About Opaque/Blockout
Opaque/blockout labels from LabelsOnline.com are designed specifically for applications where a label must completely conceal what’s printed underneath — making them the go-to choice for price tag cover-ups, relabeling, barcode correction, confidential information blocking, and any situation where an existing label or printed text must be permanently hidden. The opaque white face stock blocks light transmission entirely, preventing the original print from showing through under normal or backlit viewing.
Compatible with both laser and inkjet printers. Available in 150+ sizes and shapes on standard 8.5" x 11" sheets. All labels use permanent adhesive. US-made and backed by our 100% satisfaction guarantee.
Frequently Asked Questions
Will opaque/blockout labels hide barcodes and text printed on boxes?
Yes — opaque/blockout labels are specifically engineered to block through-light transmission and conceal what’s underneath. They are widely used to cover outdated barcodes on cartons, conceal old price tags on merchandise, block out confidential information before disposal, and correct label errors on already-packed inventory. The full opacity ensures the original content is not readable through the label under any normal lighting.
Can I use opaque labels over existing labels on a box?
Yes — opaque/blockout labels can be applied directly over existing labels on corrugated boxes, cartons, or flat surfaces. The blockout adhesive holds securely over most existing label stock. For particularly rough corrugated surfaces, consider pairing with our aggressive adhesive opaque labels for maximum bond.
