Interlayer support, useful to deposit a self-adhesive material with a layer of self-adhesive, comprises a laminar substrate, an applied interface and a relief structure with raised webs

摘要

Interlayer support (A) comprises a laminar substrate (10), an applied interface (14) (on which a self adhesive material with a channels suitable to deposit in the pressure-sensitive adhesive layer (20)) and a relief structure (22) with raised webs, which forms substantially complementary channels in the self-adhesive layer, in which the air trapped during adhesion can escape in the pressure-sensitive adhesive layer. Interlayer support (A) comprises a laminar substrate (10), an applied interface (14) (on which a self adhesive material with a channels suitable to deposit in the pressure-sensitive adhesive layer (20)) and a relief structure (22) with raised webs, which forms substantially complementary channels in the self-adhesive layer, in which the air trapped during adhesion can escape in the pressure-sensitive adhesive layer (where the relief structure is an irregular polygon structure with stochastically formed and distributed polygons having 4-7 angles and connected by their angles). An independent claim is also included for self pressure-sensitive adhesive material with (A).
