INTERNATIONAL STANDARD ISO 13106:2014(E)
Plastics — Blow-moulded polypropylene containers for
packaging of liquid foodstuffs
WARNING — This International Standard does not purport to address all of the safety concerns,
if any, associated with its use. It is the responsibility of the user of this International Standard to
establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use.
1 Scope
This International Standard provides the requirements of polypropylene resins intended for use in blow-
moulded, round containers with capacities up to, and including two litres intended for the packaging
of liquids for human consumption. This International Standard also provides tolerances on mass,
dimensions, methods of sampling, testing, and performance requirements.
NOTE It is not to be implied that polypropylene resins are the only polymers suitable for these applications,
as many other polymers, including PE-HD, PET, etc. are also suitable.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following definitions of terms apply.

(H) for containers produced using ISBM technology is the perpendicular distance from highest point of the neck
face to bottom plane of the support ledge. The brimful capacity can also be measured using special volume testing
equipment (Annex B). For bottles and lipped containers, nominal capacity is approximately 90 % of the brimful
capacity.

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.
