Foreword
GB/T 39690 "Plastics - Mixtures of polypropylene (PP) and polyethylene (PE)
recyclate derived from PP and PE used for flexible and rigid consumer
packaging" is divided into two parts:
- Part 1: Designation system and basis for specification;
- Part 2: Preparation of test specimens and determination of properties.
This Part is Part 1 of GB/T 39690.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part, using translation method, is identical to ISO 18263-1:2015 "Plastics
- Mixtures of polypropylene (PP) and polyethylene (PE) recyclate derived from
PP and PE used for flexible and rigid consumer packaging - Part 1: Designation
system and basis for specification".
China’s documents which have a consistent correspondence with the
international documents normatively referenced in this Part are as follows:
- GB/T 1033 (all parts) Plastics - Methods for determining the density of non-
cellular plastics [ISO 1183 (all parts)]
- GB/T 3682.1-2018 Plastics - Determination of the melt mass-flow rate (MFR)
and melt volume-flow rate (MVR) of thermoplastics - Part 1: Standard

Plastics - Mixtures of polypropylene (PP) and
polyethylene (PE) recyclate derived from PP and PE
used for flexible and rigid consumer packaging -
Part 1: Designation system and basis for specification
1 Scope
This Part of GB/T 39690 establishes the designation system and basis for
specification for mixtures of polypropylene (PP) and polyethylene (PE)
recyclate.
It covers mixtures of polypropylene (PP) and polyethylene (PE) recyclate
derived from PP and PE used for flexible and rigid consumer packaging for
moulding and extrusion. Recyclate from packaging used for the transport,
handling, or storage of hazardous goods shall not be used.
It does not apply to mixtures of recyclates and virgin resin.
It does not apply to the mixtures containing special type of PE or PP, for
example, PE-UHMW, TPO, etc.
The types of mixtures of PP and PE recyclate are differentiated from each other
by a classification system based on appropriate levels of the designatory
properties.
a) Composition
b) Melt mass-flow rate
c) Density
d) Colour
It is not intended to imply that materials having the same designation give
necessarily the same performance. This Part of GB/T 39690 does not provide
engineering data, performance data, or data on processing conditions which
may be required to specify a material for a particular application and/or method
of processing. If additional properties are required, they shall be determined in
accordance with the provisions of ISO 18263-2, if applicable.
