ISO/DIS 13106
Introduction
The packaging of liquid foods has traditionally used glass or metal containers.  Plastics packaging, especially
using blow-molded containers has proven to be an effective substitute offering many advantages including
alternative manufacturing options, lower weights, design flexibility, and packaging aesthetics.
In addition to these benefits, polypropylene blow-molded containers offer the advantages of being able to be
hot-filled and, in some cases autoclaved for sterilization of the contents. Polypropylene containers can also
be manufactured as co-extruded structures allowing the inclusion of barrier layers to improve shelf-life or to
incorporate layers composed of recycled polypropylene.
When properly specified and formulated, polypropylene is compliant to food contact requirements e.g., FDA,
is highly resistant to many chemicals, exhibits very high stress crack resistance, and has the necessary
balance of mechanical properties to meet the requirements for handling, storage, and transportation

DRAFT INTERNATIONAL STANDARD ISO/DIS 13106

Plastics — Blow-moulded polypropylene containers for
packaging of liquid foodstuffs
1 Scope
This International standard prescribes the requirements for polypropylene resins intended to be used in the
manufacture of blow-molded containers for use in liquid-food packaging. The standard also provides general
guidance and recommendations regarding tolerances and sampling and information addressing environmental
aspects and proper recovery and recycling practices.
Although applicable, this standard does not address other applications for blow-molded polypropylene
containers. These must often meet specific requirements which will need to be addressed for these
applications.
NOTE: It is not to be implied that polypropylene is the only polymer suitable for these applications as many
other polymers i.e. PP-HD, PET, etc. are also suitable.
