Abstract

The packaging film consists of very thin plastic whose main component is plastic and elastomeric materials. In general, films are used to protect goods from damaging factors. Almost any plastic can be made into film, but this study will only discuss those that are used for commercial packaging. In this research, the types of common polymers used for flexible packaging programs in all industries and the strategy of polymer selection for the production of suitable films are studied, and the role of flexible packaging films in the material supply chain. Food and the role of flexible packaging films in medical equipment and the types of materials used in multi-layer flexible packaging are discussed. Also, thermal properties and polymer seals are studied and application programs are presented for flexible packaging film structures, biaxial and multiaxial films. And finally, a look at the technology of multilayer flexible film structures and a list of polymers used to produce normal buffer layers, bulky layers, interface layers or sealants for layered structures for various applications is described.
