A new bottled product can involve several teams working at once. Marketing is finalising the label, purchasing is comparing suppliers, and production is preparing for the first trial.

The small foil seal beneath the cap can easily become a late-stage decision.

Preparing its requirements early gives everyone a clearer basis for quotation, sampling, and approval. It also helps suppliers understand what they are being asked to deliver.

Provide the Bottle and Cap Specifications

Begin with the bottle material, opening dimensions, neck drawing, and cap details.

If drawings are unavailable, clear photographs and physical samples can help start the conversation. An existing liner sample is also useful when sourcing a replacement.

Avoid relying only on a description such as “a 38 mm bottle liner.” The nominal size does not explain the complete application.

Explain the Product and Sealing Process

Tell the supplier what the bottle will contain, how it will be filled, and how it will be stored.

Provide the sealing equipment type and relevant operating information if available. For a new production line, identify which details are still being confirmed so the sample plan can account for them.

Clarify Custom Printing Requirements

If the liner needs a logo or opening message, supply the proposed artwork and explain how it should appear on the finished seal.

Discuss print layout and orientation requirements with the supplier before approving the design. Request an artwork proof so wording and graphics can be checked before production.

Custom printing requirements should be considered alongside the liner structure and sealing application.

Break Down the Order Quantity

Provide the estimated quantity for each size and printed design, rather than only a combined total.

Also distinguish between an initial trial order and expected repeat demand. This helps the supplier prepare a quotation based on the actual purchasing plan.

Ask for confirmation of minimum order quantities, sampling costs, production lead time, and any applicable tooling or printing setup charges.

Agree on How Samples Will Be Approved

Define what needs to be checked before a bulk order is released. Depending on the application, this may include fit, sealing performance, opening behaviour, and printed appearance.

Record the approved specification and sample reference so purchasing, production, and the supplier work from the same information.
