Papers and boards
This topic covers the categorisation, properties, and applications of papers, cards, boards, and composite materials, including their standard sizes, measurement systems, and manufacturing processes.
Topic Overview
Papers and boards are fundamental materials in design and technology, encompassing a wide range of products from packaging and books to furniture and structural models. This topic covers the properties, classifications, and manufacturing processes of paper and board, including their environmental impact and sustainability. Understanding these materials is crucial for making informed design decisions, as they offer versatility, cost-effectiveness, and recyclability.
In the WJEC GCSE Design and Technology course, 'Papers and boards' is a core material area within the 'Core technical principles' and 'Specialist technical principles' sections. Students explore different types of paper (e.g., cartridge, layout, tracing) and board (e.g., corrugated, solid white board, foil-lined board), learning how their properties—such as weight, thickness, finish, and strength—affect their suitability for specific applications. This knowledge is applied in designing and making prototypes, considering factors like printing techniques, cutting, scoring, and folding.
Mastering papers and boards enables students to create effective, sustainable packaging solutions and paper-based products. It also links to broader topics like material selection, manufacturing processes, and environmental issues, preparing students for both the written exam and the non-examined assessment (NEA). By understanding the lifecycle of paper products—from raw material sourcing to disposal or recycling—students can design with sustainability in mind, a key requirement of modern design practice.
Key Concepts
Core ideas you must understand for this topic
- →Classification of paper and board by weight (gsm) and thickness (microns), e.g., paper up to 200 gsm, board above 200 gsm.
- →Properties: grammage, thickness, finish (coated/uncoated), stiffness, tear resistance, and absorbency, and how these affect use.
- →Common types: cartridge paper (drawing), layout paper (sketching), tracing paper (overlays), corrugated board (packaging), solid white board (boxes), and foil-lined board (food packaging).
- →Manufacturing processes: die-cutting, scoring, creasing, folding, and laminating, plus printing methods like lithography and flexography.
- →Environmental impact: sourcing from sustainable forests, recycling symbols (e.g., Mobius loop), biodegradability, and the importance of reducing, reusing, and recycling.
What You Need to Demonstrate
Key skills and knowledge for this topic
- Categorisation and properties of paper, cards, boards, and composite materials (strength, folding ability, surface finish, absorbency).
- Lamination techniques to improve strength, finish, and appearance.
- Standard ISO paper sizes.

Examiner Tips
Expert advice for maximising your marks
- 💡Be prepared to justify the selection of a specific paper or board based on its functional and aesthetic properties.
- 💡Understand how to calculate material quantities and costs for products.
- 💡Relate the properties of materials to their specific end-use in commercial products.
- 💡When describing properties, always link them to a specific application. For example, 'Corrugated board has high stiffness and cushioning, making it ideal for protective packaging.' This shows you understand the relationship between material and function.
- 💡In the exam, be precise with terminology. Use 'grammage' (gsm) instead of 'weight', and 'die-cutting' instead of 'cutting out'. This demonstrates technical knowledge and can earn you higher marks.
- 💡For sustainability questions, mention the full lifecycle: sourcing (FSC certified), manufacturing (energy use), use (durability), and end-of-life (recyclability). Avoid vague statements like 'it's good for the environment' without evidence.
Common Mistakes
Pitfalls to avoid in your exam answers
- Confusing the measurement units for paper (gsm) and card (microns).
- Failing to distinguish between the functional and aesthetic properties of different board types.
- Overlooking the importance of lamination in improving structural integrity.
- Misconception: All paper and board are the same. Correction: Paper and board vary widely in weight, thickness, finish, and strength, making them suitable for different applications. For example, corrugated board is strong for packaging, while cartridge paper is better for drawing.
- Misconception: Paper and board are not environmentally friendly. Correction: While they come from trees, many papers and boards are made from recycled materials or sustainably sourced wood. They are biodegradable and recyclable, making them more eco-friendly than many plastics.
- Misconception: Scoring and creasing are the same thing. Correction: Scoring is a cut or indentation to weaken the board for folding, while creasing is a compressed line that allows a clean fold without cracking. Creasing is preferred for thicker boards to avoid damage.
