Various packaging technologies have been developed to meet continuously increasing consumer demand for comfortable and safe use, convenience of use, and fresh quality of packaged products. Porous and breathable films provide various advantages such as the minimization of anaerobiosis originating from the accumulation of CO₂ in packaging and the automatic release of steam in a microwave system. Non-porous breathable films are among the alternative candidates for packaging applications and they can respond to desired and undesired temperature fluctuations by reversibly changing the gas permeability depending on the temperature change. They can also prevent problems related to packaging integrity such as the intrusion of insects and microorganisms through perforations, undesired permeation of moisture, and loss of flavor in agricultural products and food. This review mainly addresses porous and non-porous breathable films that are responsive to stimuli like temperature changes. Further, the importance and possible packaging application areas of non-porous breathable films with temperature-dependent gas permeabilities are briefly identified.

已经开发出各种包装技术来满足消费者对于舒适和安全使用，使用便利以及包装产品的新鲜质量的不断增长的需求。多孔且透气的薄膜具有多种优势，例如可最大程度减少源自CO ₂积累的厌氧菌病包装和微波系统中蒸汽的自动释放。无孔透气膜是用于包装应用的替代候选物，它们可以通过根据温度变化可逆地改变气体渗透率来响应期望的和不期望的温度波动。它们还可以防止与包装完整性有关的问题，例如通过穿孔侵入昆虫和微生物，不希望的水分渗透以及农产品和食品的风味损失。这篇综述主要针对对温度变化等刺激有反应的多孔和无孔透气膜。此外，简要确定了具有随温度变化的气体渗透性的无孔透气膜的重要性和可能的​​包装应用领域。
