Why choose Go2Products?
Rated Excellent by our customers
Opaque Paper Blockout Labels with an integrated black backing and a strong permanent adhesive. Supplied on A4 sheets, designed to completely cover existing text, graphics, colours and barcodes — nothing shows through (guaranteed).
Made to order lead times:
Blank and printed opaque blockout labels are dispatched within 3 working days.
Non-returnable: These sheets are made to order and are non-returnable unless faulty. If you’d like to check suitability first, we’re happy to supply a sample.
These blockout labels are ideal when you need a fast, clean cover-up solution without wasting packaging or reprinting stock. They are suitable for laser and inkjet printers, photocopying, and handwriting. Great for everyday business relabelling across offices, warehouses, retail, fulfilment and manufacturing. If you don't need the opaque black backing, explore our blank A4 labels for our wider range of standard label materials.
Guaranteed opacity (blockout)
The integrated black backing prevents show-through, even over bold print, logos and barcodes. Ideal for correcting errors, replacing outdated information, or reusing packaging and envelopes.
Colour & finish
Matt white paper face stock for a clean professional finish, with a black backing for full coverage. Designed for sharp print results and easy readability.
Looking for a more natural finish rather than a cover-up material? Our brown kraft paper labels provide a distinctive rustic appearance for product packaging, jars, boxes and other branding applications.
All label sizes are available within this product — simply choose your size above. If you can't find the exact size or specification you need, explore our labels made to order for additional sizes, shapes and specialist material options.
Need opaque labels on rolls?
Need an opaque or blockout label supplied on rolls rather than A4 sheets? We can produce specialist roll label specifications for commercial and higher-volume applications. Tell us the size, quantity and application using our label quote form and our team will advise on the best option.

Opaque blockout labels are designed for cover-up, corrections and updates where reprinting would be costly or wasteful. Common uses include:
Covering up mistakes
Cover printing errors on labels, packaging, envelopes, documents and forms. Apply a corrected label over the mistake — quicker, cheaper and easier than reprinting entire batches.
Out of date information
Replace old pricing, addresses, ingredients, product info, batch codes, expiry dates, compliance text, warning labels, or SKU/barcode data without binning usable stock.
Recycling packaging & envelopes
Cover old shipping labels, branding or address details so cartons, boxes and envelopes can be reused. Great for e-commerce, fulfilment, returns handling and internal distribution.
Warehouse & logistics updates
Update location labels, pallet labels, pick-face labels, stock ID labels, shelf labels and dispatch identifiers. Useful where products move fast and label data changes frequently.
Retail & price changes
Ideal for repricing, promotions, clearance changes, product relabelling and barcode updates without damaging packaging.
Office & admin relabelling
Cover old file labels, archive box labels, folder spines, internal mail labels, asset labels and document identifiers.
Returns / refurb / rework
Cover original labels on returned items, reboxed goods or reworked stock — replace with updated SKU, condition, or routing information.

What are blockout labels?
Blockout labels are opaque cover-up labels designed to hide existing text, images, colours and barcodes underneath, so you can relabel quickly and cleanly.
Do these labels completely cover what’s underneath?
Yes. They have an integrated black backing that provides guaranteed opacity — nothing shows through.
Can anything be seen behind the label?
No. Underlying text, graphics, barcodes and colours are fully blocked out.
Which printers are these sheets compatible with?
These A4 sheets are suitable for laser and inkjet printers. They’re also suitable for photocopying and handwriting.
Are these labels waterproof?
These are paper blockout labels, so they are not intended as a waterproof label. If you need a waterproof, opaque or specialist film material, please request a quote and we'll recommend the most suitable option for your application.
What adhesive do these labels use?
They use a strong permanent adhesive designed for reliable long-term sticking on typical packaging and labelling surfaces.
What surfaces do they stick to?
They work best on clean, dry, smooth surfaces like cartons, packaging, envelopes, boxes, folders, and many retail packs. For dusty, textured, or heavily curved items, we recommend testing a sample first.
What are these labels commonly used for?
Covering up mistakes, replacing out-of-date information, reusing packaging and envelopes, updating barcodes/SKUs, warehouse relabelling, repricing, and office/admin identification.
Can you print these blockout labels for us?
Yes. Choose blank sheets or order printed labels (we can print your supplied artwork).
How long does dispatch take?
Made to order:
Blank sheets (black backing): dispatch in 24–48 hours.
Printed labels: dispatch in 3–5 working days.
Can I return these sheets?
These sheets are non-returnable because they are made to order (unless faulty). If you’d like to check suitability first, request a sample.
