CPP Packaging Testing & Performance 2

Question 1

Which test method is used to determine the top-load compressive strength of a corrugated fiberboard box (ECT)?

Accepted Answer

ASTM D642 measures the compressive strength of shipping containers under top-load conditions

Answer

ASTM D4169 measures only vibration and drop resistance

Answer

TAPPI T 802 measures only the burst strength of corrugated board

Answer

ASTM D1002 measures lap-joint shear strength of adhesives

Question 2

Oxygen Transmission Rate (OTR) testing of packaging films is critical primarily for:

Accepted Answer

Determining shelf life of oxygen-sensitive food products

Answer

Measuring the tensile strength of flexible films

Answer

Evaluating the heat resistance of barrier coatings

Answer

Calculating the recyclability index of multilayer structures

Question 3

The Moisture Vapor Transmission Rate (MVTR) is expressed in which unit of measurement?

Accepted Answer

g/m²/day

Answer

psi/inch

Answer

mL/cm²/atm

Answer

N/15mm

Question 4

In a peel strength test for packaging seals, what does a higher peel force value indicate?

Accepted Answer

A stronger seal that requires more force to open

Answer

A weaker seal that is more susceptible to temperature cycling

Answer

A lower oxygen transmission rate through the seal area

Answer

Greater flexibility of the packaging film

Question 5

Before conducting climate-sensitive packaging tests, samples are typically conditioned at 23°C and 50% relative humidity. What is the purpose of this pre-conditioning step?

Accepted Answer

To equilibrate samples to a standard reference state so results are reproducible and comparable

Answer

To accelerate the aging of packaging materials before mechanical testing

Answer

To simulate tropical storage conditions relevant to export markets

Answer

To activate the moisture barrier coating on the packaging material

Question 6

A 'hazard profile' in packaging distribution testing refers to:

Accepted Answer

A documented description of the specific transportation modes, handling steps, and environmental conditions a package will encounter

Answer

A regulatory filing that identifies dangerous goods classification for a package

Answer

A material safety data summary for packaging chemicals used in printing

Answer

A risk register listing potential packaging design defects

Question 7

The Edge Crush Test (ECT) value of a corrugated board is used primarily to predict:

Accepted Answer

The stacking strength of boxes made from that board when subjected to top-load compression

Answer

The puncture resistance of the corrugated board face sheets

Answer

The moisture absorption rate of the corrugated medium

Answer

The adhesion strength between the liner and the medium
