The BS EN 16063-2011 standard specifies the terminology of plastic film for rigid plastic containers. The standard aims to unify and standardize the terminology in the Encasement industry relating to the surface film of rigid plastic containers to ensure conformity during production and communication. The standard describes in detail the definition, classification and scope of application of different types of plastic films, covering the Appearance, Function and Technical requirements of coatings. These terms help interested parties to accurately communicate and understand the characteristics of films in design, production, quality control and market communication. Technological progress and international collaboration in the plastic container Encasement industry have been promoted through standardization of terminology.
