Mactac Launches New Tamper-Evident Labelstock

Mactac® has launched a new, innovative tamper-evident labelstock designed to increase brand protection against product tampering, warranty fraud and asset theft.

A non-PVC, destructible labelstock, the tamper-evident product, LTCNVP50, has a unique balance of high tensile strength with low internal strength making it easy to convert on press, but extremely difficult to peel off or remove once applied. Upon attempted removal, the material fractures easily, causing irreversible damage and preventing subsequent re-application.

“Created with brand and product protection in mind, this labelstock is one-of-a-kind,” said Kim Hensley, marketing manager, Mactac Performance Adhesives. “Its design is unique in that it has 50 percent higher tensile strength than conventional destructible vinyl, yet low internal strength once applied to the surface, producing a fragile facestock that is still easy to convert. It also offers consistent printability and is proven to run faster than other destructible products on the market today.”

LTCNVP50 consists of:

  • A 2.0-mil white matte non-vinyl film facestock that has been top-coated for excellent flexographic and thermal transfer printing.
  • A high-performance permanent acrylic adhesive with aggressive initial tack that offers very good adhesion to high and low energy surfaces, as well as temperature and humidity resistance.
  • A 45# blue glassine liner excellent for die cutting and stripping.

It is designed for use in industrial and electronic packaging device identification, warranty and asset protection and automotive VIN labels and security seals. Highly versatile, it can be used for a variety of applications, such as asset labels, product warranty labels and pharmaceutical box seal labels.

“Product tampering and theft are ongoing issues for brand owners in numerous industries making it highly important to incorporate product labeling as part of brand defense systems,” adds Hensley.

LTCNVP50 fully meets RoHS10 compliance of restricted materials.

It was originally developed by Mactac’s parent company, LINTEC Corporation, which provides a wide range of pressure-sensitive papers and films to produce labels and seals for a variety of applications, such as food labeling, consumer electronics and automotive identification.
