Plasters medical fixing (adhesive tape) is used for fixation of compresses, tampons, bulk 
and tight post-operative dressings and coatings. When creating adhesives for medical 
purposes originate from the fact that they should be non-toxic, have optimum adhesion to

the human skin and also sufficient adhesion to the substrate, so that the tape can be removed 
from the skin without damaging the integrity of the adhesive layer.

that is sensitive to pressure. As a base can be applied include various fibrous materials
