GBD-L2 falling dart impact tester is suitable for testing materials such as plastic film or sheet and steel plate coating with a thickness of less than 1mm. Under a given height of free falling dart impact, it can measure the energy (in Quality to express results) of plastic films,thin section specimens and other materials. Through the impact resistance test, it can prevent the packaging surface from being damaged when the packaging material is impacted or dropped due to insufficient toughness of the packaging material, and effectively avoid the product from being damaged due to impact or falling in the circulation link. It can be used in scientific research, teaching, industrial and mining enterprises, laboratories, research institutes and quality supervision departments.

Paper Air Permeability Tester tests the air permeability, air permeability resistance of paper and cardboard. It adopts the testing principle of differential pressure method and combines Gurley method, Schauer method and Bengtsen method.

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.
