic then becomes
pliable / soft.
The HIPS plastic (High Impact
Polystyrene) is secured onto
the vacuum former.
The mould is raised and the
HIPs plastic takes the shape of
the mould. The air is removed
with the vacuum which sucks
air from underneath.
Finishing techniques
Hot foil blocking
• High quality / visual appearance /shiny gives it an increased value
• True reflective printing using foil that cannot be achieved with thermal inks
• Wasteful process / not environmentally friendly because only a little bit is used
/printed out
• Specialist equipment is required and is an expensive process which adds to overall
cost
• Heat involved which makes it a more expensive / time consuming process
Other finishes include
• Embossing – creating a raised area within a design to stand out from the
surface
• Varnishing / spot varnishing - A varnish is a liquid coating that is applied
to a printed document. The varnish can be Glossy, Matte or Satin giving a
variety of different finishes.
Spot varnishing is used to highlight a small element of the design
• Laminating – applying a plastic coating to paper or board to add a finish
(Glossy / matte / textured) and add strength.
Recycling
Remember the 6Rs to help you :
Reduce Reuse Recycle Repair Refuse Recover
But remember you will not get marks just for listing these. You will need
to give examples too.
• Recycled paper and board saves natural resources such as trees
• Reusing and recycling plastics reduces demand on finite resources
such as oil
• Recycling means less pollution due to incineration and less waste
going to landfill sites or less waste being dumped / fly tipping/
thrown into rivers
• Recovering and reusing materials reduces the impact on the
environment /landscape by not having to mine for new raw materials
• Less damage caused to wildlife/protection of sites / species
• Health risks from the break down of toxic materials are reduced
