Self-adhesive labels 3l Biella 510021 — rectangle, permanent adhesive, transparent

3l Biella 510021 self-adhesive labels are transparent rectangular stickers with a permanent adhesive designed for durable labelling on documents, folders and packaging. The clear surface provides good contrast for both printing and handwriting while preserving the underlying content visibility. These labels are intended for use on smooth, clean surfaces and offer a discreet finish that keeps printed information legible without covering important text or graphics.

Advantages

Transparent rectangular format allows unobtrusive labelling while maintaining legibility of printed or handwritten text. Permanent adhesive ensures reliable bonding on a variety of smooth surfaces, reducing the risk of peeling. The label material is suitable for standard office printers and manual writing instruments, enabling flexible application methods. A consistent rectangular shape simplifies alignment and layout when labelling documents, folders and packaging.

Suitable for

• Labelling documents and folders in offices and archives
• Identification of packaged goods and envelopes
• Temporary overlays where underlying text or graphics must remain visible
• Manual handwriting or printing with inkjet/laser-compatible labels

Key specifications

• Shape: rectangular
• Adhesive type: permanent
• Finish: transparent/clear
• Surface compatibility: smooth surfaces such as paper, coated paper, plastic and glass

How to use

Ensure the application surface is clean, dry and free from dust or oils. Peel a label from the backing and position it carefully over the intended area; once applied, press from the center outward to promote full adhesion and remove air pockets. For printed labels, follow your printer manufacturer’s guidelines for label media settings and test a sample sheet before full runs. For handwriting, use pens or markers appropriate for non-porous surfaces to avoid smudging.

Usage recommendations

Store labels flat in a cool, dry place away from direct sunlight to maintain adhesive performance. Avoid applying to rough, dusty or textured surfaces where permanent adhesion may be compromised. For long-term archival labelling, test a small area to confirm compatibility with the document material and ink type.
