How to Prepare a Packaging Machine RFQ: A Buyer’s Checklist

A useful packaging machine RFQ does more than ask for price and maximum speed. It defines your product, package, production target, site constraints, interfaces, and acceptance method clearly enough for suppliers to quote the same job. This guide shows how to turn those inputs into a comparable, testable request for quotation.

What Should a Packaging Machine RFQ Achieve?

A packaging machine request for quotation should create a shared definition of the application. The buyer states what the finished process must accomplish and where the limits are. The supplier then identifies a machine route, filling system, options, exclusions, utilities, and validation plan that address those requirements.

That distinction matters. If you specify only a machine name, each supplier may make different assumptions about the product, pouch, speed, operator tasks, inspection equipment, and line interfaces. The resulting prices can look comparable while describing materially different scopes.

Your RFQ should make four outcomes possible:

• Suppliers can identify missing information before preparing a proposal.
• Alternative machine concepts can be compared against the same operating need.
• Optional equipment, third-party items, and buyer responsibilities remain visible.
• Factory acceptance testing can use criteria agreed before the machine is built.

RFQ principle: Define the required result and operating conditions first. Let each supplier explain how its proposed configuration will achieve and verify that result.

1. Describe the Product as a Process Input

Begin with the product that will pass through the filler and package, not with a preferred machine model. State the product name and physical form: free-flowing granule, fragile solid, dusty powder, liquid, viscous paste, suspension, or mixed product. Add the properties that can change feeding, dosing, sealing, cleaning, and material selection.

Depending on the application, relevant inputs may include:

• Minimum, normal, and maximum particle size or piece dimensions
• Bulk density and expected variation between batches
• Flowability, dust generation, tendency to bridge, or static behavior
• Liquid viscosity at the actual filling temperature
• Foaming, stringing, dripping, settling, or solids in suspension
• Product temperature, moisture sensitivity, or oxygen sensitivity
• Abrasive, corrosive, sticky, or fragile behavior
• Allergen, cross-contamination, or sanitation constraints

Do not write only “powder” or “sauce.” Two products in the same category can require different hoppers, agitation, dosing methods, product-contact materials, cut-off devices, and cleaning access.

Include representative product samples when practical. A supplier can use them to evaluate flow, dosing stability, residue, seal-area contamination, and product behavior during a trial. Identify whether the sample represents normal production or an easy laboratory batch. If your raw material varies by season or supplier, include the expected range rather than one ideal sample.

2. Define Every Pack Format and Packaging Material

State whether the machine will use rollstock or premade pouches. Then provide a drawing, specification, or physical sample for each format included in the quotation. A photograph helps with orientation, but it does not replace dimensions and material information.

For each SKU, record:

• Pouch style and finished orientation
• Width, length, gusset, and dimensional tolerances
• Target fill weight or volume and allowable headspace
• Film structure, total thickness, sealant layer, and supplier if already selected
• Zipper, spout, cap, valve, handle, tear notch, euro hole, or special shape
• Print registration and allowable print-to-cut or print-to-seal variation
• Seal appearance, seal width, leak requirement, and opening requirement
• Coding location and required variable information

If the material has not been finalized, say so. Ask the supplier to state which material assumptions were used for the quotation and what samples are needed before design approval. “Compatible with recyclable film” is not a complete requirement because different structures can have different stiffness, friction, sealing windows, and temperature sensitivity.

For a multi-SKU project, add a format matrix. Mark which sizes are required at launch, which are future options, and which only need a feasibility review. This prevents the base machine from being priced around an undefined future range.

3. Specify Output Without Using an Ambiguous Speed Number

“60 bags per minute” is incomplete unless the operating conditions are defined. Output can change with fill quantity, product behavior, pouch dimensions, sealing time, coding, inspection, operator loading, and upstream or downstream stops.

Write the production requirement in layers:

1. State the required accepted packs per minute for each priority SKU.
2. Define the product, fill quantity, pouch, and material used for that requirement.
3. State the planned shift pattern and required production volume.
4. Identify whether the figure is an instantaneous machine rate or a sustained test result.
5. Define whether rejects, planned stops, replenishment, and changeovers are included.

Ask each supplier to separate maximum mechanical rate, proposed running setpoint, and expected accepted output under the stated conditions. If a supplier cannot confirm the production figure until a sample test, the quotation should label it as subject to testing rather than present it as guaranteed performance.

4. Define Dosing, Quality, and Reject Criteria

The RFQ should explain what makes a finished pack acceptable. For filling, provide the target quantity and the permitted variation, plus the sampling and calculation method your quality team intends to use. Avoid requesting a single accuracy percentage without specifying product, dose, test duration, and measurement method.

Also identify the quality checks required in the proposed scope:

• Presence and position of product in the pack
• Fill-weight or volume verification
• Seal contamination, wrinkles, channels, or incomplete sealing
• Leak or seal-integrity inspection method
• Print registration and code legibility
• Pouch opening, zipper, spout, cap, or tear-feature function
• Metal detection, checkweighing, vision, or code verification
• Reject confirmation and reject-bin handling

Separate mandatory checks from optional checks. State whether inspection devices should be supplied by the machine builder, nominated by the buyer, or integrated as third-party equipment. The supplier should identify the interface and the party responsible for final line performance.

5. Map the Complete Line and Every Interface

A primary packaging machine rarely operates as an isolated asset. Provide a simple process flow from incoming product and empty packaging material to the discharge point. Include existing equipment that will remain in the line and new equipment that may be supplied by others.

For every interface, record:

• Upstream equipment and delivery method
• Product supply height, rate, buffer capacity, and control signal
• Downstream conveyor, inspection, cartoning, case packing, or collection method
• Infeed and discharge elevations and product orientation
• Required start, stop, ready, fault, starved, blocked, and emergency-stop behavior
• Data to be exchanged with line controls, production systems, or quality records
• Mechanical, electrical, software, and commissioning responsibility

If common machine states or production data are important to your plant, say so in the RFQ and describe the required interface. Do not assume that the word “integration” automatically includes programming, cables, guarding modifications, validation, or performance responsibility for equipment from multiple vendors.

6. Document the Installation Site and Utilities

Attach a dimensioned layout showing the available machine area, access routes, columns, drains, doors, ceiling height, operator aisles, and maintenance clearance. Include the space needed to bring the machine into the building and move major assemblies during service.

List the site conditions and available utilities:

• Country and installation address
• Power supply, frequency, voltage variation, and connection standard
• Compressed-air pressure, quality, and available flow
• Water, steam, vacuum, chilled water, extraction, or inert gas where relevant
• Ambient temperature, humidity, washdown, dust, and corrosion exposure
• Floor loading, anchoring restrictions, and drainage
• Required operator side and normal material-flow direction
• Noise, ventilation, and restricted-area requirements

Ask the supplier to return estimated consumption, connection points, heat load, exhaust needs, and final machine dimensions with the quotation or approved layout. This exposes facility work that may otherwise appear after the purchase order.

7. State Hygiene, Safety, and Market Requirements Precisely

Requirements depend on the product, cleaning method, destination market, and the way the machine will be used. State the country where the machine will be installed, the product-contact expectations, the sanitation procedure, and any internal engineering standards that the supplier must review.

Avoid vague lines such as “CE and food grade required.” Instead, ask the supplier to identify:

• The legislation, standards, and technical specifications applied to the proposed machine
• The scope and limits of any declaration or certificate
• Product-contact materials and supporting documentation
• Guarding, interlocks, emergency stops, and risk-assessment deliverables
• Electrical drawings, safety circuits, and control documentation
• Cleaning method, access, drainage, and removal of product-contact parts
• Documentation language and operator or maintenance instructions

Your engineering, safety, quality, and regulatory teams should approve the final requirement. The RFQ should not treat a certificate name as a substitute for reviewing the actual machine, application, documentation, and installation responsibilities.

8. Define Changeover, Cleaning, and Maintenance Expectations

List the SKU changes the machine must support and how often they occur. Identify which transitions are most important: small to large pouch, powder to powder, allergen to non-allergen, one spout size to another, or a film and print change.

Ask the supplier to describe:

• Parts, tools, settings, and recipes involved in each changeover
• Adjustment points and poka-yoke or verification features
• Product-contact parts that must be removed for cleaning
• Cleaning method and access to residue traps
• Routine inspection, lubrication, and preventive-maintenance tasks
• Recommended wear parts, commissioning spares, and critical spares
• Skills and estimated labor needed for normal maintenance

If changeover time is commercially important, define the start and end conditions and the operator resources used to measure it. A statement such as “quick changeover” cannot be compared or accepted without a test definition.

9. Make the Supply Scope and Deliverables Visible

Request a line-item scope rather than one total price with an equipment description. Every quotation should identify what is included, optional, excluded, or supplied by the buyer.

Request the commercial breakdown needed for your internal approval, which may include tooling, format parts, inspection systems, conveyors, guarding, software, documentation, packaging, freight basis, installation, commissioning, training, spares, and recurring licenses. Ask suppliers to state quotation validity, payment milestones, warranty terms, service assumptions, and items that require a separate quote. Do not assume these terms are standard across vendors.

10. Write Factory Acceptance Criteria Before Ordering

A factory acceptance test (FAT) is most useful when its protocol is discussed during quotation and finalized before the machine is complete. Otherwise, the test may become a demonstration chosen around whatever is easiest to run.

Define the proposed FAT inputs:

• Machine configuration and software version to be tested
• Buyer-approved product, packaging material, and priority SKU
• Quantity of test material and responsibility for shipping it
• Setup conditions and permitted pre-test adjustments
• Run duration and treatment of planned or unplanned stops
• Accepted-output target and reject classification
• Fill, seal, print, feature, and inspection sampling methods
• Alarm, interlock, guarding, power-recovery, and control checks
• Changeover or cleaning demonstration where included
• Required raw data, photographs, videos, and signed records
• Punch-list categories and rules for shipment approval

The supplier should state which tests can be completed at its factory and which require the installed line, production utilities, or downstream equipment. Site acceptance testing should cover the remaining site-dependent requirements. Keep the FAT and site acceptance responsibilities separate in the quotation.

Acceptance rule: A measurable criterion needs a defined product, package, operating condition, sample method, test duration, and pass rule. Without those elements, it is only an expectation.

A Copy-Ready Packaging Machine RFQ Structure

Use the following structure as the controlled document sent to every shortlisted supplier:

1. Project overview: business objective, current process, problem to solve, destination site, and required project timing.
2. Product data: product form, properties, variations, fill range, risks, and available samples.
3. Package data: rollstock or premade pouch, formats, dimensions, materials, features, printing, and samples.
4. Production requirements: priority SKUs, accepted output, shifts, annual or batch volume, changeover frequency, and quality criteria.
5. Required functions: feeding, dosing, forming or pouch handling, sealing, coding, inspection, rejection, and discharge.
6. Line integration: upstream and downstream equipment, elevations, control states, data, responsibility, and performance boundaries.
7. Site and utilities: layout, environment, access, power, air, services, and local engineering requirements.
8. Hygiene and safety: cleaning process, product-contact expectations, risk documentation, guarding, and destination-market requirements.
9. Supplier response format: proposed configuration, assumptions, deviations, options, exclusions, utility data, layout, and project responsibilities.
10. Project deliverables: drawings, manuals, software backup, spare-parts lists, training, installation, commissioning, and document language.
11. Acceptance plan: sample trial, FAT, site acceptance, evidence, punch-list process, and sign-off responsibility.
12. Commercial schedule: itemized price, commercial basis, payment milestones, quotation validity, lead-time definition, and warranty/service terms.

Issue the same revision to every supplier. Number each requirement so suppliers can respond with “complies,” “deviation,” “option,” or “not included” plus an explanation. Maintain a revision history when samples, formats, or targets change.

How to Compare the Quotations You Receive

Start with compliance and assumptions, not the total price. Build a comparison sheet with one row for every numbered RFQ requirement. Record the supplier response, evidence offered, deviation, option price, buyer-supplied item, and open question.

Then normalize each proposal across five levels:

1. Application fit: Does the proposal cover the actual product range, packages, accepted output, and quality method?
2. Scope completeness: Are filler, change parts, inspection, discharge, guarding, controls, and documentation included?
3. Integration boundary: Who owns each interface and who is responsible for the performance of the complete line?
4. Verification strength: Which claims are supported by sample testing, calculations, drawings, or agreed FAT criteria?
5. Lifecycle obligation: What operator time, utilities, maintenance, wear parts, support, and future-format work remain outside the purchase price?

A technically honest proposal may include more assumptions and open items than a short, confident quote. That is not automatically a weakness. Clear assumptions allow you to close gaps before contract award.

Common RFQ Mistakes to Avoid

• Asking for a price before defining the product and package
• Quoting one speed without an accepted-output test condition
• Sending a package photo without dimensions, tolerances, or material data
• Mixing launch SKUs with undefined future formats
• Assuming coding, inspection, conveyors, or line controls are included
• Using broad compliance terms without a destination market or document scope
• Leaving changeover, cleaning, and operator duties unmeasured
• Waiting until FAT to decide what successful performance means
• Comparing only purchase price instead of normalized project scope
• Allowing suppliers to answer different revisions of the requirement

Frequently Asked Questions

Should I choose a machine type before sending the RFQ?

Define the required packaging result first unless your plant has already approved a specific architecture for a documented reason. An outcome-based RFQ allows suppliers to propose premade-pouch, rollstock, horizontal, vertical, or filling-and-capping routes where relevant. You can then compare the trade-offs using the same product, package, output, site, and acceptance requirements.

What samples should I send to a packaging machine supplier?

Send representative product, packaging material, and finished-pack samples where practical. Include both normal and difficult variants if particle size, density, viscosity, pouch tolerance, film behavior, or another property changes. Label the sample revision and explain whether it is production material or a substitute.

How should I write a packaging machine speed requirement?

State accepted packs per minute for a defined product, dose, package, material, and operating condition. Also specify test duration, rejects, stops, and interfaces. Ask the supplier to separate maximum rate, proposed setpoint, and the result it is prepared to verify.

What should be included in a packaging machine FAT?

Include scope verification, drawings and documentation, safety functions, alarms, controls, product and package trials, accepted output, fill and seal checks, reject handling, and agreed changeover or cleaning demonstrations. Define the samples, methods, duration, evidence, and pass rules before the test.

How many suppliers should receive the RFQ?

The right number depends on project complexity and your sourcing policy. More quotations do not improve the decision if each supplier receives different inputs. Shortlist suppliers with a plausible technical fit, send the same controlled RFQ revision, and compare their assumptions and deviations line by line.

Can I request a quotation before my film or pouch is finalized?

Yes, but identify the packaging material as provisional. Provide the current structure, dimensions, and samples, then ask each supplier to list its assumptions and the validation work required before design release. Keep material-dependent speed, seal, and handling commitments conditional until representative samples are tested.

Prepare the Evidence Before You Request the Price

A strong packaging machine RFQ turns an application into a controlled set of requirements, responsibilities, and tests. Before requesting a proposal, organize your product data and samples, pack drawings and materials, priority output targets, quality rules, line interfaces, site utilities, required deliverables, and draft FAT criteria. With those inputs, a supplier can evaluate fit and return a quotation that your team can compare on scope and evidence rather than headline price alone.
