How do you use Crystal Discs to seal a mailing?

To seal a mailing with clear adhesive discs, you can follow these steps:

  1. Prepare Your Items: Make sure your items are ready to be placed inside the envelope or packaging. If you are sending multiple items, arrange them neatly.
  2. Place Items in the Envelope or Packaging: Put your items inside the envelope or packaging that you intend to mail. Ensure everything fits securely within the packaging.
  3. Close the Envelope or Packaging: Seal the envelope or packaging by folding the flap over the contents. Make sure it’s closed securely.
  4. Apply Clear Adhesive Discs: Take the clear adhesive discs and peel off the backing to expose the adhesive side. Place the adhesive disc over the sealed flap of the envelope or packaging. Press it down firmly to ensure a secure bond.
  5. Smooth Out the Adhesive Disc: Run your fingers over the clear adhesive disc to smooth out any air bubbles and ensure proper adhesion. This will help create a clean and professional-looking seal.
  6. Additional Discs if Necessary: Depending on the size and weight of your mailing, you may need to use additional clear adhesive discs. If the envelope is large or heavy, consider applying discs at multiple points for added reinforcement.
  7. Check for Security: Once the clear adhesive discs are applied, check to ensure that the envelope or packaging is securely sealed. Verify that the adhesive discs are holding the flap closed effectively.
  8. Label and Address: If you haven’t done so already, add the necessary labels and address information to the sealed envelope or packaging.

Clear adhesive discs that we sell as the brand Crystal Discs provide a secure and tamper-evident seal while also offering a professional and transparent finish. They are a convenient option for sealing mailings, especially when you want to maintain visibility of the contents or add an extra layer of security.
