PRESSURE SENSITIVE
A term commonly used to designate a distinct category of adhesive tapes, adhesive
labels and adhesives which in dry (solvent free) form are aggressively and
permanently tacky at room temperature, and firmly adhere to a variety of dissimilar
surfaces upon mere contact without the need of more than finger or hand pressure.
They require no activation by water, solvent or heat in order to exert a strong
adhesive holding force toward such materials as paper, plastic, glass, wood,
cement and metals.
Pressure sensitives have a sufficiently cohesive holding and elastic nature
so that, despite their aggressive tackiness, they can be handled with the
fingers and removed from smooth surfaces without leaving a residue. General
trade usage by leading tape manufacturers does not sanction extension of the
term "pressure sensitive" to embrace tapes and adhesives merely
because they are sticky, eg. fly paper, or merely because they adhere or cohere
to a particular type of surface, eg. self-sealing envelopes: and terms other
than "pressure sensitive" should be used in such cases to avoid
confusion.
PRESSURE SENSITIVE LABEL
Misused terminology - Self Adhesive Label. Labels are not self adhering, and
require pressure to help the adhesive ‘grab’ the surface to which
they are applied to; therefore Pressure Sensitive is the correct term.
A pressure sensitive label product is the die cut part that has been converted
through flat sheet or roll fed production equipment utilising the type of
pressure sensitive labelstock which has a protective liner. The end product
is produced in the form of either rolls, sheets, fanfolds or singles, or by

converted labelstock rolls.
