We slit in rolls or die-cut to your exact specifications.


  • This tape has a moisture resistant polycoated kraft liner which can withstand high humidity conditions with minimal cockling or wrinkling.
  • This tape has a film carrier which can add dimensional stability to foams and other substrates and also make it easier to handle the tape during slitting and die-cutting.
  • The bond strength of 3M™ Laminating Adhesive 300LSE increases as a function of time and temperature, and has very high initial adhesion.

Typical Applications: 

  • Foam attachment for electronic assemblies.
  • Low surface energy substrates.
  • Graphic attachment of high surface energy and low surface energy.
