Plastic-free, oil- and water-resistant paper for food packing
Source abstract
Abstract
Abstract Traditional food packaging coated paper is not environmentally friendly, and there have been many studies on oil- and water-resistant paper for food packaging. However, preparing oil- and water-resistant paper that is plastic-free, fluorine-free, and environmentally friendly is still a significant challenge. In this study, oil- and water-resistant paper for food packaging are prepared by layer-by-layer assembly and mixing coating methods. The layer-by-layer assembly coated paper exhibits excellent water resistance (Cobb 60 value of 20.5 g/m2, water contact angle value of 132°). The mixed coated paper not only has good water resistance (Cobb 60 value of 27.1 g/m2, water contact angle value of 131°), but also has excellent oil resistance (kit rating value of 8/12). The oil-resistant and waterproof mechanism of the coated paper is confirmed through scanning electron microscopy. In addition, the mechanical performance and coating adhesion of the mixed coated paper are the best, with an increase in the tensile index of 73.1 %. This study provides a feasible strategy for preparing biodegradable, plastic-free, and fluorine-free food packaging oil- and water-resistant paper, which is beneficial for reducing plastic pollution.
