Introduction
The demand for more advanced traceability and reduction in both distribution costs and logistics materials
has recently increased in supply chains worldwide, and the use of radio-frequency identification (RFID) in
supply chains is regarded as an ideal solution. In actual logistics and material handling, many materials
and items are lost or go missing due to the lack of an efficient returnable transport item (RTI) management
system, imposing extra costs on companies and enterprises due to additional ordering.
Today, there is strong demand for efficient plastic RTI management especially in the automobile industry
where many parts and components are designed exclusively for automotive use. Plastic RTIs are used
to store and transport a variety of stored items. In this technical report, the measurement results of
evaluations of RF tag on RTIs for the transport of automotive parts are presented. The results show the
changes in durability and communication performance of RF tags attached to plastic RTIs when exposed
to various environmental stresses. The results provide insight into the durability of RF tags in various RTI
environments and will be useful in many situations where RF tags are attached to plastic RTIs.

4 Characteristics of RFID for plastic RTIs
4.1 General
When RF tags are attached to inexpensive plastic RTIs used for various purposes and RFID is used for
operation management, the following points should be considered.
— First, RF tags attached to inexpensive plastic RTIs also need to be low cost, but inexpensive RF tags
marketed for general use are generally manufactured for use in the distribution industry, so it is unclear
whether they are reliable enough for long-term use when attached to plastic RTIs. For example, price tag
labels are attached to RF tags used in the distribution industry, but because they are used in one-way
disposable applications, the conditions for attaching them are very different from plastic RTIs for returnable
applications.
— Also, since plastic RTIs are generally transported using conveyor belts and forklifts, RF tags
are subject to various forms of physical stress, such as vibration, impact, rough handling of plastic RTIs
by operators, and shrinkage of plastic material due to temperature changes. In addition, they are also
exposed to chemical stresses from chemicals and plastic RTI washing. However, few evaluations have been
performed to assess the extent to which commercially available RF tags attached to RTIs are affected by
stresses attached to plastic RTIs during transport and washing.
— As used RF tags are generally incinerated or dissolved, the safety of written data is not considered.
In addition, for example, as the data of RF tags used in the automobile industry is common data based on ISO
standards, there is no problem even if the data is leaked. However, if security information other than ISO
standards is written, it is desirable to destroy used RF tags and IC chips so that the information cannot be
read, and to incinerate or dissolve them.
4.2 Unit reliability evaluations
4.2.1 Overview of test methods
RF tags attached to plastic RTIs are subject to physical stresses such as vibrations, shocks, rough handling
of plastic RTIs, temperature changes, and chemical stresses due to chemicals and washing during parts
transport.
Therefore, 7 kinds of commercially available RF tags were attached to the materials used for plastic RTI, and
14 kinds of tests (see Table 1 " Summary of main results ") were conducted under the assumed conditions to
evaluate the physical and the performance changes of the RF tags after the tests.
4.2.2 Plastic RTI types and materials
Plastic RTI includes special types such as containers, pallets, folding containers, and dunnages, but the
materials themselves are broadly divided into PE and PP materials. (See Annex A Examples of Plastic RTIs
for Supply Chain)
The majority of plastic RTIs used in various applications are made of PP, but some are made of PE. PE has
better shock resistance at low temperatures than PP and is used in low-temperature environments such as
the fishing industry and food industry. However, because of its low cost, light weight, rigidity, moldability
and heat resistance, PP is the plastic material of choice except for special applications such as refrigerated
warehouses.
— PP consists of homopolymers with high rigidity and high heat-resistance, random copolymers with high
transparency and high flexibility, and block copolymers with high shock-resistance, and is mainly used
for plastic returnable containers.
— PE is available in low-density, medium-density and high-density types. The high-density type is mainly
used for plastic returnable containers.
Plastic RTIs include antistatic RTIs used for storing and transporting electronic components sensitive to
static electricity; however, they are generally used less frequently and have fewer applications than general-
purpose plastic RTIs, as such, they were not evaluated here. Further, the influence of the dielectric constant
on the reading of the RF tag when the RF tag is attached to the plastic is not as serious as when the RF tag is
attached to the metal, hence, it is not an issue. Since plastic RTIs can be used for many years, we evaluated
how RF tags attached to such materials aged.
4.2.3 Main evaluation results
Table 1 shows the evaluation results of the general-purpose RF tags attached to plastic RTIs and plastic
boards. For more information on evaluation RF tag samples, evaluation methods, and results, see Annex B

Seven types of general-purpose RF tags were used for evaluations and assigned numbers starting with A, B,
C, D, E, FA or FB. See Table B.2 for other RF tag specifications such as substrate materials and applied surface
adhesives.
The evaluations in Annex B were performed by attaching general-purpose RF tags to various types of boards.
Before performing evaluations, each RF tag was encoded with a sample number, which was printed on the
surface substrate of the RF tag.
The printer ribbons used for printing were selected from among three types (a, b, c) as shown in Table B.2
based on their suitability with each label, with test printing being performed beforehand to check print
quality.

— One RF tag of NO. B suffered a loss in functionality or loss their ability to communicate (due to moisture
permeated to the IC chip), while the remaining 41 RF tags retained their ability to communicate (total of
2,4 % of RF tags suffered a loss in functionality).
— All paper on the printed surfaces of the tags became permeated.

Introduction
The demand for more advanced traceability and reduction in both distribution costs and logistics materials
has recently increased in supply chains worldwide, and the use of radio-frequency identification (RFID) in
supply chains is regarded as an ideal solution. In actual logistics and material handling, many materials and
items are lost or go missing due to the lack of an efficient returnable transport item (RTI) management system,
imposing extra costs on companies and enterprises due to additional ordering.
Today, there is strong demand for efficient plastic RTI management especially in the automobile industry
where many parts and components are designed exclusively for automotive use. Plastic RTIs are used to store
and transport a variety of stored items. In this TRtechnical report, the measurement results of evaluations of
RF tag on RTIs for the transport of automotive parts are presented. The results show the changes in durability
and communication performance of RF tags attached to plastic RTIs when exposed to various environmental
stresses. The results provide insight into the durability of RF tags in various RTI environments and will be
useful in many situations where RF tags are attached to plastic RTIs.

4 Characteristics of RFID for Plasticplastic RTIs
4.1 General
When RF tags are attached to inexpensive plastic RTIs used for various purposes and RFID is used for
operation management, whatthe following points should be considered?.
— First, RF tags attached to inexpensive plastic RTIs also need to be low cost, but inexpensive RF
tags marketed for general use are generally manufactured for use in the distribution industry, so it is unclear
whether they are reliable enough for long-term use when attached to plastic RTIs. For example, price tag labels
are attached to RF tags used in the distribution industry, but because they are used in one-way disposable
applications, the conditions for attaching them are very different from plastic RTIs for returnable applications.
— Also, since plastic RTIs are generally transported using conveyor belts and forklifts, RF tags are
subject to various forms of physical stress, such as vibration, impact, rough handling of plastic RTIs by
operators, and shrinkage of plastic material durdue to temperature changes. In addition, they are also exposed
to chemical stresses from chemicals and plastic RTI washing. However, few evaluations have been performed
to assess the extent to which commercially available RF tags attached to RTIs are affected by stresses attached
to plastic RTIs during transport and washing.
— As used RF tags are generally incinerated or dissolved, the safety of written data is not
considered. In addition, for example, as the data of RF tags used in the automobile industry is common data
based on ISO standards, there is no problem even if the data is leaked. However, if security information other
than ISO standards is written, it is desirable to destroy used RF tags and IC chips so that the information cannot
be read, and to incinerate or dissolve them.
4.2 Unit reliability evaluations
4.2.1 Overview of test methods
RF tags attached to plastic RTIs are subject to physical stresses such as vibrations, shocks, rough handling of
plastic RTIs, temperature changes, and chemical stresses due to chemicals and washing during parts
transport.
Therefore, 7 kinds of commercially available RF tags were attached to the materials used for plastic RTI, and
14 kinds of tests (see Table 1 "Table 1 " Summary of main results ") were conducted under the assumed
conditions to evaluate the physical and the performance changes of the RF tags after the tests.
4.2.2 Plastic RTI types and materials
Plastic RTI includes special types such as containers, pallets, folding containers, and dunnages, but the
materials themselves are broadly divided into PE and PP materials. （(See Annex A 0 Examples of Plastic RTIs
for Supply Chain）)
The majority of plastic RTIs used in various applications are made of PP, but some are made of PE. PE has
better shock resistance at low temperatures than PP and is used in low-temperature environments such as
the fishing industry and food industry. However, because of its low cost, light weight, rigidity, moldability and
heat resistance, PP is the plastic material of choice except for special applications such as refrigerated
warehouses.
— ・PP consists of homopolymers with high rigidity and high heat-resistance, random copolymers with high
transparency and high flexibility, and block copolymers with high shock-resistance, and is mainly used for
plastic returnable containers.
— ・PE is available in low-density, medium-density and high-density types. The high-density type is mainly
used for plastic returnable containers.
Plastic RTIs include antistatic RTIs used for storing and transporting electronic components sensitive to static
electricity, but; however, they are generally used less frequently and have fewer applications than general-
purpose plastic RTIs. So, as such, they weren’twere not evaluated here. Further, there is no problem because
the influence of the dielectric constant on the reading of the RF tag when the RF tag is attached to the plastic
is not as serious as when the RF tag is attached to the metal., hence, it is not an issue. Since plastic RTIs can be
used for many years, we evaluated how RF tags attached to such materials aged.
4.2.3 Main evaluation results
Table 1Table 1 shows the evaluation results of the general-purpose RF tags attached to plastic RTIs and plastic
boards. For more information on evaluation RF tag samples, evaluation methods, and results, see Annex B and

B.2 RF tags used for evaluation
Seven types of general-purpose RF tags were used for evaluations and assigned numbers starting with A, B, C,
D, E, FA or FB. See Table B.2Table B.2 for other RF tag specifications such as substrate materials and applied
surface adhesives.
The evaluations in Annex B0 were performed by attaching general-purpose RF tags to various types of boards.
Before performing evaluations, each RF tag was encoded with a sample number, which was printed on the
surface substrate of the RF tag.
The printer ribbons used for printing were selected from among three types (a, b, c) as shown in Table
B.2Table B.2 based on their suitability with each label, with test printing being performed beforehand to check
print quality.

B.10.8  Summary of water immersion tests
— • One RF tag of NO. B suffered a loss in functionality or loss their ability to communicate (due to moisture
permeated to the IC chip), while the remaining 41 RF tags retained their ability to communicate (total of
2.,4 % of RF tags suffered a loss in functionality).
— • All paper on the printed surfaces of the tags became permeated.
— • The printing surface came off or characters disappeared with even the slightest friction because the
printing surface permeated.
