What is the primary purpose of a packaging specification document?
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.
What does GS1 standardize in the packaging industry?
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.
What does the Cobb test measure for paper and board packaging materials?
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.
What does OTR stand for in flexible packaging barrier specifications?
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.
Which test method measures the burst strength of corrugated and solid fiberboard?
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.
What does WVTR measure in packaging material specifications?
Answer: Water Vapor Transmission Rate
Water Vapor Transmission Rate (WVTR) quantifies how much moisture passes through a packaging material, critical for moisture-sensitive products.
