Self-adhesive lidding film for packaging electronic components, whose adhesive layer is covered with a non-adhesive covering in the center, wherein the adhesive layer comprises a mixture of two acrylate adhesive compositions of different polarity, the first, highly polar component containing from 1 to 20%, in particular from 6 to 10%, especially about 8%, of acrylic acid in the monomer composition, and the other, nonpolar component containing from 5 to 50%, in particular from 10 to 30%, especially about 20%, of stearyl acrylate in the monomer composition, and where an adhesion promoter or primer is present between the adhesive layer and the film support of the lidding film.

Self-adhesive lidding film for packaging electronic components

An adhesive tape is disclosed which is useful for binding electrical conductors. The tape is liquid-permeable so that the conductors can be impregnated with liquids such as varnishes and resins. It comprises a liquid-permeable support material, one side of which is coated with an adhesive. The adhesive covers less than 50% of the coated side.
