A 73mm fruit can end is a metal closure designed to fit a can body with a matching end specification; the “73mm” designation alone does not confirm that it will run on your line or form a reliable seam. Before purchasing, compare the end drawing and profile with your can body, seaming equipment, product process, and opening requirements. At Wanhua, we recommend confirming these details with both your can supplier and end supplier before approving production. This guide explains what to check and what information to prepare for a supplier enquiry.
Use 73mm as a nominal size reference, not as a complete compatibility specification. The end profile, curl, countersink, compound, and body dimensions also matter.
Match the end to the can body and seamer using approved drawings and trial results, rather than relying on diameter alone.
Share product, processing, line, and annual-volume information with suppliers so they can assess the correct construction and sourcing plan.
Request technical documents, samples, and a clear confirmation of tooling and production compatibility before placing a volume order.
This guide is intended for food-packaging buyers, can makers, fruit processors, importers, and packaging engineers evaluating 73mm fruit can ends. It is useful when sourcing a replacement end, planning a new can format, or checking whether a proposed closure will work with existing equipment. It can also help purchasing teams prepare a more complete request for quotation. Final compatibility should be confirmed against the actual can and seaming system.
The term describes a can end associated with a nominal 73 mm diameter for fruit packaging. As a unit conversion, 73 mm equals 7.3 cm, or approximately 2.87 inches. These conversions describe the nominal designation only; they do not specify the full end geometry or the dimensions of a finished can.
A can end closes the open end of a can body and forms part of the package’s barrier to the outside environment. Depending on the can design, an end may serve as a bottom closure, a top closure, or an opening end. Buyers should state which position and end style they need because the same nominal diameter does not mean that different designs are interchangeable.
A plain end is generally opened with a separate tool, while an easy-open end includes a designed opening feature, such as a tab and scored panel. The choice affects consumer access, end construction, and compatibility with the can and seaming process. Specify the opening style explicitly rather than assuming a supplier will infer it from “fruit can end.”
Start with the supplier’s technical drawing and compare it with the can body drawing. Important details may include the end’s outside dimensions, curl profile, countersink, panel configuration, and the geometry required to form the double seam. Ask the supplier to identify the drawing revision and confirm which dimensions are controlled for your application.
Ends may be made from metal packaging substrates such as tinplate or other coated steel, depending on the design and supply specification. The correct material and coating system depend on the product, storage conditions, processing method, and contact requirements. Do not select a material based only on appearance or a general description; request the relevant material and coating details for review.
Fruit products can vary in acidity, ingredients, and processing conditions, so coating suitability should be assessed for the specific product and process. Share the product type and any known interaction or corrosion requirements with the supplier. Where a coating or internal lacquer is specified, confirm its application area and suitability with the packaging and food-safety teams responsible for the product.
The sealing compound applied to an end contributes to the closure formed during seaming. Its specification and application must suit the can body, end profile, seamer setup, and process requirements. Ask whether the offered end uses the compound type and application arrangement required by your can system, and validate the resulting seam under your operating conditions.
Compatibility is a system question: the can end, can body, seaming rolls, chuck, and seamer settings must work together. A nominal diameter match is a useful starting point, but it cannot replace a drawing review or production validation. Use the following steps to structure your evaluation.
Define the package. Identify whether the 73mm end is for the top or bottom, the required opening style, the can-body material, and the intended finished-can dimensions. Include the body maker or current end specification if available.
Describe the product and process. Tell the supplier what fruit product will be packed and provide relevant filling, closing, thermal-processing, and storage conditions. Do not assume that an end approved for one recipe or process will automatically suit another.
Share equipment details. Provide the seamer model or relevant tooling information, current end drawing, and target production rate in cans per minute. Ask your equipment or can supplier to confirm the required chuck, roll, and seam parameters.

Review documentation and samples. Compare the proposed drawing with your approved package specification, then arrange samples or a controlled trial if appropriate. Record any agreed changes and the acceptance criteria before moving to production quantities.
Confirm commercial requirements. State estimated annual demand in ends per year, delivery destination, packaging requirements, and target schedule. These details help suppliers evaluate production planning and quotation scope.
Ask the supplier to confirm in writing which can-body specification and end profile the quotation covers. Request the applicable drawing, material information, and inspection or quality documentation available for the product. Determine how changes to dimensions, coating, compound, or tooling will be reviewed and approved.
Price comparisons are meaningful only when the quoted specifications, packing method, order quantity, and delivery terms are comparable. Minimum order quantities and lead times can vary by supplier, material availability, tooling status, and production schedule, so request current values rather than relying on general estimates. Clarify whether the quote includes tooling or setup charges, sample costs, export packing, and any other applicable fees.
For planning, provide both an initial order quantity and a realistic annual forecast. Ask the supplier to state the assumed production and shipping schedule, and identify which events could affect it, such as drawing approval or trial completion. This makes it easier to compare offers on total supply fit instead of unit price alone.
Can the supplier provide a current technical drawing and explain the relevant dimensions?
Will the supplier confirm the proposed end against your can-body and seamer information?
Are material, coating, compound, and opening-style details stated clearly in the offer?
Are MOQ, lead time, packaging, delivery terms, and quotation assumptions documented?
Can the supplier support sample review, technical questions, and change-control communication?
The most common risk is treating 73mm as a complete product specification. Buyers can also overlook differences between top and bottom ends, assume that a familiar end will suit a different can body, or omit processing details when asking for a quotation. Another avoidable issue is approving samples without documenting the specification and trial conditions they represent.
Reduce these risks by keeping one approved drawing and specification for each package configuration. Involve packaging, production, quality, and procurement stakeholders before final approval. If a supplier proposes a substitution, review the changed material or geometry and repeat the necessary validation rather than assuming the change is equivalent.
At Wanhua, we can discuss your 73mm fruit can end requirements as a manufacturer, supplier, and exporter in packaging and printing. To make an enquiry actionable, send your end and can-body drawings, intended use, opening style, seamer details, target quantity, and destination market. We can then review the requested specification and clarify which product, documentation, samples, and commercial details are available for your project.
Where a drawing or equipment detail is missing, we recommend identifying that gap before quotation approval. Our team can coordinate technical questions with you so the proposed end is assessed against the package information you provide. Any final production decision should follow drawing approval and the validation steps required by your own packaging and process controls.
A 73mm fruit can end is suitable only when its full specification matches the can body, seaming equipment, product, and processing conditions. The nominal size—73 mm, approximately 2.87 inches—is a starting reference, not proof of interchangeability. The practical next step is to assemble your drawings, process details, equipment information, volume forecast, and delivery requirements for supplier review.
Contact Wanhua with those details to discuss specification review, samples, and a quotation for your project. Confirm the approved drawing and trial requirements before committing to production quantities. This approach gives your team a clearer basis for evaluating compatibility, supply terms, and the right 73mm end for your fruit can format.
