Plan the Opening Path for a Perforated Circle Seal
Evaluate a perforated circle seal with the opening motion of the finished package. Its diameter tells you the size of the circle. It does not show where the perforation lies on the sample or how the recipient should open the sealed flap.
Choose placement by examining the actual label and package together. A seal intended to help opening serves a different purpose from a round color cue used for sorting or inventory.
Start with the exact perforated label
DL703 clear perforated circle mailing labels are listed as 1-inch-diameter polystyrene circles, with 5,000 labels per roll. The description identifies perforated edges for opening on envelopes and small boxes.
Check the supplied label before designing an opening instruction. Do not assume it has a straight perforation through its center or that the roll's separation points define the label's own opening feature.
Compare possible placements on a sample
In a hypothetical folded-card package, the circle bridges the closing flap and the supporting face. The recipient should open that flap while keeping the printed content readable.
| What to inspect | Why it matters to the opening decision |
|---|---|
| Actual perforation on the detached label | Confirms the opening feature being positioned |
| Label contact on flap and supporting face | Shows how the seal connects the two surfaces |
| Printed content beneath and beside the seal | Shows what remains visible and what the opening may disturb |
| Recipient's opening motion | Shows whether the intended action works with that placement |
Trial the intended position and an alternative if needed. Observe the actual opening result rather than treating a transparent label as invisible to the handling process.
Keep the material trial specific
Use the same paper, coating and flap arrangement planned for production. Apply the label according to the applicable product instructions, then open the sample as a recipient would. Inspect the label and both package surfaces against the desired result.
If the flap opens somewhere other than intended, change the placement or packaging method and trial again. The product's perforated designation does not guarantee the same result on every carton finish or envelope stock.
Write the instruction after the trial
Show the opening point in a sample photograph or a clear instruction only after it has been verified on the finished arrangement. Avoid telling recipients to cut or tear through a location that the actual sample does not support.
Keep the selected SKU, substrate, placement and approved opening result together for reorders. This guide does not establish a postal acceptance rule or a security certification for the finished mail piece.
Use the circle mailing label guide to distinguish round visual markers from the sealing function considered here. Select DL703 because its documented perforated format matches the opening trial, not merely because another circle label shares its diameter.
