Labels with protective function for the documentation of the initial opening or manipulation
These safety labels document the opening of parts or products and leave traces at the attempt to detach or to transfer the label. They tear or fragment at the predetermined breaking points in the material or leave residues, e.g. due to a multilayer material composition, whereby the inscription “void” remains on the substrate. Openly visible and also hidden safety features are possible, which will be only recognized during the manipulation attempt. Often several safety features will be combined.
The labels will be adjusted to the customer-specific requirements and applications and serve the product protection in the first place. Additionally, they can also carry further information like codes or producer information.
The main features of labels for the proof of initial opening or manipulation
- Produced of manipulation-proof and self-adhesive document foil
- Void-labels leave a checker pattern or inscriptions on the substrate and thus are no longer completely transferable
- Applied as a guarantee- and safety seal for the protection against unauthorized access
- High resistance for outdoor applications and in the area of chemicals and solvents
- Resistant to UV light and against aging
- Customer-specific hologram void-foils are possible
- High abrasion resistance with suitable thermal transfer ribbons for the thermal transfer printing
- Very high adhesive power also to difficult substrates
- Optimization of the processes by automation of material- and product flow
- Additional safety features like e.g. security cutouts are possible
- Numerous special materials by Avery, 3M, Flexcon, and Tesa available from stock
- Plain labels in individual formats and special forms
Functions and advantages– precisely tailored to your requirements for the labeling
An open packaging, an unauthorized access to electronic parts or limited products will be excluded by these safety solutions.
The labels with the protective function offer the best possible flexibility and will be adjusted individually to the customer’s requirements. This happens by using suitable special materials of leading manufacturers, individual die‑cutting forms and premium adhesives.
The labels can be inscribed directly as required in variable amounts with current data at the site, by that the storage and the management of numerous labels may be dropped.
Our upscale and accurate processing with most modern die-cutting technologies guarantees the highest precision and reliability for the application of labels. Thus even plain labels with adhesives which are difficult to process can be processed mechanically very well, which increases the user efficiency in the long term.
Frequently Asked Questions
Industrial applications of labels with protective function
The typical labeling products in the area of these labels are serialized labels, seal labels, void labels, decorative labels, and type labels. These labels can be applied for example in the following branches and areas:
- Certification/inspection (inspection plates, test seals)
- Electronics industry (the evidence of the opening of parts)
- Mechanical engineering (engines, machines, and machine tools)
- Electric tools engineering (tools, home appliances, office machines etc.)
- Car manufacturing (OEMs, supplier)
- Vehicle construction (public transport, freight transport, ships and train construction)
- Medical products (active, non-active and products with measuring function)
- Chemical industry
Individual features of seal-labels and void-labels
Very flexible materials for adhesion around corners and edges so that the labels can also serve as the closure of a packaging. Also material compositions and partially preprinted logotypes are possible.
Technical key data of our protective labels
- Temperature resistance from +150° C (302° F) C to -40° C (-40° F), with safety effect up to +80° C (176° F)
- Very thin (minimum 6µ) and very thick (175µ) combinations of foils possible
- High-performance materials made of polypropylene (PP), polyethylene (PE), polyvinylchloride (PVC)
- Permanent adhesives with a very good adhesive power for high- and low-energy substrates
- Customized effects like e.g. company logotypes in holograms possible
- Diverse carrier materials like compressed kraft paper in different thicknesses, transparent plastic liner, kraft paper siliconized on both sides, and environmentally stable kraft paper available
- Subsequently inscribable with thermal transfer printing method
