Blockout Label Uses & Features

Most standard label materials aren't opaque enough to entirely block out underlying text and images. Our blockout labels utilize an opaque coating on the back of the label material instead of a standard clear or white one. This creates a solid barrier, preventing light from passing through the label. From the top, they're a standard, bright white label that will help colors pop, scanners read barcodes, and products fly off the shelves.

These permanent cover-up labels are perfect for the following applications:

  • Covering up shipping information on boxes
  • Making use of old tubes and packaging
  • Blocking out old shipping labels
  • Concealing outdated information
  • Masking printing mistakes
  • Fixing grammatical errors and typos
  • Safeguarding confidential information
  • Updating barcodes and QR codes
  • Adjusting pricing

Frequently Asked Questions

  • What are blockout labels used for?

    Blockout labels are used to cover existing text, barcodes, pricing, graphics, or old label information. They’re helpful for relabeling packaging, correcting printed materials, reusing boxes, updating inventory, or covering outdated branding. The goal is to keep the original information from showing through the new label.

  • When should I choose blockout labels instead of standard white labels?

    Choose blockout labels when the information underneath should not show through. Standard white labels may be enough for blank or lightly colored surfaces, but they may not fully hide dark print, barcodes, or graphics. Blockout labels are a better choice when coverage is part of the job.

  • Are blockout labels good for inventory and warehouse updates?

    Yes, blockout labels can help update inventory IDs, barcodes, shipping information, and warehouse markings. They’re useful when products, cartons, or shelves need new information without replacing the original surface.

  • Can I print on blockout labels?

    Yes, blockout labels are compatible with inkjet and laser printers. They can be printed with updated barcodes, product information, pricing, addresses, or correction details. Use them when you need to cover existing text or graphics and replace them with new label information.

  • Will the old label show through?

    Blockout labels are designed to help cover existing print, graphics, or barcodes. For the cleanest result, choose a label size that fully covers the old information. Test first if the original print is very dark, textured, or close to the label edge.
