What it is
Rail-transport packaging accounts for sustained vibration, coupling shocks, yard handling, long routes and transfers between rail and road terminals.
When it is relevant
Relevant for intermodal containers, swap bodies, wagon loads, heavy machinery and long continental corridors.
Risks and problems addressed
Longitudinal shocks, vibration, load shift, repeated crane or reach-stacker handling and terminal dwell can stress product and unit load.
Product characteristics that matter
State mass distribution, restraint points, shock and vibration sensitivity, stackability, dimensions and any liquid free-surface or moving masses.
Logistics and environmental factors
Map terminals, gauge or equipment changes, wagon/container type, route duration, shunting, intermodal lifts, storage and final road legs.
Information a packaging supplier needs
Provide the complete intermodal itinerary, shipment unit, handling lifts, acceleration and restraint assumptions, dwell, climate and acceptance criteria.
Common mistakes
Do not treat rail as road with different wheels, ignore shunting impacts, or specify the rail leg without terminal and road interfaces.
Relevant standards and regulations
ISTA procedures and ASTM Committee D10 publications are possible starting points for distribution testing. The suitable method and acceptance criteria must be selected for the real product-package-route system.
RFQ
What a useful specification contains
Provide the complete intermodal itinerary, shipment unit, handling lifts, acceleration and restraint assumptions, dwell, climate and acceptance criteria.
Frequently asked questions
How do I know whether rail-transport packaging requirements is relevant?
Relevant for intermodal containers, swap bodies, wagon loads, heavy machinery and long continental corridors.
What should I give a packaging supplier?
Provide the complete intermodal itinerary, shipment unit, handling lifts, acceleration and restraint assumptions, dwell, climate and acceptance criteria.
Does PackNavi choose a packaging technology here?
No. PackNavi captures conditions, required outcomes and open points. A suitable technology must be engineered and validated for the actual product and supply chain.
