Enhance security with void protection

Ensure product integrity with high-security void labels | UPM Raflatac

Void films provide tamper-evidence and product authentication, protecting consumers and supporting their loyalty and trust in brands. They leave a text, pattern, or logo on packages and casings when the label is partially or fully removed, and they cannot be smoothed back down or repositioned undetected.

Our standard voids leave a sticky residue on the labeled substrate. When packages need to remain attractive and are part of a product’s value, No Tack voids leave a smooth and silky message that doesn’t attract dust or dirt. If the substrate should be kept intact and completely free of adhesive, our No Residue voids are the ideal choice. Our range includes films that fluoresce in a different color on the top and reverse under UV light, and materials that reveal void patterns in a different color to the exterior label.

Customized voids designed according to need

For special requirements we can create customized void solutions with texts, patterns, logos, and colors according to specifications from label end-users and brand owners. They are typically polyester (PET), but we also offer other filmic materials. These are designed for applications with highly demanding tamper-evident requirements, including pharma, automotive, and consumer electronics applications.

A range of features and finishes for void protection

Whatever your application, we have a void material that will enhance your brand while giving you the security you need.

  • Void Text Tinted TC 36 offers a unique darkish, semi-silvery, metallized transparent look.
  • Void Text 2Colour TC 50 has a green exterior, while the hidden text is revealed in blue.
  • Void Fluor Red/Blue TC 50 has a semi-covert security feature: when exposed to UV light, the top surface reflects in fluorescent blue (also supporting label detection), while the reverse reflects in fluorescent red.
  • Void Text Blue TC 36 and Void Text Red TC 36 are available in a range of colors and thicknesses.
  • Microvoid Blue PP TC 50 is a flexible material for labeling tightly contoured and small-diameter surfaces. The reduced void text size is ideal for smaller label sizes.
  • Void Clear TC 50 is a high-gloss, high-transparency polyester film with a checkerboard pattern.
  • Void Silver TC 50 is a metallized polyester film with a checkerboard pattern.
  • Void Text White TC 50 is a white polyester film with a ‘void’ text pattern.

Our text void solutions come in white, silver gloss, silver matt, red, and blue. Our No Tack voids are available in silver, while our checkerboard voids can be clear or silver.

Strong adhesives for void labels

RP37S is designed for use with film face materials, providing good initial tack and long-term adhesion on polar and non-polar surfaces. It performs well in a broad range of applications with good resistance to water, chemicals, oils, and UV light, as well as offering excellent UV stability once labeled.

RP77 is a general purpose high-tack adhesive for white films in combination with paper liners. This softer adhesive is typically used in the labelling of uneven PE and PP surfaces, providing immediate repositionability and then strong final adhesion.

RC18 is designed for films in combination with paper and filmic liners. Ideal for end uses requiring very good adhesion on polar and non-polar surfaces, it offers good temperature and chemical resistance.
