In addition to producing its own barrier-coated bottles in-house, Martens also sells newly made PET bottles to other interested breweries. The recyclable PET bottles receive a wafer-thin glass coating during the Plasmax process. This coating prevents oxygen from penetrating the bottles and carbon dioxide from escaping. The coating ensures extended beer shelf life and preserves product flavor quality. After the bottles are produced, they are temporarily stored before filling. One of the largest brewers in Belgium, Martens packages its own in-house brands, as well as international private labels under filling contracts. The brewer uses fillers manufactured by several companies, including a computer-controlled, Innofill DVP pneumatic pressure, volumetric filling system from KHS.
