The product can be printed by all conventional roll label technologies including offset litho, UV letterpress and UV flexo.

Aggressive acrylic adhesive provides high bond and excellent destructibility on most substrates, including metals, powder coated surfaces, and plastics, including many low surface energy materials


Low shrinkage vinyl produces dimensionally stable labels without adhesive ooze or dirty edges

Application Ideas

Typical applications are for secure ‘closures’ in pharmacy, cosmetic, electronics and automatic spares.The product may additionally beused as a shrink label giving shrinkage in the machine direction after application to non-uniform surfaces when subjected to heat (-40% at 105 Deg. C). Other application areas may be in heat and sound insulation - where the relatively thick foamed layer will act as a non-conductive barrier, plus as a friction or anti-scratch label for table protection when applied to the base of trophies etc.

The above does not represent any guarantee or warranty and the Purchaser must independently determine the suitability of the products for the Purchaser's purposes.


Assume all surfaces are without contaminated – metals may be oily or dusty, plastic may be coated with mold release agents, dirt, etc. Any surface contaminant will adversely affect adhesion and the ability to destruct; therefore, contaminants must be removed prior to application by wiping with a solvent such as isopropyl alcohol.

Application temperature, pressure, and dwell time are all important variables to produce adequate adhesion and assure the label fractures when removal or tampering is attempted. For best results, the label should be applied when all materials are over 10°C. Higher initial bonds can be achieved through increased application pressure (firm hand or squeegee pressure should be sufficient). The bong will increase in time, depending on the substrate. Metals and high surface energy materials will develops bonds faster than low surface energy materials. For best results, wait 24 hours (at room temperature) before subjecting to harsh environments.


As with all pressure sensitive materials, this product should be tested thoroughly under end-use conditions to ensure it meets the requirements of the specific application.
