ISO 20299-3:2008

Film for wrapping rubber bales — Part 3: Ethylene-propylene-diene rubber (EPDM), acrylonitrile-butadiene rubber (NBR), hydrogenated nitrile-butadiene rubber (HNBR), acrylic-ethylene rubber (AEM) and acrylic rubber (ACM)

ISO 20299-3:2008 specifies the material and physical property requirements for non-strippable film for wrapping general purpose synthetic rubber bales and intended to keep the bales separate during storage. It concerns wrapping film for the following types of rubber: ethylene-propylene-diene rubber (EPDM); acrylonitrile-butadiene rubber (NBR); hydrogenated nitrile-butadiene rubber (HNBR); acrylic-ethylene rubber (AEM); acrylic rubber (ACM). Certain applications and processing methods require the removal of the film. This part of ISO 20299 does not deal with strippable films.

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 20299-3 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 3, Raw materials (including latex) for use in the rubber industry.
ISO 20299 consists of the following parts, under the general title Film for wrapping rubber bales:
— Part 1: Butadiene rubber (BR) and styrene-butadiene rubber (SBR)
— Part 2: Natural rubber
— Part3:Ethylene-propylene-diene rubber (EPDM), acrylonitrile-butadiene rubber (NBR), hydrogenated
nitrile-butadiene rubber (HNBR), acrylic-ethylene rubber (AEM) and acrylic rubber (ACM)

Introduction
Considerable quantities of synthetic rubber are prepared in crumb form. The crumbs are dried and then pressed
◦
into bales whilst still warm, at approximately 60 C. The bales are then wrapped in a film and packed, often
automatically, into crates.
The wrapping film should be strong enough to withstand the stresses encountered during the wrapping and
packing operations. It should not adhere to the film on the other bales under the combined effects of the heat
from the rubber and the weight of the bales. During storage, the rubber will flow and the film should be able to
withstand the stresses generated. Any failure of the film causes rubber-to-rubber adhesion, which in a 30-bale
crate leads to a “one-tonne bale”.
The prime purpose of the film is to keep the bales separate at all times, so that they may be easily removed from
their pack
