CPT Distribution & Transportation Packaging Flashcards

What is the primary function of stretch wrap applied to a palletized load?

Answer: To secure and stabilize packages as a unified load during handling and transport

Stretch wrap holds individual cases together, prevents load shifting during transport, and provides minimal protection from dust and light moisture.

What is 'pallet overhang' in distribution packaging?

Answer: When cases or products extend beyond the edges of the pallet footprint

Pallet overhang reduces compression strength of bottom boxes, risks product damage from conveyor edges, and can create safety hazards in warehouse aisles.

Which mode of transportation typically subjects packages to the highest sustained vibration levels?

Answer: Over-the-road truck transport

Truck transport generates significant vibration across a broad frequency range due to road surface variability, suspension dynamics, and engine resonance.

What is 'vibration transmissibility' in cushion packaging design?

Answer: The ratio of vibration force transmitted through cushioning to the applied input force

Transmissibility values below 1.0 indicate attenuation (cushioning is working), while values above 1.0 indicate amplification of the input vibration.

What is the purpose of 'void fill' material inside a shipping carton?

Answer: To fill empty space and prevent product movement during shipping impacts

Void fill materials such as air pillows, paper fill, or loose fill prevent products from migrating inside the box and contacting box walls during drops or vibration.

What does 'palletization pattern' refer to in distribution packaging?

Answer: The arrangement of cases on a pallet to maximize stability and cube utilization

Palletization patterns such as column, brick, pinwheel, and row configurations balance interlocking strength, compression load distribution, and picking efficiency.
