Latest Patents

Stefan Büttner holds a patent for a recyclable polyethylene film, which consists of at least 80% polyethylene material and a maximum of 20% compatible polyolefin material. This film is designed to be less than 40 µm thick and features a central layer made of linear low-density polyethylene (LLDPE) and/or metallocene linear low-density polyethylene (mLLDPE). The film is structured with two outer layers made of high-density polyethylene (HDPE) that bond to the central layer. The HDPE content constitutes at least 60 vol%, with preferences for 70 vol% and even 80 vol%. Notably, the outer layers are at least three times thicker than the central layer, enhancing the film's durability. The polyethylene film is also stretched in at least one direction, improving its performance.
