CPE Package Design & Development 2 — Questions and Answers
Question 1: Which design principle refers to reducing the amount of packaging material used while maintaining product protection?
- Source reduction (Correct answer)
- Recyclability
- Biodegradability
- Lightweighting optimization
Correct answer: Source reduction
Source reduction is the practice of minimizing packaging material at the design stage without compromising protective function.
Question 2: In package development, what does DFM stand for?
- Design for Manufacturing (Correct answer)
- Design for Marketing
- Design for Material
- Design for Modularity
Correct answer: Design for Manufacturing
DFM (Design for Manufacturing) ensures that packaging can be produced efficiently and cost-effectively on existing equipment.
Question 3: A tamper-evident seal that shows visible signs of opening without the package being destroyed is classified as which type?
- Breakaway seal
- Full-panel label
- Shrink band (Correct answer)
- Blister pack
Correct answer: Shrink band
Shrink bands wrap around closures and show irreversible distortion when tampered with, providing visible evidence of tampering.
Question 4: What is the primary purpose of a dead-fold in flexible packaging design?
- To allow the package to hold its shape after folding without adhesive (Correct answer)
- To improve oxygen barrier properties
- To increase tensile strength
- To enhance heat-seal integrity
Correct answer: To allow the package to hold its shape after folding without adhesive
Dead-fold is the property that allows a flexible material to retain its folded position without needing a closure or adhesive.
Question 5: Which container shape provides maximum resistance to internal pressure for a given wall thickness?
- Square
- Rectangular
- Cylindrical (Correct answer)
- Triangular
Correct answer: Cylindrical
A cylindrical shape distributes internal pressure uniformly around the circumference, making it the most efficient shape for pressure resistance.
Question 6: In sustainable package design, 'Design for Disassembly' primarily aims to:
- Make multi-material packages easy to separate at end of life (Correct answer)
- Reduce assembly line complexity
- Lower consumer effort to open packaging
- Enable flat-pack shipping configurations
Correct answer: Make multi-material packages easy to separate at end of life
Design for Disassembly ensures that multi-component packages can be easily separated so each material can be properly recycled or recovered.
Question 7: Which factor most directly determines whether a corrugated fiberboard box will resist top-to-bottom stacking loads?
- Basis weight of the liner
- Box Compression Test (BCT) value (Correct answer)
- Bursting strength (Mullen Test)
- Caliper thickness of medium
Correct answer: Box Compression Test (BCT) value
The BCT value directly measures the maximum compressive load a completed box can withstand before failure, making it the primary stacking-strength indicator.
