Seaweed is a prominent source of polysaccharides with extraction processes properly established, allowing to employ them in several areas. Among all the types of biopolymers obtained from seaweed, furcellaran has gained notoriety in recent years. This is due to its abundance, water solubility and outstanding film-forming abilities. Despite still being little studied, in several works, remarkable advances in terms of improving properties of furcellaran-based films have been described in the literature. However, there are still numerous research opportunities to be explored regarding the improvement of material properties. Therefore, the objective of this review is to highlight the innovative method in preparation, characterization and performance of furcellaran-based films as food packaging. This is the first study in which current results in the area are presented. Initially, it concerns biopolymer chemical and extraction insights. In addition, a comprehensive description of the advances in film properties is outlined (from mechanical to active/intelligent responses). Ultimately, challenges and future prospects are also discussed.

海藻是多糖的重要来源，其提取工艺已正确建立，可在多个领域使用。在从海藻中获得的所有类型的生物聚合物中，近年来，呋塞拉臭名远扬。这是由于其丰富，水溶性和出色的成膜能力。尽管还很少进行研究，但是在几篇著作中，文献中已经描述了在改善基于呋喃纤维素的膜的性能方面的显着进展。然而，关于材料性能的改善，仍有许多研究机会可以探索。因此，本综述的目的是强调在以呋塞拉为基础的食品包装膜的制备，表征和性能方面的创新方法。这是首次提出该地区当前结果的研究。最初，它涉及生物聚合物化学和提取方面的见解。此外，还概述了薄膜性能的进步（从机械响应到主动/智能响应）。最终，还将讨论挑战和未来前景。
