Etiqueta de impresora autoadhesiva HERMA Etiquetas de seguridad A4 Ø 40 mm redondas blancas

Self-adhesive printer label HERMA Security labels A4 Ø 40 mm round white are high-quality security labels on A4 sheets, designed for laser printers and copiers. Each pack contains 600 round labels (Ø 40 mm) across 25 A4 sheets with 24 labels per sheet. The labels are made from a special white film with safety adhesive that shows visible residue if removed, preventing unnoticed tampering. They feature strong adhesion, good flatness and an all-round protective edge to ensure trouble-free processing.

Advantages

These security labels resist tearing, repel oil and dirt, and tolerate a range of temperatures, while leaving an obvious residue when removed so the seal cannot be transferred to another object. They are optimized for reliable feeding and printing in laser printers and copiers and offer consistent matte finish and adhesion. The product is made in Germany and supplied in a format suitable for mass labelling tasks.

How to use

Load the A4 sheets into a compatible laser printer or copier according to the device instructions and print your labels using the template that matches 24 labels per sheet. After printing, apply a label to a clean, dry surface and press firmly to ensure full contact. Allow at least 30 minutes for the adhesive to reach minimum adhesion. Avoid applying to very fragile materials that split easily (for example untreated paper or thin cardboard) and to plastics containing plasticizers without prior testing.

Recommendations

Test adhesion on unfamiliar or low-surface-energy substrates (for example polypropylene or plasticized materials) before full application. Do not use outdoors. For colour printing needs, choose labels compatible with colour laser systems—these labels are suitable only for monochrome laser printers and copiers.
