Its quality directly affects cosmetics safety during distribution. The testing items include: tensile strength & elongation rate, peeling strength of laminated films, heat seal strength, sealing and leakage, impact resistance and surface smoothness, etc.

  • Tensile strength is the maximum force before material breakage so as to resolve the problem of inferior mechanical strength and the corresponding package breakage under external forces. Peeling strength is also called composite strength or compound strength; it is the testing of the bond strength between the layers of the laminated film. If the bond strength is too low, separation of layers and leakage are easily to appear during application. Heat seal strength is the testing of the enclosure strength. During product storage and transportation, the heat seal place would break and the content would leak if the heal seal strength is too low.
  • In order to test the above-mentioned indexes, tensile tester is a necessity. Take Labthink XLW (PC) Auto Tensile Tester as an example. Prepare specimens according to different standards, clamp the specimen in between the clamps of the tensile tester and set the testing speed at 300mm/min (for tensile testing, 500mm/min is also available). Start the tester and the testing results would be calculated. XLW (PC) Auto Tensile Tester is equipped with function menu, through which, standard testing can be accomplished by choosing different testing items. Besides, for heat seal strength testing, Heat Seal Tester is needed for the specimen preparation. This instrument is a routine instrument in cosmetic packaging labs.

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.

Commonly, 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.
