Packaging Line Specification Checklist
The specification should make the required operating result measurable. It should also expose assumptions early enough for suppliers to resolve them before design and manufacture.

Turn the production need into a controlled brief
The specification should make the required operating result measurable. It should also expose assumptions early enough for suppliers to resolve them before design and manufacture.
A useful guide is not a substitute for product testing or competent project review. Its purpose is to structure the questions, expose assumptions and create comparable evidence. Record decisions in one controlled document and update it when samples, layouts or commercial boundaries change.
Scope and battery limits
Identify where the supplier scope begins and ends, including upstream product supply and downstream pallet or dispatch interfaces.
Performance definitions
Define speed, efficiency, changeover, reject handling and acceptable quality using clear test conditions.
Materials and formats
Control the dimensional range and quality of products, containers, closures, labels and secondary packaging.
Controls and data
State recipe, user access, batch, downtime, network and factory-system requirements.
Lifecycle support
Include manuals, training, critical spares, warranty, service response and obsolescence planning.
Information to document
The following checklist can be copied into an enquiry, user requirement or supplier-comparison sheet. Add units, ranges, sample references and responsible owners wherever possible.
- Process description and line diagram
- Approved SKU matrix
- Product safety and compatibility data
- Net output and operating calendar
- Inspection and rejection rules
- Floor plan and utility schedule
- Guarding and compliance responsibilities
- FAT/SAT protocols and documentation list
Use representative operating extremes
Include the smallest and largest packs, difficult products, closure and label variations, expected environmental conditions and the most demanding changeover. A line accepted only on an easy format may leave the real production risk untested.
Common planning mistakes
- 1Using ambiguous words such as “fast” or “easy” without a test
Resolve this in the written brief, supplier clarification or agreed acceptance plan.
- 2Specifying only nominal container dimensions
Resolve this in the written brief, supplier clarification or agreed acceptance plan.
- 3Failing to define who supplies integration signals and guarding
Resolve this in the written brief, supplier clarification or agreed acceptance plan.
- 4Accepting exclusions that leave essential line functions unowned
Resolve this in the written brief, supplier clarification or agreed acceptance plan.
Recommended next step
Issue the brief to suppliers in a consistent format, request a compliance response and make exclusions visible. Before order, close all high-risk assumptions or convert them into named tests, design reviews and contract deliverables. Before FAT, confirm materials, measuring methods and the exact acceptance sequence.
Packaging Line Specification Checklist FAQs
Is a URS the same as a quotation request?
A user requirement specification defines the operational need; the quotation explains how a supplier proposes to meet it and on what assumptions.
How detailed should the checklist be?
Detailed enough to make important outcomes testable, while allowing the supplier to engineer the best technical method.
Who should approve it?
Production, engineering, quality, safety, maintenance, procurement and relevant project owners should review the parts they will operate or support.

The line specification should make the production result and project boundary testable. Narrative requirements remain useful, but schedules help prevent an assumption about materials, services, controls or ownership from being hidden inside several machine quotations.
Packaging line scope and interface schedule
Complete each row with the actual project owner and evidence reference. Unknown information should remain an open action rather than being guessed.
| Schedule item | Minimum definition | Controlled project record |
|---|---|---|
| Incoming product | Condition, supply method, pressure or head, hopper or vessel boundary, temperature and product-change responsibility. | Process description and utility or product-connection schedule. |
| Primary pack and components | Approved formats, tolerance evidence, supply presentation, closure, label, code and secondary packaging. | Format matrix, component drawings or samples and change-control method. |
| Machine scope | Included process, inspection, reject, conveyors, accumulation, guarding and end-of-line functions. | Equipment and battery-limit list tied to the layout. |
| Mechanical interfaces | Working height, pack datum, transfer, guide, orientation, access and retained equipment. | Approved general arrangement and interface drawing. |
| Electrical and controls | Supply, panels, isolators, I/O, operating modes, recipes, data, networks and signal ownership. | Utility schedule, I/O list and controls philosophy. |
| Safety and conformity | Equipment boundary, competent risk work, guarding, safety functions, documentation and applicable marking or declaration responsibility. | Responsibility matrix and reviewed design record. |
| Acceptance and handover | Samples, FAT, SAT, good output, quality, changeover, documents, training, spares and action closure. | Approved protocol and delivery schedule. |
Utilities schedule headings
Do not invent loads before equipment data is available. The specification should define the information and connection boundary that must be completed during design.
| Utility or service | Information to record | Boundary question |
|---|---|---|
| Electrical | Voltage, phase, frequency, connected and operating load where available, isolator, cable route and earthing. | Who supplies and terminates distribution to each agreed connection point? |
| Compressed air | Pressure, quality, peak and typical demand where available, pipe size and local isolation. | Who provides treatment, distribution and capacity confirmation? |
| Extraction or ventilation | Contaminant or heat source, connection, duty to be engineered and discharge constraints. | Who designs the system and verifies performance for the actual process? |
| Water, drainage or cleaning | Quality, temperature, flow, connection, containment, drainage and cleaning method. | Where does machine scope end and site hygiene or effluent control begin? |
| Product services | Vessel, IBC, hopper or process feed, connection, return, recovery, heating or agitation requirement. | Who controls product condition and readiness at the machine boundary? |
| Data and network | Protocol, port, addressing, security, data owner, code source and remote-access rules. | Who approves connection and supports each side of the interface? |
Responsibility boundaries to sign off
Use named organisations or roles for the actual project rather than assuming the line integrator owns every activity.
- Site survey, layout accuracy, foundations, access, unloading and lifting.
- Production product, components, trial quantities, storage, waste and disposal.
- Retained machinery condition, modifications, software access and interface information.
- Utilities design, supply, connection, certification and availability for testing.
- Risk assessment, guarding boundary, technical documentation, declarations or marking and user obligations.
- FAT and SAT witnesses, instruments, quality release, training attendance, action closure and production handover.
Packaging line specification questions
How detailed should a packaging-line specification be before quotation?
It should define the production duty, approved range, layout and site constraints, interfaces, acceptance method and known open points well enough for suppliers to quote comparable boundaries. Format-specific details can remain controlled actions with decision dates.
What are battery limits in a packaging-line project?
They are the defined points where one supplier or party’s mechanical, electrical, controls, utility or process responsibility begins and ends. Record them on schedules and drawings rather than relying on the term alone.
Should unknown utility loads be estimated in the specification?
State the available site information and require confirmed supplier data during design. Do not publish guessed values as requirements; keep capacity confirmation as a named action before installation.
Use the related pages to document the product, pack, output, layout and acceptance evidence before requesting a detailed proposal.
Add an assumptions register and change-control route to the specification
A specification remains useful after quotation only when open information, supplier assumptions, exclusions and approved changes are visible. Give each item a reference, owner, closure method and link to the drawings, software, tooling or tests it can affect.
Unknown information should not disappear into general wording such as “subject to confirmation”. Record the condition used for design or pricing and the consequence if it proves different. This helps the project team close the highest-risk questions before they create rework or an incomparable quotation.
Keep the requirement status separate from responsibility. A supplier may propose a technical value while the customer provides the product or site evidence needed to approve it. The register should show both actions and the point at which the requirement becomes controlled.
| Register field | What to record | Closure evidence |
|---|---|---|
| Reference and requirement | Unique number, subject, source document and the production or project decision affected. | Traceable link to the current specification clause, drawing, format or interface. |
| Status | Confirmed, supplier proposal, to be verified, excluded, superseded or closed by approved change. | Dated status and the authority that accepted it. |
| Assumption or exclusion | The precise condition used, its limits and what is outside the quotation or design boundary. | Controlled sample, survey, supplier data, design review, contract clarification or approved exclusion. |
| Impact if different | Possible effect on process choice, output, tooling, controls, layout, utilities, risk work, cost, programme or testing. | Reviewed impact assessment rather than a generic “to be confirmed” note. |
| Owner and due stage | Named organisation or role, required input and the project gate that cannot proceed without closure. | Completed action with date and reference to the evidence supplied. |
| Decision and affected records | Approved result and every drawing, calculation, program, recipe, parts list, test or instruction that must change. | Reissued controlled documents and verification that the change was implemented. |
| Acceptance consequence | Whether a trial, inspection, FAT, SAT or other agreed check must be added or repeated. | Linked test case, result and action status. |
Use four clear requirement states during quotation and design
Confirmed
Supported by approved data, samples, drawings, survey or a recorded customer decision.
Supplier proposal
A stated technical approach or value awaiting review against the controlled duty.
To be verified
An open point with an owner, evidence requirement, impact and closure date.
Excluded
Clearly outside the offered boundary, with the party responsible for completing the missing scope identified.
Control changes after quotation
- Describe the changeState the revised requirement and why the current approved basis is no longer suitable.
- Assess the complete effectReview process, output, quality, interfaces, site works, safety, software, tooling, documents, cost, programme and acceptance.
- Approve before implementationName the people authorised to accept the technical and commercial effect and issue the new revision.
- Verify and closeUpdate affected records, inspect or test the change and link the evidence to the original requirement.
Include a controlled project deliverables schedule
- Production duty, format matrix, approved samples and change-part list.
- General arrangement, interface drawings, utility schedule and installation information.
- Controls philosophy, I/O or handshake records, recipe and backup arrangements.
- Risk-review outputs, guarding information, instructions and applicable responsibility records prepared by the competent parties.
- Trial plan, FAT and SAT protocols, results, deviations and action register.
- Manuals, drawings, backups, parts lists, training records and as-installed handover documents.
Assumption and change-control FAQs
What is the difference between an assumption and an exclusion?
An assumption is a stated condition used to continue design or pricing until it is verified. An exclusion is work or responsibility outside the offered scope. Both need a clear effect and owner, but only the assumption is expected to be confirmed or changed within the design basis.
Who owns open points in a packaging-line specification?
Assign the organisation or role that can supply the evidence or make the decision. Also name the supplier activity or project gate that depends on closure so the consequence of delay is visible.
When should the packaging-line specification be reissued?
Reissue it when an approved change affects the controlled production duty, scope, interface, layout, utilities, quality, safety, deliverables or acceptance method. Minor clarifications can remain in the register only if the governing requirement is unchanged.
Use the quotation comparison guide to compare boundaries, the layout guide to control the site basis and the FAT and SAT guide to prove the final requirement.
