Abstract
Environmental evaluation of two different oxygen high barrier films were performed using life cycle assessment. One of the films (traditional film) was composed of aluminum oxide coated PET film, ink, LDPE and LLDPE. Another film (new film) was consists of PET, ink, protein based coating material, LDPE, LLDPE. Main layer to achieve the high oxygen barrier for traditional film was aluminum oxide coated PET film, whereas the protein based coating material act as oxygen barrier layer for new film. Functional unit of this study was 1000 pouches made of traditional and new film. System boundary was factory to gate. The results of this study revealed that the new film shows better environmental performance for most of impact indicator than traditional film, except marine eutrophication and fine particulate matter formation due to extra coating process in new film system.
