How to Choose a Fruit Clamshell Size

Start with the fruit, not a weight label

Measure representative fruit, including the largest pieces, and note the planned fill weight and packing orientation. A 125 g or 250 g label does not identify one universal box size. Fruit shape and how it settles affect the space required; confirm the intended fill with your own produce.

Compare actual model dimensions

HC-250 and HC-500B are two clear PET clamshells in HongPack’s small–medium fruit series. The dimensions below come from the product catalogue and identify the outside footprint and height. The model code is not a guaranteed fruit-weight capacity. Open a model to review its recorded weight options and carton packing, or request a quote for that exact model.

Check usable space and lid clearance

Outside length, width and height are useful for a shortlist, but they do not describe the usable cavity. Tapered walls, ribs and the lid shape can reduce clearance. Fill a sample to your target level, close it without forcing the lid and check for fruit compression, excessive movement and interference with the closure. Do not calculate a guaranteed capacity by multiplying outside dimensions.

Review ventilation, handling and labels

Check the selected model’s vents, drainage, closure and label area against your packing and cooling process. A pack that fits the fruit must also suit filling, shelf display and transport. Confirm these details for the actual model and sample; a photo alone does not establish airflow, protection or shelf life.

Test filled packs in the shipping carton

Use the intended carton’s inside dimensions to check pack orientation, packs per layer and loaded stack height. Check that closures stay engaged and that stacked packs do not press on the fruit. Distinguish empty containers per shipping carton from filled retail packs per produce carton; they are different packing counts. Confirm the exact product weight option and empty-pack packing arrangement with the quotation.

Record the sample trial before ordering

For each candidate, note the model, fruit type and size, actual fill weight, lid clearance, closure result, filled packs per carton and handling observations. Test with the conditions relevant to your supply chain. Keep the approved sample and agreed packing specification as the reference for the order. Existing-mould samples are free; confirm availability, destination and courier arrangements before dispatch.

Send a short sizing or quotation request

You only need your email and a short requirement to begin. Include the model if known, fruit type, target fill weight, estimated order quantity and destination. A current-pack photo or carton inside dimensions can help us narrow the options; send photos or drawings by email afterwards. If neither example fits, ask us to review another existing model or a custom size.
