The most important functions of the packaging are protection of the contents, storage as well as transportation. Therefore, lightproof surface, ergonomic shape and robust design are required.
Leakages are regarded as a critical defect. Leaky packaging can cause damages that adversely affect the quality and appearance of the product. For that reason, the conducting of leak tests is so important for us.
In the run-up to the leak test a conformity check of the bottle and the corresponding closure is conducted. This procedure ensures that the closure or trigger sprayer can be tightly screwed on the bottle and sits properly. The thread must also fit.
In case the conformity check is successful, a leak test is be conducted via a vacuum inspection according to the DIN 14401.
