Shrink Tack Label (STL)
The Future of Efficient, Secure Pharmaceutical Labeling.
IL Group’s Shrink Tack Label (STL) technology offers an innovative approach to pharmaceutical and hazardous drug packaging—combining labeling and sealing into a single, compact process. STL is a heat-shrinkable label with pressure-sensitive adhesive, delivering both containment and clarity with minimal heat exposure.
Ideal for applications requiring high containment, tamper-evidence, and compact labeling operations, STL simplifies and strengthens your packaging line.
What Makes STL Different?
Unlike traditional shrink sleeves or standard pressure-sensitive labels, STL brings together the best of both technologies:
Heat-Shrinkable Tack Label
A uniaxially extended film with pressure-sensitive adhesive on the back, shrinks securely with low heat exposure.
Label + Seal in One Machine
Simplify your operation. STL allows for labeling and sealing in a single machine, reducing footprint and streamlining production.
Enhanced Containment & Protection
Provides shatter control and high containment for hazardous or high-risk pharmaceuticals.
Precise and Adaptable
Depending on your usage, labels are available in multiple material types and colors.
