Global Engineering Corporation supplies Paper Curl Tester. Global Engineering Corporation offers wide range of quality testing equipments used in various industries. The Paper Curl Tester is used to measure the degree of curl when the paper sample exposed to water. Paper curl can be defined as a systematic deviation of a sheet from a flat form. It results from the release of stresses that are introduced in to the sheet during manufacture and subsequent use.
Paper curl system has been a persistent quality issue and is increasingly important for paper grades being subjected to high-speed printing, xerography and high precision converting processes.
There are three basic types of curl; they are mechanical curl, structural curl and moisture curl.
