  • Types of Paper

    • Paper for writing and sketching
    • Square grid paper
    • Cartridge paper
    • Layout paper
    • Tracing paper
    • Grid paper
    • Bleed-proof paper
  • Paper
    Used for writing and sketching
  • Square grid paper

    • Useful for orthographic and scale drawings
    • Isometric paper is good for isometric drawings
  • Cartridge paper

    • High quality with textured surface, great for sketching with different drawing materials
  • Layout paper

    • Thin and translucent, used for general design work particularly sketching ideas
  • Tracing paper

    • Semi-transparent, used to copy images
  • Grid paper

    • May have a square or isometric pattern printed on it
  • Bleed-proof paper

    • Used by designers when drawing with felt-tips and marker pens, ink doesn't spread out (bleed)
  • Types of Board

    • Solid white board
    • Ink jet card
    • Corrugated card
    • Duplex board
    • Foam core board
    • Foil-lined board
  • Board
    Material above 200 gsm, also known as card or cardboard
  • Solid white board

    • High quality bleached surface, ideal for printing, used for primary packaging
  • Ink jet card

    • Designed so that ink doesn't bleed, allows for sharply defined high quality printed images
  • Corrugated card

    • Made up of a fluted inner core sandwiched between two outer layers, adds strength and rigidity, useful for secondary packaging
  • Duplex board

    • Different colour and texture on each side, often used for food packaging where only one surface is seen
  • Foam core board
    • Made by sandwiching expanded polystyrene foam between 2 thin layers of card, stiff, lightweight and can be scored
  • Foil-lined board

    • Board with an aluminium foil lining, keeps flavours in and air and moisture out, often used for food packaging
  • Ink bleeds on some paper because the paper fibres suck the ink
  • Paper weight

    Measured in gsm (grams per square metre), above 200 gsm it's considered board
  • Board is often used in packaging because of its low cost compared to other packaging materials, and its high strength-to-weight ratio
  • Wood types

    • Softwoods
    • Hardwoods
  • Softwoods
    • Grow in colder climates, fairly cheap and readily accessible, have leaves like needles and are usually evergreen with cones
  • Softwoods
    • Pine
    • Larch
    • Spruce
  • Hardwoods
    • Grow in warm climates, slow growing and generally more expensive than softwoods, have broad flat leaves and are usually deciduous
  • Hardwoods
    • Oak
    • Mahogany
    • Beech
    • Balsa
    • Ash
  • Spruce has a good strength-to-weight ratio but is also knotty and not very durable, used for structural purposes both outside and in
  • Balsa is a very soft hardwood with a very low density, but has a high strength-to-weight ratio, making it great for modelling
  • E board
    Strong, thick board that is good for printing on
  • E board is the only type of board recommended for direct contact with food
  • Making e board

    1. Bleached
    2. Coated with wax (or laminated with polyethylene)
  • Pulp used to make paper towels
    Treated with different resins during manufacture to increase its wet strength
  • This makes sure that the paper towels don't break when they become wet
  • Types of paper and board available

    • Various types (see p.16)
    • Bought by the sheet and in rolls (known as stock forms, see p.60)
    • Sold in standard sizes from AQ (1 m²) to A1, halving in size each time
    • Many other sizes available, e.g. A4 is half the size of A3, A5 is half the size of A4, etc.
    • Most common sizes used in schools are A4 and A3
    • Available in different weights, thicknesses and colours
    • Available in different plies (layers)
  • The width of A3 paper is the length of A4, and the length of A3 paper is double the width of A4
  • Recycled paper or board may not be suitable for use in food packaging
  • Useful properties for food packaging

    • Two properties
  • Additives added to paper and board
    To change the properties
  • Paper and board are commonly sold in stock forms (sheets and rolls)
  • Scissors
    Can cut paper and thin card, but not good for fine detail or removing bits from within a sheet
  • Guillotines and paper trimmers

    • Used to cut large sheets of paper and card, often many sheets at a time
    • Guillotines have a large blade that you push down to produce a straight cut
    • Paper trimmers use a smaller rotary blade to make straight cuts
  • Laser cutters

    • Machines that cut out designs drawn using CAD
    • Can make accurate and fine cuts through paper and card
    • Use a laser beam to burn away material
