REPOSITIONABLE PRESSURE-SENSITIVE ADHESIVE TAPE AND METHOD OF MAKING |
摘要 |
<p>A pressure-sensitive adhesive tape or sheet is reliably repositionable by having a plurality of spaced clumps of particles uniformly distributed over at least one surface of the pressure-sensitive adhesive layer with the tips of the clumps of particles being substantially free from adhesive, which particles are smaller than the thickness of the pressure-sensitive adhesive layer. Preferred particles are glass beads which may be from 5 to 15 mu m in diameter when the thickness of the pressure-sensitive adhesive layer is about 25 mu m. Each clump preferably contains from 5 to about 100 particles. The pressure-sensitive adhesive layer can be covered with a carrier web which has a low adhesion surface that is formed with depressions that protect the clumps of particles.</p> |
