Definition statement

This subclass covers:

Adhesive tapes, films or sheets characterised by having an outer adhesive layer to be applied to a substrate. Said outer adhesive layer might be covered by a release liner or a release sheet (Fig.1).

Adhesives in the form of films or foils without carriers.

Adhesives in the form of films or foils on carriers, e.g. plastics, paper, textile fabrics or laminated material.

Carriers with adhesive in the form of films or foils.

Release liners of adhesives in the form of films or foils.

Release coatings on the carrier.

Primer between the carrier and the adhesive

The figure shows a carrier mounted adhesive film with a barrier layer, a primer coating, a release coating on the carrier layer and a release liner.

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

Pressure-sensitive adhesive Pressure-sensitive adhesive (PSA, self-adhesive, self-stick adhesive) is adhesive which forms a bond when pressure is applied to adhere the adhesive with the adherend. No solvent, water, or heat is needed to activate the adhesive.
Metallised plastic Metallised plastics are plastics coated with a thin layer of metal, usually aluminium. Metallisation is generally performed using physical vapour deposition, plating or thermal/cold spraying processes. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres.
Heat-activated adhesives Heat-activated adhesives are designed to bond parts or components through the use of heat (over 50 ℃).
