CPT CPT Packaging Standards & Specifications 2 — Questions and Answers
Question 1: What is the primary purpose of a packaging specification document?
- To define requirements for materials, dimensions, and performance of packaging (Correct answer)
- To track the cost of packaging materials over time
- To record customer complaints about packaging defects
- To list all approved packaging supplier contacts
Correct answer: To define requirements for materials, dimensions, and performance of packaging
A packaging specification document formally establishes all measurable requirements that packaging must meet to be approved for use.
Question 2: What does GS1 standardize in the packaging industry?
- Barcodes and product identification systems (Correct answer)
- Glass container wall thickness
- Government safety labeling requirements
- Graphic design color standards
Correct answer: Barcodes and product identification systems
GS1 is a global organization that develops and maintains standards for barcodes, RFID, and electronic data interchange used in supply chains.
Question 3: What does the Cobb test measure for paper and board packaging materials?
- Water absorbency of paper and board surfaces (Correct answer)
- Compression strength of corrugated containers
- Oxygen transmission rate of coated films
- Color consistency of printed board
Correct answer: Water absorbency of paper and board surfaces
The Cobb test (TAPPI T441) measures the amount of water absorbed by the surface of paper or board under controlled conditions.
Question 4: What does OTR stand for in flexible packaging barrier specifications?
- Oxygen Transmission Rate (Correct answer)
- Optical Transparency Rating
- Outer Transit Resistance
- Overall Tensile Rating
Correct answer: Oxygen Transmission Rate
Oxygen Transmission Rate (OTR) measures how much oxygen passes through a packaging film per unit area per unit time, critical for shelf life.
Question 5: Which test method measures the burst strength of corrugated and solid fiberboard?
- Mullen Burst Test (Correct answer)
- Ring Crush Test
- Box Compression Test
- Edge Crush Test
Correct answer: Mullen Burst Test
The Mullen Burst Test (TAPPI T807) measures the hydrostatic pressure required to rupture a board sample and is a traditional box strength rating method.
Question 6: What does WVTR measure in packaging material specifications?
- Water Vapor Transmission Rate (Correct answer)
- Width Versus Thickness Ratio
- Weight and Volume Testing Result
- Warehouse Verification Testing Rating
Correct answer: Water Vapor Transmission Rate
Water Vapor Transmission Rate (WVTR) quantifies how much moisture passes through a packaging material, critical for moisture-sensitive products.
