Plastic or aluminium containers for sealing coffee powder in pure form

The most important formative characteristics of coffee capsules are the shape of the capsule, the thickness of the wall, and the thickness and location of the oxygen barrier layer. The single-sided profile of the flange area must also be measured together. Since the gap is 20 μm to 50 μm, the level of measurement inaccuracy required is in the middle range. The thickness and location of the oxygen barrier layer are directly related to the freshness preservation performance of coffee, so that industrial CT can be used to accurately analyze multilayer structures in a non-disruptive manner without single-sided damage.
