The adhesive adhesive coating is applied to both sides of the tape, and the antiadhesive coating composition is applied on both sides. on both sides of the base paper, then Both materials are duplicated. It is preferable to use a double-sided adhesive tape for folding into the printing web in web-fed printing machines. The test is subjected to two-sided and the heat resistance is determined based on the shear strength of the K.ie compound 1 and the paper-for. three samples and 20x20 m of tasmero, CHIS and a1; tiadhesion of paper% and on both sides of the sample impose podoski of writing b-magic size.

Three specimens with a size of 20x20 im are cut out of the selected section of sticky tape over an iab.chon. they remove anti-adhesive paper and on both sides of the sample they apply pouches of writing paper measuring 20x100 mm. Rolled over the bonding area by roller and after 5 min, the strength of adhesive bond 6y iai4f is determined by shearing on the dynamometer at a moving speed: Kenya clamp 100 mm / min; adhesion of the kdeic coating to the anti-adhesive resistance to peeling them from each other. Samples with a size of 15x150 mm are cut out of adhesive tape and the peeling strength of the adhesive coating from the adhesive tape on a tensile machine with a spinless force meter with a movement speed of 1-1 clamp 100 and a peel angle of 180 is determined.
