CPT Packaging Innovation & R&D 3

Question 1

A packaging engineer is developing an oxygen-scavenging film for fresh meat. Which performance metric is most critical to quantify during R&D?

Accepted Answer

Oxygen transmission rate (OTR) reduction over time

Answer

OTR reduction over time measures how effectively the scavenger depletes headspace oxygen, which directly determines shelf life extension.

Question 2

Which analytical technique is most commonly used in R&D to identify the chemical composition of an unknown packaging material?

Accepted Answer

Fourier-transform infrared spectroscopy (FTIR)

Answer

FTIR identifies polymer types by matching their infrared absorption spectra against reference libraries, making it the standard tool for unknown material identification.

Question 3

During voice of the customer (VOC) research for a new packaging format, ethnographic observation differs from focus groups because it:

Accepted Answer

Captures actual consumer behavior in natural settings rather than stated preferences

Answer

Ethnographic observation records what consumers actually do in real environments, revealing unmet needs that self-reported focus group data often misses.

Question 4

A CPT candidate evaluates a nanotechnology-enhanced barrier coating for flexible packaging. Which primary regulatory concern must be addressed before commercialization in the U.S.?

Accepted Answer

FDA food contact safety for nanomaterials in food packaging

Answer

The FDA requires safety assessment of nanomaterials that may migrate into food, as their small particle size can alter toxicological profiles compared to bulk materials.

Question 5

In an R&D project targeting a child-resistant (CR) closure, which federal regulation governs the performance testing requirements in the United States?

Accepted Answer

CPSC 16 CFR Part 1700

Answer

The Poison Prevention Packaging Act, enforced by the CPSC under 16 CFR Part 1700, specifies the panel testing protocols for child-resistant packaging.
