Question 1: Describe the main differences between cardboard and paperboard in terms of their typical thickness, strength, and common uses.

Answer: Cardboard is thicker, generally more rigid, and used for packaging and boxes, while paperboard is thinner, more flexible, and used for cartons and folding boxes. Cardboard offers higher strength and durability compared to paperboard.

Question 2: Identify two types of papers that are suitable for use in making decorative greeting cards and explain why.

Answer: Cardstock and textured paper are suitable because they are thick and sturdy, providing a premium feel and allowing for embellishments and printing without tearing easily.

Question 3: Explain the differences between kraft paper and bleached paper in terms of appearance, strength, and typical applications.

Answer: Kraft paper has a natural brown colour, is strong and durable, and is used for packaging and wrapping. Bleached paper is white, softer, and used for printing, writing, or decorative purposes.

Question 4: Sketch a design for a simple, eco-friendly packaging box made from recycled paperboard. Include labels for key features such as flaps, tabs, and locking mechanisms.

Answer: A correct sketch would show a rectangular box with fold lines, flaps for closing, tabs for locking, and sections labeled to indicate the use of recycled paperboard. The design should be simple, with clear fold lines and closure features.

Question 5: Design a layered cardboard structure intended for a lightweight display stand. Include a basic plan showing how the layers are arranged and bonded.

Answer: The plan should depict multiple layers of corrugated cardboard bonded together in a stacked arrangement, with flaps or tabs for assembly. The layers should be shown with their orientation and bonding points for strength.

Question 6: Discuss the environmental advantages of choosing recycled paper and board materials in product design.

Answer: Recycled paper and board reduce waste in landfills, lower the demand for virgin materials, conserve natural resources, and often require less energy to produce, making them more sustainable.

Question 7: Identify two challenges that might be faced when using thick paperboard for detailed packaging designs, and suggest possible solutions.

Answer: Challenges include difficulty in achieving fine detail cuts and increased weight. Solutions could be using precision cutting tools and designing with lightweight board options to reduce weight.

Question 8: Create a brief plan for testing the strength of a new paperboard material intended for packaging. Include at least two different tests you would perform.

Answer: Tests could include a burst strength test to measure resistance to pressure and a bend test to assess flexibility and durability when folded or handled.

Question 9: Imagine you need to create a display board for an exhibition using only paper and board materials. Outline your initial ideas for the structure and how you would ensure stability.

Answer: The structure could include a sturdy base, vertical supports, and layered panels. Stability can be ensured by using wide bases, interlocking joints, and reinforcement with additional layers or supports where needed.

Question 10: Draw a concept sketch for a foldable brochure made from paperboard that can be easily assembled and disassembled. Label the fold lines and key features.

Answer: A correct sketch would show a flat sheet with clearly marked fold lines, tabs or slots for assembly, and a design that allows the brochure to fold into a compact, display-ready form. The sketch should include labels for folds, tabs, and any locking features.
