MSI produces 2 types of Tamper-Evident labels.
"Void" Polyester: The adhesive has been die cut to expose the word "Void" upon removal. This makes it impossible for someone to re-use the labels on another product.
Destructible Vinyl: This is a .002 Vinyl manufactured to be very brittle. Upon removal the label will break into tiny pieces making clean removal impossible.
