A clamshell’s stated wax capacity tells you little about the available label panel. The hinge, cavities, hang tab and front contours all influence the printed area. Compare actual empty packages before choosing one layout for your wax melt range.
01
Measure the closed pack rather than a single cavity
Put the empty clamshell into its closed retail position. Measure its complete height and width, then mark any raised areas, ribs and recessed panels on a paper outline. Keep the hanging tab as a separate part of the measurement record.
Suppliers offer different cavity arrangements, including multi-piece packs and snap bars. Their stated fill and cavity measurements serve a different purpose from your label plan. Read the supplier’s drawing and check a sample of the exact model before ordering printed labels.
02
Locate the uninterrupted print surface
Hold a paper front label against the closed pack. Leave the hinge, opening lip and hanging hole free of essential text. If the flat area narrows near the top, a simple rectangle may need to stop below that point or become a smaller face label.
For an illustrative model with a 65 × 90 mm flat panel, compare two paper labels that fit inside it with different margins. Check the longer scent name on both proofs. Use the same type size initially so the comparison shows the available breathing room rather than an unrelated typography change.
| Pack feature | Separate measurement |
|---|---|
| Closed outline | Retail footprint and display fit. |
| Flat label panel | Usable artwork area. |
| Hang tab | Hole and hardware clearance. |
| Opening lip | Space for the customer to grip. |
03
Test the intended display
Hang a complete labelled sample on the actual hook, or set it upright in a tray. Look at it beside neighboring packs. A tab that clears the hook on its own can become awkward when several products overlap.
Check which words remain visible when the next pack sits in front. If the shelf displays only the upper part of the label, move the scent identification into that view or use a coordinated second identifier that suits the package. Keep the product name clear even when the fill is hidden.
04
Tie the file to the clamshell model
Store the print file with the supplier’s model code and a photo of the closed sample. A six-piece pack and a similar-looking pack from another supplier can have different edges and hinge positions. Review the outline before reusing artwork.
When adding a seasonal scent, use the same proof routine on the longest name. Keep the product-specific directions with the package. Ask the printer about stock and adhesive suitable for the chosen plastic and its expected handling.
BEFORE YOUR NEXT STEP
Your practical checklist
- Measure the closed clamshell.
- Separate the hang tab from the label panel.
- Try the sample in its display.
- Record the exact supplier model.
Questions & answers
Does the wax capacity determine label size?+
Use the physical dimensions of the clamshell. Capacity and cavity measurements do not establish the flat label panel.
Can I cover the hanging tab with a label?+
Keep the hanging hole and the area needed by the display hardware clear. Test a physical sample on the actual hook.
