This aluminum tape cuts in straight lines. We developed it to fasten ventilation ducts, insulation, and other materials.


  • This product uses a special synthetic rubber adhesive. This gives it highly stable adhesive strength at low temperatures.
  • It uses Caralyan Y (special PE film), making it easy to tear cleanly by hand.
  • It has no peel sheet, reducing the amount of industrial waste.
  • It can be affixed in layers, giving it superb functionality when used in half-overlapping layers.
  • It uses an environmentally friendly non-solvent rubber hot-melt adhesive.
  • We offer both glossy and non-glossy (matte) types. Choose the one that suits your needs.
  • This product does not intentionally use toxic substances designated by the EU’s RoHS Directive.
