|Study the mobile phone packaging seen below.|
|1. Explain why high quality card is needed to manufacture the box.|
|High quality card will
ensure that the colours printed on its surface, will appear bright and
sharp. Quality card has a superior feel when handled by potential
customers, suggesting that there is a quality product inside the
Good quality card is less flexible than cheaper card and can be scored and folded without the surface breaking or being damaged. Flat surfaces hold their shape and are less likely to warp, crease or bend out of shape.
Printing adheres more accurately to good quality card because the cards surface is resistant to bending and breaking. This gives a flat surface on which to print.
|2. Name a material that is suitable for the polymer insert of the mobile phone packaging.|
|High Impact Polystyrene (HIPS).|
|3. Why is the material you have named, the most suitable?|
|High Impact Polystyrene
(HIPS) is the most suitable as it is available in transparent form and can
be moulded accurately, to the shape of the insert.
Vacuum forming is the manufacturing process through which the shape can be manufactured.
HIPS can be recycled relatively easily, if disposed of in the relevant recycling bin. HIPS has a short life cycle.
|4. List other polymers that could be used for the polymer insert.|
|Other materials that
could be used are:
Plastic forming films such as polyvinyl chloride (PVC), polypropylene (PP) and polyester (PET) are formed through the use of heat, and are usually colourless and transparent.
