Sigmaguard

Small white box with white metal and white label on the tab

Sigmaguard™ is a cellulose acetate modified to allow the tear strength to be varied to meet the customer’s exact needs. When used as a label, seal, or over-laminate, attached by an adhesive, the film is almost impossible to remove without easily noticeable damage to the film itself or the surface to which it is attached.

Features

  • Highly frangible/destructible
  • Offers good printability
  • Highly transparent
  • Made from sustainable wood pulp

Benefits

  • Security – Provides visual evidence of tampering to retail staff and consumers
  • Deterrent – Can be clearly marked as a tamper-proof seal/laminate to deter the tamper and increase the consumer’s confidence

Typical Applications

  • Carton Closures– pharmaceuticals, foodstuffs
  • Over-Lamination– security passes, identity cards, passports
  • Indoor Anti-Vandal Signs– warning, information, and direction signs

4 Mil Polyart TE®

Polyart® is a polyethylene film, destructible by delamination for tamper-evident labels.
