An increased interest for hygiene in everyday life as well as in food, feed and medical issues lead to a strong interest in films and blends to prevent the growth and accumulation of harmful bacteria. A growing trend is to use synthetic and natural antimicrobial polymers, to provide non-migratory and non-depleting protection agents for application in films, coatings and packaging. In food packaging, antimicrobial effects add up to the barrier properties of the materials, to increase the shelf life and product quality. Chitosan is a natural bioactive polysaccharide with intrinsic antimicrobial activity and, due to its exceptional physicochemical properties imparted by the polysaccharide backbone, has been recognized as a natural alternative to chemically synthesized antimicrobial polymers. This, associated with the increasing preference for biofunctional materials from renewable resources, resulted in a significant interest on the potential for application of chitosan in packaging materials. In this review we describe the latest developments of chitosan films and blends as packaging material.
日常生活、食品、饲料和医疗领域对卫生的日益关注，促使人们对能够防止有害细菌生长和积累的薄膜和混合物产生了浓厚的兴趣。一种日益增长的趋势是使用合成和天然抗菌聚合物，为薄膜、涂料和包装提供非迁移性和非消耗性的保护剂。在食品包装中，抗菌效果与材料的阻隔性能相结合，可延长保质期并提高产品质量。壳聚糖是一种具有内在抗菌活性的天然生物活性多糖，由于其多糖主链赋予的特殊物理化学性质，已被认为是化学合成抗菌聚合物的天然替代品。这一点，再加上人们对可再生资源的生物功能材料的日益偏好，使得壳聚糖在包装材料中的应用潜力受到了极大关注。在本文综述中，我们描述了壳聚糖薄膜和混合物作为包装材料的最新进展。
