Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13636 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

ISO 13636:2012(E)
Introduction
Oriented and non-oriented films and sheets are both made from polyethylene terephthalate (PET).
[2]
ISO 15988:2003 covers only oriented PET films and sheets which have crystalline structure. Non-
oriented PET (APET) films and sheets show quite different properties because of their non-crystalline
structure and require a separate International Standard.
[4]
This International Standard is based on JIS Z 1716:2004, in which, however, only virgin PET resin is
allowed to be used as the raw material.
Additional features of this International Standard are:
a) recycled PET resin can also be used under controlled specified conditions;
b) the structure and classification of film and sheet, such as single, double or triple layer, are specified
in conjunction with applications;
c) applications for food packaging are described in conjunction with food and sanitary laws or
regulations of each country or region.
