Packmatic’s APET-PEfilm also impressed technically. During qualification, the films were tested onstandard GEA, Multivac, and Ulma machines. In addition, Berger’s in-house laboratory conducted durability tests, measured gas levels, and assessed the residual oxygen and discoloration of the product. “The material has to work flawlessly - otherwise we can't list the item at all,” emphasizes Berger. The films performed perfectly in the first test run - they were machine-compatible from the start, visually and haptically identical to the previous ones, and met all quality requirements.

Berger now also draws on Packmatic's expertise for development projects related to recyclable mono-material solutions. What makes the partnership with Packmatic special for Berger is not only the in-depth packaging knowledge and large supplier network, but also the human touch. Claudia Berger appreciates the short communication channels and the dedicated contact persons – "You can tell that someone really cares. It's straightforward, pleasant, and solution-oriented." The strength of the collaboration was particularly evident in challenging times, such as during COVID pandemic or in relation to the necessary changes for the upcoming PPWR. For Berger, it was a strategically important step to broaden its supplier base and choose partners who are not only technically and financially suitable, but also a personal fit.
