Product Detail

Tamper-resistant security envelopes are the best solution for moving classified materials and valuable items. Any attempt to open the security tape will cause the word "VOID" to appear. Any attempt to dissolve the glue will cause a partial disappearance of the color. Any attempt to separate the edges will make it impossible to restore them. Other features include padded construction, bar code, numerator and a unique logo on the glue strip that is undetectable to the bare eye and impossible to copy.
