The properties of cigarette packaging materials are the key factors affecting the storage period in relation to the different storing environments. This article analyzes the testing demands of BOPP film (bi-axially oriented polypropylene film), and introduces the tests for several properties of BOPP film, including water vapor transmission rate , flavor protection, coefficient of friction, heat shrinkage and thickness, etc. Continue reading

New materials and new solutions are introduced and applied in the field of pharmaceutical packaging and medical apparatus, yet, the limitations of existing testers are becoming acute. Thus, how to eliminate deviations caused by changes of standards, materials and external forms, is greatly concerned by manufacturers and testing institutions. Based on the situation, Labthink has proposed a set of solutions, which can not only extend the instrument applications, but also have advantages in testing range, purchasing costs, instrument maintenance, operation safety, structural optimization and extended applications, etc. Continue reading
