I use “73mm fruit can ends” to describe metal can ends designed for fruit cans with a nominal 73 mm opening or body-end diameter, depending on the can system. The most important buying point is that 73 mm is not, by itself, a complete compatibility specification. Before placing an order, I verify the can body, end profile, countersink, compound, opening method, material, coating, and seaming requirements with the buyer’s can-making and filling equipment.

For most B2B buyers, the correct purchasing process is straightforward: confirm the dimensional drawing, match the end to the can body and seamer, define the fruit product and processing conditions, then approve samples or a technical specification before mass production. At Wanhua, I help customers organize these details so that the selected fruit can ends are evaluated as part of a complete packaging system rather than as an isolated metal component.
This guide is intended for fruit processors, canned-food manufacturers, packaging distributors, importers, and procurement teams sourcing 73mm can ends. It is also useful for engineering and quality teams that need to compare suppliers before approving a new packaging format. I focus on practical questions: what information to confirm, how to evaluate compatibility, and how to reduce avoidable sourcing risk.
The guide is especially relevant when a buyer is changing suppliers, launching a new fruit product, replacing an existing end, or purchasing ends for a contract packer. In each situation, the nominal diameter may appear familiar while other dimensions or performance requirements differ. A documented technical review is therefore more reliable than selecting a product from a size description alone.
A can end is the metal closure attached to a can body after filling. In fruit packaging, it helps provide a sealed container that can withstand handling, storage, transportation, and the intended thermal processing environment. Depending on the package design, the end may be used as a bottom end, a top end, or one of two ends with different opening functions.
The “73mm” designation normally refers to a nominal size used within a can-making system. It should not be treated as permission to mix components from different suppliers without dimensional verification. The actual outside dimensions, curl, countersink, panel, bead geometry, and compound application must correspond with the can body and seaming specifications.
Fruit can ends are commonly produced from coated steel or other metal constructions selected for strength, forming performance, and product-contact protection. The suitable substrate depends on the end design, can line, processing conditions, and customer requirements. I recommend asking the supplier to state the metal type, nominal thickness, coating system, coating side, and intended application instead of accepting a general description such as “food-grade metal.”
Internal coatings are particularly important because fruit products may contain water, acids, salts, sugars, or other ingredients that affect package interaction. The correct coating must be assessed against the actual product formula and processing method. If the fruit is packed in syrup, juice, or another liquid medium, I ask the buyer to provide the product profile so the coating discussion is based on use conditions rather than assumptions.
The nominal diameter is only the first specification. A complete drawing may also include the end height, countersink depth, curl dimensions, panel shape, bead configuration, compound weight, and tolerances. For a 73 mm format, I recommend that the buyer compare the supplier drawing with the existing can-body drawing before approving tooling or production.
The end can also differ by opening style. A conventional non-opening end may be appropriate where the can body is opened with a separate tool, while an easy-open end may be considered when consumer convenience is part of the package brief. Easy-open designs require additional review of score geometry, tab design, opening force targets, and line compatibility, so I do not treat them as interchangeable with standard ends.
| Specification area | What I recommend confirming | Why it matters |
|---|---|---|
| Nominal size | 73 mm format and the supplier’s exact drawing reference | Prevents size-only purchasing errors |
| Material | Metal type, thickness, temper, and coating system | Influences forming, strength, and product compatibility |
| Seaming geometry | Curl, countersink, panel, and specified tolerances | Must match the can body and seamer setup |
| Compound | Compound type, application location, and inspection method | Supports the intended seal and storage conditions |
| Decoration | Printing, varnish, color reference, and artwork requirements | Ensures appearance and brand consistency |
I match the end to four conditions: the can body, the seaming equipment, the food product, and the processing route. A fruit product packed under normal atmospheric conditions may have different requirements from a product exposed to retorting, pasteurization, or extended warehouse storage. The buyer should provide the filling and processing description before the supplier confirms the recommended construction.
Can-body compatibility is the first technical checkpoint. The end must fit the body diameter and flange geometry, while the complete package must be suitable for the customer’s seaming operation. Even when both components are described as 73 mm, differences in profile or tolerance can create sealing, feeding, or setup problems.

Product compatibility is the second checkpoint. I ask whether the product is acidic, syrup-based, salted, or otherwise chemically demanding, and whether it will be processed after seaming. The answer does not automatically determine one universal material or coating, but it gives the supplier the information needed to recommend a construction and define appropriate validation work.
Start with the product name, can-body specification, end type, nominal diameter, opening requirement, material preference, coating requirements, artwork, annual volume, and destination market. Include the seamer model or seaming parameters when available. I find that a clear requirement sheet reduces repeated questions and makes supplier quotations easier to compare.
Request a controlled technical drawing rather than relying only on a catalog title. I recommend checking 3–5 physical samples for visible defects, curl consistency, compound coverage, coating appearance, and fit with the intended body. Sample evaluation should be performed by the buyer’s packaging or quality team, because the supplier cannot independently confirm every condition on the customer’s line.
Agree in advance on the inspection items, sampling method, packaging condition, labeling, and nonconformance process. If the product will undergo thermal processing, the customer should define the relevant validation plan with its process and quality teams. A supplier can provide technical information and production samples, but final package approval belongs to the brand owner or processor responsible for the filled product.
Compare price together with minimum order quantity, tooling, artwork setup, packaging, delivery terms, payment terms, and replacement policy. A lower unit price may not be economical if the order quantity is too high, the lead time does not match the filling schedule, or the packaging format creates additional handling work. I recommend requesting the same information from each shortlisted supplier so the comparison is consistent.
Pricing for 73mm fruit can ends depends on metal cost, thickness, coating, printing, end design, order volume, packaging, and production planning. Because these variables change by project, I do not present a universal price or MOQ as if it applied to every buyer. Instead, I prepare a quotation after confirming the technical specification and estimated demand.
Lead time should be separated into artwork approval, tooling or setup, sample approval, production, and shipment. Buyers should ask whether the quoted lead time starts from purchase-order receipt, drawing approval, or deposit payment. For seasonal fruit products, I recommend planning across at least 2–3 production lots or delivery windows where possible, because a single late shipment can affect filling schedules and inventory control.
When I evaluate a 73mm fruit can end supplier, I look for technical clarity, consistent communication, and the ability to connect the end specification with the customer’s can system. I also check whether the supplier can explain material, coating, compound, inspection, packaging, and traceability arrangements without making unsupported claims. A professional response should identify what is confirmed, what requires samples, and what must be validated by the buyer.
At Wanhua, I approach 73mm fruit can ends as a B2B packaging project requiring technical and commercial coordination. Our discussion can cover the requested size, end type, material direction, coating needs, printing or decoration, packaging method, and export requirements. When the application information is incomplete, I prefer to identify the missing data first rather than offer an overconfident recommendation.
We can support supplier communication by reviewing drawings, organizing sample requirements, clarifying quotation conditions, and aligning production details with the buyer’s purchasing schedule. The final specification should be confirmed jointly with the customer’s packaging, quality, and production teams. This process helps establish a clear basis for repeat purchasing and reduces the risk of ordering a nominally similar but technically unsuitable end.
The right 73mm fruit can end is defined by more than its nominal diameter. I recommend confirming the complete drawing, material and coating, compound, opening style, can-body match, seamer compatibility, product conditions, processing route, and commercial terms before purchase. Samples should be reviewed against agreed criteria, with final approval based on the customer’s actual packaging system.
To begin a supplier discussion with Wanhua, prepare the 73mm requirement, can-body drawing, product description, processing information, estimated quantity, artwork needs, and target delivery schedule. I can then help structure the technical questions and identify which details require sample or line validation. This is the most practical route to selecting a compatible end and building a reliable fruit-can supply plan.
