Edible films and coating materials are commonly used as appropriate packaging materials to extend the shelf life of fresh food. Due to all their properties, edible film and coating materials have been received much attention. They are biodegradable, edible, and good barrier against environmental parameters; thereby, they could carry and deliver food additives protecting food quality. Hydroxypropyl methylcellulose (HPMC), a cellulose derivatives, can act as an excellent film-forming agent for coating food produces. The aim of this study was to provide an overview of the HPMC properties and investigate the effects of various additives on its film-forming properties, such as rheological behavior, water vapor, and gas permeability, as well as mechanical, optical, antioxidant, and antimicrobial properties, with a focus on the recent progress and outputs, which has been recently published. Hydroxypropyl methylcellulose is prone to be commonly used as an advanced film-forming and coating materials for the sake of well miscibility with a wide range of organic and inorganic materials. However, this polymer requires further improvements regarding moisture susceptibility and thermal properties.
可食用薄膜和包衣材料通常用作合适的包装材料，以延长新鲜食品的保质期。由于其所有特性，可食用薄膜和包衣材料受到了广泛关注。它们可生物降解、可食用，并且对环境参数具有良好的阻隔性；因此，它们可以携带和输送保护食品质量的食品添加剂。羟丙基甲基纤维素（HPMC）作为一种纤维素衍生物，可作为食品涂层的优良成膜剂。本研究的目的是概述HPMC的特性，并研究各种添加剂对其成膜性能的影响，如流变行为、水蒸气和气体渗透性，以及机械、光学、抗氧化和抗菌性能，重点关注最近发表的最新进展和成果。羟丙基甲基纤维素因其与多种有机和无机材料具有良好的混溶性，易于用作先进的成膜和包衣材料。然而，这种聚合物在湿度敏感性和热性能方面还需要进一步改进。
