Muindasitiri yekurongedza, iyo substrate yekatoni inoreva rudzi rwezvinhu izvo katoni yauri kuisa chisimbiso inogadzirwa kubva.Rudzi rwakajairika rwe substrate corrugated fiberboard.

Pressure-sensitive tepi inoratidzwa nekushandiswa kwekupukuta-pasi simba kutyaira inonamira mumafiber eiyo substrate yakasarudzwa, uye misiyano yekunamira yekugadzira inogona kukanganisa kuti inonamatira sei kune akasiyana substrates.
