PermaTrack Tamper-Evident Asset Tag Labels make it easy to create your own asset tags, bar-code labels, equipment tags, property tags and nameplates on demand, right from your laser printer. Allow 24 hours for the labels to set, and once lifted, these labels leave behind a checkered-pattern layer and cannot be reapplied, discouraging theft, tampering or warranty fraud. Chemical-resistant, tear-resistant and waterproof, these asset tags print smoothly without skewing or jamming. Use the free, online, Avery Design & Print software with bar-code generator to add text, graphics, serialized numbers or bar codes in just a few steps. Then print as many asset tags as you need when you need them, avoiding high minimum order quantities and long lead times from custom printing services. Tamper-Evident Asset Tags feature a strong adhesive to enable reliable identification and tracking for the life span of your asset. Each letter-size sheet includes 40 labels (3/4" x 1-1/2").
