Ever looked at the back of your TV, under your router or at your boiler? You'll see the same thing: grey, metallic-looking technical labels with "Serial No", "220V", "Warning" and so on.
In electronics and appliances, these labels are the device's ID card. If they fall off or fade, warranty tracking fails, service technicians can't help, and safety information is lost.
Here's why manufacturers insist on metallized (silver matte) roll labels, and how they survive the device's whole life.
1. The Label That Doesn't Fall Off Warm Devices
Electronics warm up in use. TV panels, routers and fridge compressors give off constant heat. A standard paper label's adhesive dries out and the label soon drops off.
Metallized (silver matte) labels use heat resistant acrylic adhesive. As the device warms, the adhesive grips even tighter. However long the device runs, the label stays put.
2. Serial Numbers and Warranty Tracking
When a product comes in for repair, the technician looks first at the serial number label. If the barcode has worn off, warranty status can't be confirmed.
Printed with durable resin-based print, these labels:
- keep barcodes readable for years,
- don't lose text when the customer cleans the device with household cleaners,
- resist friction.
3. Electrical Safety and Warnings
Voltage ratings (220V/110V), earth symbols and "Do not open" warnings are vital and must stay legible.
Although metallized labels look metallic, they're actually plastic film, so they don't conduct electricity. That makes them well suited to rating plates and safety labels; always check the requirements of the standards that apply to your product.
Uses by Sector
| Device group | Purpose |
|---|---|
| Large appliances | Model number, energy class, motor power. |
| Small appliances | Technical data and warranty labels on the base. |
| Computers & IT | Asset barcodes on cases, license key labels. |
| Lighting | Lumen and wattage data inside fixtures (exposed to heat). |
Conclusion: Protect Your Brand's Reliability
When customers see a device with a peeling label and faded text, they question the brand. Complete your product's quality with a label that's just as durable.
