Question 4

What does a 'coefficient of friction' (COF) test measure in flexible packaging?

Accepted Answer

The resistance to sliding between two packaging surfaces, affecting machinability and stacking

Answer

The ratio of tensile strength to elongation in a packaging film

Answer

The permeability of a film to gases at standard conditions

Answer

Question 5

A package that passes a 'stacking test' under ASTM D4169 demonstrates that it can:

Accepted Answer

Withstand compressive loads simulating the weight of packages stacked above it during warehousing

Answer

Survive repeated freeze-thaw cycling without seal failure

Answer

Maintain product integrity during automated sortation systems

Answer

Resist impact from forklift tines during warehouse operations

Question 6

The Dye Penetration Test (ASTM F1929) is used specifically to detect:

Accepted Answer

Leaks and channel defects in heat-sealed flexible package seals

Answer

Pinholes in metallized barrier films

Answer

Microbiological contamination at package seams

Answer

Oxygen permeation through polymer packaging films

Question 7

In packaging testing, what is the significance of the Q10 factor used in accelerated aging calculations?

Accepted Answer

It represents the ratio of reaction rates for every 10°C increase in temperature, used to calculate real-time aging equivalence

Answer

It is the safety factor applied to top-load compression test results for corrugated boxes

Answer

It defines the minimum number of samples required for statistical validity in drop testing

Answer

It is the standardized oxygen transmission rate threshold for food-grade barrier films
