tein-based membranes. 5. Conclusions
Bio-polymer based coating on paper packaging materials are very important systems for the future improvement of food packaging. They have potential en- vironmental advantages over conventional petroleum-based paper coatings. A literature survey indicates that bio-based polymers have a great potential for re- placing hydrocarbon-produced synthetic polymers as a sustainable solution for paper coating applications. Not only can biopolymer paper coating provide bio- degradability and renewability, but numerous methods for increasing the func- tioning of coated paper surfaces have been proposed. An appropriate mix of chosen ingredients (bio-derived polymer and fillers) and surface structure, ac- cording to the review, has the ability to offer an entirely impenetrable bio-based paper coating. From the presented review, appropriate bio-based polymers like starch, polylactic acid, itaconic acid, lignin, soybean protein and cellulose, pro- vide a fully protective bio-based paper coating. Finally, the difficulties associated with most biopolymers, such as hydrophilic- ity, crystallization behavior, brittleness, or melt instabilities, prevent their full industrial exploitation. This study cites investigations in which it was observed that mixing with other biopolymers, compatibilizers, and plasticizers might as- sist in alleviating this bottleneck. But extensively research will be needed in the paper packaging industry towards insubstantial materials for reduction of raw material use, conveying costs, minimizing the amount of waste and improve- ment in the performance properties of paper coatings. Interest in sustainable materials combined with improvement in performance properties of paper coating will continue to growth.
