On June 18, 2022, Müller AG Verpackungen in Münchenstein opened its doors to customers, business partners, family members and the general public. Around 3,000 visitors found their way to Tramstrasse - despite extraordinary heat that reached a blistering 36 degrees. The mood was exuberant. The guests were satisfied, also because of the catering of Eiche Metzgerei, Basel, which left nothing to be desired.
