To select a compatible food or beverage can bottom end, match its dimensions and seaming profile to the can body, seamer, filling process, and product conditions. A diameter code alone is not enough: buyers should confirm the end’s material, thickness, coating, curl, countersink, sealing compound, and performance requirements with the can or end manufacturer. We recommend sharing the can-body and equipment specifications before requesting samples or a quotation. This guide explains what to check and how to make a more complete purchasing decision.

This guide is for food and beverage can manufacturers, fillers, packaging buyers, and product teams evaluating bottom ends for a new project or a change in supply. It is also useful when a line experiences fit or seaming issues, or when a buyer needs to compare supplier quotations on a like-for-like basis. Requirements can differ between can formats and production lines, so the final specification should be agreed by the relevant packaging and equipment teams. We use “bottom end” to mean the closure attached to the base of a can body.
A bottom end closes the lower opening of the can body and forms part of the package’s structural barrier. It must be compatible with the body’s flange and the seaming operation so that the assembled package can meet its intended use. Depending on the pack design, the end may also need to tolerate filling, handling, storage, and thermal processing conditions. The end is therefore a component of a packaging system, not a standalone part selected by diameter alone.
Food and beverage cans may use ends made from steel or aluminum, depending on the overall package design and the materials selected for the can body. The appropriate option depends on the can format, production equipment, product requirements, and the buyer’s material and sourcing criteria. Some ends are plain or non-opening closures, while other can formats use opening features; the correct design depends on the package specification. Confirm the exact end style with your can manufacturer and seamer supplier rather than assuming that visually similar ends are interchangeable.
Applications can include canned foods, drinks, and other products packed in metal cans. Their processing and storage conditions are not identical. For example, a package intended for retort processing may have different requirements from one intended for a beverage filling line. Tell the supplier what the package must withstand and ask whether the proposed end design is intended for those conditions.
Start with the can-body drawing and the end specification used by the production line. Confirm the nominal diameter, but also check the dimensions and profile that affect how the end and body form a double seam. Relevant details may include the end curl, countersink, flange, and other interface dimensions. Your seamer setup and tooling are part of this compatibility check, so involve the equipment or packaging engineer where possible.
With competitive price and timely delivery, Wanhua sincerely hope to be your supplier and partner.
To make the units in an RFQ unambiguous, use an example format such as “nominal diameter: 73 mm; sheet thickness: 0.20 mm; coating weight: 6 g/m².” These figures are illustrative placeholders only, not standard values or product recommendations. Replace them with values from your approved design, drawing, or engineering review. If a measurement method or tolerance matters, specify it in the same document.
Define the product, can format, filling method, and any thermal or pressure conditions before comparing options. Share these details with the end supplier because application conditions can affect material and coating selection. If the package or process is changing, treat compatibility as a new review rather than relying solely on a previous approval. The can maker, filler, and equipment provider may all need to contribute to the final decision.
Ask each supplier to quote against the same drawing revision and specification. Compare the quoted material and thickness, coating and compound details, quality documentation, packaging, delivery terms, and any tooling or sample charges. Clarify minimum order quantity (MOQ), production lead time, payment terms, and how changes to the specification are handled. A low unit price is difficult to evaluate fairly if the quoted scope or delivery assumptions differ.
MOQ and lead time can vary with the end design, order quantity, available materials, production planning, and destination. Request the supplier’s current terms rather than relying on a general estimate. For a new design, ask whether samples or a trial order are available and how that work affects the schedule. Include your required delivery date and forecast in the enquiry so the supplier can assess the request against its production plan.
As a packaging and printing supplier, Wanhua can discuss Food And Beverage Can Bottom Ends in relation to your project requirements and help clarify the specification information needed for a quotation. Share the size designation, drawings, application, target quantity, and destination with our team. We can then review the enquiry scope and confirm the next steps, including whether samples or additional technical details are needed. Final suitability should be verified against your can body, production equipment, and applicable product requirements.
The right food or beverage can bottom end is the one whose dimensions, material, coating, compound, and seaming profile have been checked against your can body, equipment, product, and process. Begin with a current drawing and complete application details, then request a supplier review and validate samples on the intended line. Before ordering, agree the controlled specification, quality criteria, MOQ, lead time, and delivery terms in writing. Contact Wanhua with your project details to start a B2B enquiry and determine the information needed for a suitable quotation.
