Passenger service bags are not interchangeable
Airsickness bags are often procured around containment and user handling, while train or coach waste bags may be specified for dry cabin waste or seat-pocket convenience. Buying both solely by paper weight or visible dimensions can hide important performance differences.
A purchasing brief should describe the cabin environment, use case, user instructions, storage method, replenishment cadence and relevant testing requirements.
Identify the use and required evidence
| Decision | Airsickness bag | Train or coach waste bag |
|---|---|---|
| Expected contents | Define intended liquid or mixed-content exposure | Usually define dry waste; require separate tests for any liquid use |
| Bag closure | Discuss fold, tab or closure feature | Discuss how users carry and discard |
| Construction | Specify lining, seam and barrier requirements | Specify paper strength and opening design |
| Storage | Seat-pocket fit and folded thickness | Seat-pocket or service-cart packing format |
| Printing | Language, pictograms and disposal instructions | Operator branding and user guidance |
Containment and claim boundaries
An illustrative product photo does not establish liquid containment. For an airsickness application, agree a test method, fill level, dwell time, closure configuration and inspection sampling with the supplier. Different test fluids and durations can produce different outcomes.
Do not use a single paper or coating test report as automatic evidence that every assembled bag is leakproof. Request product-specific inspection and release criteria if containment matters.
- Folded dimensions, carton pack count and number of units per cabin.
- Instructions, languages, airline brand artwork and proof approval.
- Change management for recurring procurement and consistent bag revisions.
- Destination-market and airline-specific documentation requirements.
Plan repeat purchasing around an approved sample
Seat-pocket dimensions, artwork revision and approved bag construction should remain traceable between initial sampling and later orders. Maintain written acceptance requirements so a packaging change does not introduce an avoidable operational mismatch.

Buyer questions worth resolving
Are transport waste bags suitable for liquids?
Not by default. If liquid exposure is a requirement, define and validate it for the exact finished structure.
What is needed for an airline RFQ?
A target folded bag size, contents/use case, closure, tested containment target, print files, estimated usage and packing requirements.
Prepare a useful sourcing brief
A clear inquiry gives a supplier the intended use, format, material and testing questions—not just a target price. Include your destination market, drawing or sample, print design, order forecast and acceptance criteria.
