Outline
Traditional petroleum-based plastic wrap is difficult to degrade and causes serious pollution.Meanwhile, the post-harvest loss rate of fruits and vegetables is high, so there is a need to develop green and efficient alternative packaging materials. Polylactic acid biodegradable cling film is an environmentally friendly packaging material made from plant-based sources like corn starch, which can decompose naturally. Due to the good processability, mechanical strength and biodegradability, polylactic acid is highly competitive in the field of fruits and vegetables preservation packaging. This paper reviewed the preparation methods and properties of polylactic acid biodegradable cling films for fruits and vegetables, as well as the practical applications in fruit and vegetable preservation, and explored potential future developments. Future research should focus on multifunctional synergy, intelligent responsiveness, and low-cost, large-scale preparation to accelerate the practical application and promotion of polylactic acid biodegradable cling films. This study aims to offer an eco-friendly solution for fruits and vegetables packaging, provide theoretical support and technical guidance for the development of high-performance fruits and vegetables preservation materials, promote innovation in food packaging material science, and support the green packaging transformation under the dual carbon goals.
