รายละเอียดเอกสาร

This standard provides a classification system for tabulating the properties of unfilled, single-layer plastic films. NOTE 1: The classification system serves many of the needs of industries using plastic films. The standard is subject to revision as the need requires; therefore, the latest revision should always be used. NOTE 2: Film is defined in Terminology D883 as an optional term for sheeting having a nominal thickness no greater than 0.25 mm [0.010 in.]. The classification system and subsequent line call-out (specification) is intended to be a means of identifying plastic films used for applications including industrial, packaging, construction, and agriculture. It is not intended for the selection of materials to be used in films. This selection should be made by those having expertise in the plastics field after careful consideration of the end-use requirements, the environment to which the films will be exposed, the fabrication process to be employed, the inherent properties of the material not covered in this document, and the economic factors.
