VOID sticker material is a kind of revealing sticker anti-counterfeiting material with plastic film as the base material, also known as anti-counterfeiting character mold. Its feature is that when the label is lifted, the pre-set text or patterns, such as "VOID", "unsealed", "opened", etc., will separate from the surface material and remain on the object to be affixed, thereby achieving the purposes of anti-counterfeiting and anti-tampering
