Sheet Labels
139 x 99.1mm No.4 White Self-Adhesive Sheet Labels (100 Sheets/Box) — Product Overview
These No.4 white self-adhesive sheet labels are supplied on convenient A4 sheets and are designed for clear, professional labelling across a wide range of workplace and dispatch tasks. With a generous label face (139 x 99.1mm), they provide ample space for addresses, barcodes, product information, handling instructions, or internal identification. The bright white finish helps printed text and graphics stand out, while the pressure-sensitive adhesive backing allows fast peel-and-stick application to many common packaging and storage surfaces.
Supplied as a box of 100 sheets, these labels are a practical choice for offices, warehouses, ecommerce fulfilment, schools, and facilities teams that need consistent, easy-to-print labels without investing in specialist label printers. Use them with standard office printers (where suitable) to create tidy, repeatable labels that improve organisation, traceability, and presentation.

139 x 99.1mm No.4 White S/A Labels — Full Product Guide
Choosing the right sheet label is about more than just dimensions. Print performance, adhesive behaviour, and how the label will be used day-to-day all affect results. This guide explains how No.4 139 x 99.1mm white self-adhesive sheet labels typically fit into common workflows, what to consider before printing, and how to get the best finish when applying labels to packaging and storage items.
How It Works
Each sheet contains multiple pre-cut labels on a backing liner. You print your design or text onto the sheet using a compatible printer, then peel each label away from the liner and apply it to the target surface. The adhesive is pressure-sensitive, meaning it bonds when you press the label down firmly. For best results, apply to a clean, dry surface and smooth from the centre outward to reduce air bubbles and edge lift.
The 139 x 99.1mm label size is particularly useful when you need a larger print area—such as full address blocks, multiple barcodes, or combined shipping and internal tracking information—without resorting to oversized labels that waste space.
Materials and Construction
These are white self-adhesive sheet labels supplied in a boxed quantity of 100 sheets. The label face is designed to accept printed information clearly, while the backing liner supports smooth feeding and easy peeling. As with most sheet labels, performance can vary depending on printer type, toner/ink coverage, and the surface you apply the label to.
Tip: If you are printing heavy blocks of colour or large graphics, allow adequate drying/curing time (especially for inkjet printing) before stacking sheets or applying labels to avoid smudging.
Printer Compatibility and Print Quality
Sheet labels are commonly used with standard office printers. To achieve consistent results:
- Check printer settings: Select an appropriate media type (often “Labels” or “Heavyweight”) if available.
- Use the correct feed path: A straight-through or rear feed (where available) can reduce curling and improve alignment.
- Test print first: Print one sheet to confirm alignment, margins, and barcode readability before running a full batch.
- Avoid overloading trays: Feed smaller stacks to reduce the chance of multi-feeds or skew.
For barcodes and QR codes, ensure adequate contrast and quiet zones. A white label face helps maintain readability, but print settings and resolution still matter—especially for smaller codes.
Surface Compatibility
Self-adhesive labels generally adhere best to smooth, clean, dry surfaces. Typical compatible surfaces include:
- Cardboard cartons and paperboard packaging
- Plastic mailers and shrink wrap (depending on finish and additives)
- Glass and painted metal (clean and dry)
- Office storage items such as folders, archive boxes, and plastic totes
Challenging surfaces—such as dusty corrugated board, textured plastics, waxed coatings, or very cold/condensing items—can reduce adhesion. If your application involves extreme temperatures, moisture, or long-term outdoor exposure, consider testing first or selecting a specialist label/adhesive type designed for those conditions.
Health and Safety
Sheet labels are straightforward to use, but good handling practices help maintain quality and reduce waste:
- Store flat: Keep sheets flat in their box to prevent curling and feeding issues.
- Keep dry and clean: Moisture and dust can affect print quality and adhesion.
- Use clean hands: Oils and residue can reduce adhesion at the edges.
- Printer safety: Follow your printer manufacturer’s guidance for label media to avoid jams or adhesive transfer.
Ideal Applications and Use Cases
The No.4 139 x 99.1mm format is a strong all-rounder for organisations that need a larger label face without moving to dedicated thermal label rolls. Common scenarios include:
- Ecommerce fulfilment: Print address labels and internal pick/pack identifiers on the same label size for consistent workflows.
- Warehouse operations: Create bin labels, shelf labels, and carton identifiers that remain readable at a glance.
- Manufacturing and assembly: Apply work-in-progress labels, batch identifiers, or inspection notes to outer packaging.
- Office administration: Archive and filing labels where clarity and uniformity matter.
- Facilities management: Label equipment cases, storage cupboards, and consumable bins for faster replenishment.
Maintenance, Cleaning and Care
To keep labels performing well from print to application:
- Storage: Keep the box closed when not in use to protect from dust and humidity.
- Temperature: Store at normal room temperature where possible; avoid leaving sheets in hot vehicles or unheated warehouses for long periods.
- Handling: Avoid bending sheets; creases can cause misfeeds and misalignment.
- Application: Press firmly across the whole label, paying attention to corners and edges.
If labels are being applied to cartons in a fast-paced environment, consider standardising placement (same corner/face each time). This improves scanning consistency and reduces handling time.
Case Study (Example Workflow)
Scenario: A small fulfilment team ships mixed orders daily and needs a simple, scalable labelling process using existing office equipment.
- Step 1: Export orders from the shipping platform and format labels to the No.4 139 x 99.1mm layout.
- Step 2: Print a test sheet to confirm alignment and barcode readability.
- Step 3: Print batches of sheets, allowing time for ink/toner to set before stacking.
- Step 4: Apply labels to clean carton faces, smoothing from centre to edges.
- Result: Clear, consistent labels that improve carrier acceptance, reduce mis-reads, and present a professional appearance to customers.
This kind of workflow is especially useful when you want the flexibility of sheet printing (easy edits, mixed label content) without changing hardware.
