Abstract:
1) An HMPSA composition comprising:
from 20% to 50% by weight of a composition of styrene block copolymers;
from 35% to 65% by weight of one or more tackifying resins; and
from 7% to 25% by weight of a plasticizer consisting of a composition comprising a stand oil of a vegetable oil.
2) A multilayer system comprising:
an adhesive layer (A) consisting of said HMPSA composition;
a printable support layer (B) adjacent to the adhesive layer (A); and
a nonstick protective layer (C), adjacent to the adhesive layer (A).
3) The use of said multilayer system for the manufacture of self-adhesive articles.
