US Patent:

60337621, Mar 7, 2000

Filed:

May 8, 1998

Appl. No.:

9/074828

Inventors:

Thomas A. Decker - Convent Station NJ

Assignee:

Decker Tape Products, Co., Inc. - Fairfield NJ

International Classification:

B32B 900

US Classification:

428201

Abstract:

A self-wound, self-adhesive, resealable tamper-evident tape is provided. The tape is used to seal any container requiring a self-adhesive closure, such as bags or pouches, and provides clear visual evidence if the self-adhesive seal is peeled apart. The tape comprises a backing sheet, the upper surface of which is coated with a release layer, and the bottom surface with an adhesive. The release layer is relatively non-adherent to the adhesive so that the tape may be wound or rolled up without a separating liner. A non-visible patterned varnish layer is applied to the adhesive to create a hard surface onto which an colored ink layer is subsequently applied. The colored ink layer breaks or chips when the self-adhesive seal is peeled apart and retains this appearance if the tape is reapplied to seal the container, thereby providing visible evidence of tampering.
