BOPP cigarette film tensile strength, elongation and elastic modulus are important to BOPP film.Cigarette package requires high tensile strength of BOPP films, which can greatly reduce the breakage during packaging process. Generally, 140N/mm2 vertically and 200N/mm2 crosswise are required. Elongation rate is for analysis of incision easiness of films. Cigarette packaging industry is different from other industries. Higher elongation rate is not better. Max. limitations of 200% vertically and 80% crosswise can guarantee easy incision and assembling smoothness. Other industries require those two indexes. But cigarette package requires more detailed requirements on incision easiness during high speed production. Therefore, Elastic Modulus testing is also put forward. Labthink PARAM XLW(PC) Auto Tensile Tester is the professional tester for film and its tensile strength with Elastic Modulus testing. Low Elastic Modulus would lead to worse stiffness, unsuccessful production procedure and inferior incision easiness as well as package breakage and film obstruction. Usually, Elastic Modulus is required to be above 2000N/mm2 for cigarette film. However, when testing Elastic Modulus, testing conditions and temperature must be emphasized. Otherwise, the results will fluctuate greatly. Therefore, testing condition must be stated.
