Crêpe paper is thin, textured, and often colorful decorative paper used inpaper craft. It is created by adhering wettissue paper to the cylinder of aYankee dryer and then scraping it off with a blade once dry.[1] This process creates gathers in the paper, giving it a crinkly texture like that ofcrêpe. This creasing process is called creping or crêping.
Paper that is creped is produced on apaper machine that has a single large steam-heated drying cylinder (yankee) fitted with a hot-air hood. The raw material ispaper pulp. TheYankee cylinder is sprayed withadhesives to make the paper stick. Crêping is done by the Yankee'sdoctor blade that scrapes the dry paper off the cylinder surface. The crinkle (crêping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
Crêpe paper and tissue are among the lightest papers and are normally below35 g/m2.
The crêpe ratio reflects how much the paper has shortened during crêping. The figure is normally between 10 – 30%. Crêping is used to adjust the paper's stretch and thickness, both of which have a marked effect on softness and absorbency.
Crêping can also be applied to specialty papers, such as microcrêping insack paper.
