Changing coffee packaging suppliers works best as a controlled handover. Start by documenting the pack you need, the process it must fit and the evidence used to approve it. Then compare the proposed replacement against that brief. Matching a photograph, a nominal weight or a general material name is not enough to establish equivalence. The new supplier needs a clear route from reference pack to written specification, trial and approval.
Define the reason for the change
Write down the problem or opportunity being addressed: a different format, production support, artwork consistency, sourcing flexibility or another specific requirement. Describe the current result and the desired result without inventing a performance target from a competitor’s marketing. A clear reason helps the supplier identify which aspects of the existing pack must be preserved and which can be reconsidered.
Separate a commercial comparison from a technical substitution. A different quotation may reflect another quantity, print route, finish or delivery scope. Establish the common requirements first, then evaluate the proposed differences. This creates a useful conversation about the project rather than an attempt to reproduce an unknown pack at an arbitrary price.
Build the handover file
Provide the current finished dimensions, material information available, selected features, artwork and filling details. Include representative physical samples when possible. Mark information that is unknown rather than assigning a laminate from appearance. A foil-looking layer, a kraft-facing surface or a valve visible in a photograph does not identify the complete package.
Confirm that the artwork and any supplied production files can be used for the new project. Ask which editable artwork, dielines or references are needed. Keep ownership and permitted use clear with the relevant parties. A physical bag can guide a discussion, but it is not a replacement for authorised, production-ready artwork.
| Handover item | Useful information | Question to resolve |
|---|---|---|
| Current pack | Dimensions, features and representative sample | Which version and use does it represent? |
| Coffee and filling | Product state, dose, opening and equipment | What must the new pack physically fit? |
| Artwork | Editable files, codes and existing dieline | What needs a new production layout? |
| Acceptance | Agreed fit, print and quality review points | What evidence permits release? |
Treat the dieline as a new production decision
A new supplier may use a different converting route or require different working areas. Ask for the project dieline before treating old artwork as ready for production. Review panel order, folds, seals, zipper or fitment clearances and the print-safe area. Preserve the intended brand hierarchy while adapting the file to the confirmed construction.
Compare the old and proposed filled presentation, not only two flat drawings. Check the coffee identity, information positions and how artwork crosses corners or gussets. Use the dieline checklist to record the decisions. A matching outer dimension does not guarantee that every printed element occupies the same usable panel.
Compare samples with the actual product
Use the intended roast or grind and net weight where fill affects the result. For a flexible coffee bag, review the opening, headspace, selected closure and filled stance. For containers, single-serve components or liquid formats, agree the relevant assembly, brewing or equipment review rather than applying the same bag checklist to every product.
Document the sample construction and the question it answers. A stock sample can be a useful starting reference, but it does not establish every detail of the proposed custom project. Use the sample approval guide to distinguish the physical reference, artwork proof and production release.
Agree the evidence before comparing results
List the performance questions that matter to the actual product and distribution route. Confirm the relevant test methods, conditions and acceptance criteria with the responsible parties. Compare results only when the sample and conditions are sufficiently aligned. A barrier figure without its units and conditions, or a certificate that applies to another structure, leaves an important gap.
If the project involves environmental or food-contact statements, ask what documentation applies to the complete proposed pack and destination. Do not transfer a claim from the previous supplier by copying its label. This is a scope question for the selected construction and market, not a conclusion that can be drawn from a similar-looking material.
Plan the transition stock
Map the current stock, expected use by SKU and the timing needed to qualify the new pack. Keep the planned first order separate from an assumed full conversion of the range. The project may need staged approvals when sizes, designs or filling routes differ. Agree which version will be used during the transition and how the packing team distinguishes it.
Treat timing as a confirmed project input. Artwork completion, sample review, production release and shipment are separate milestones. Record who owns each next action and what must be approved before it proceeds. Avoid a plan that consumes the existing stock before the replacement packaging has answered the agreed questions.
Make the first order a controlled reference
Release the first production order against the agreed specification, artwork and acceptance record. Retain the accepted reference and document any deviations or approved changes. This creates a clear basis for repeat orders and prevents an informal adjustment during the transition from becoming an undocumented permanent change.
Share the coffee application, target format, quantity per design, destination and the information already available in a packaging brief. Crystavo can review the sourcing project without assuming that the existing bag is a complete specification. The purpose of the handover is a repeatable approved pack, with the important decisions made visible.
In practice
Transfer the specification, not assumptions.
A new supplier needs a reproducible brief and a clear approval route.
Build a transition pack
Gather the approved dimensions, material description, selected features, artwork ownership information and relevant trial records. Include a physical reference where available and identify which aspects must remain consistent. Separate the desired appearance from requirements supported by evidence.
Do not assume a new supplier can infer every layer or tolerance from an empty bag. Ask it to identify any proposed differences explicitly so the team can decide whether another sample, proof or filling trial is needed.
Avoid a rushed changeover
Count remaining usable bags and identify the last date a new order can arrive without disrupting packing. Allow time for the new reference to be reviewed before the old supply is exhausted. Keep the outgoing and incoming versions labeled separately during the transition, especially if they look similar.
Agree how first-delivery observations will be recorded and who can approve a change. A successful transition means the purchasing, design, filling and receiving teams all know which specification is current.
