The present invention discloses a method for dispersing and exfoliating fillers in a thermoplastic polymer by sonicating a mixture of the thermoplastic polymer and the filler. The adhesive coating method moves a coating unit at a first speed for forming a plurality of adhesive dots, which are separated from each other by a first distance in a straight section, and the coating unit coats an adhesive for forming the adhesive dots on the first substrate. The mechanically weakened regions of the web enhance the dispersibility of the product. These labels can be bonded to substrates of glass, plastic, or metal using a water based adhesive which is in contact with the nano-porous layer.
