Introduction
The Directive (EU) 2019/904 “on the reduction of the impact of certain plastic products on the
environment” introduces the requirement that plastic caps and lids of single-use plastic beverage
containers and composite beverage packaging up to 3 litres capacity shall remain attached to the
container during the intended use stage.”
This document was developed with the principal objective of:
— Characterizing the attachment of the cap or lid to the container by a minimum resistance to a tensile
force and the ability to remain attached to the container over the products intended use stage.
— Defining the test methods and performance criteria to ensure that the beverage container has met
legal requirements.
— Ensuring that safety aspects of the attachment feature have been considered.
The intended use stage of the product infers that the attachment feature must resist normal handling of
the cap or lid by the consumer to access the contents and, if necessary, reclose the container for
subsequent further servings of the beverage. Intentional forced separation of the cap from the container
will always be possible and is formally excluded from “intended use” as considered in this document.
The development of this document takes into account the necessity not to undermine the requirements
of the Packaging and Packaging Waste Directive (94/62/EC) and its amendments in particular terms of:
— Prevention, limiting the packaging volume and weight to the minimum adequate amount to maintain
the necessary functionality, by avoiding the use of excessive material.
— Recyclability and recycling capability.
In the course of the development of this document it was identified that the attachment of caps and lids
to the container may interfere with established and efficient plastic bottle recycling equipment,
particularly if attached caps or lids hang loose. This aspect is outside of the scope of this document, but it
is recommended that the user takes into consideration best practice guidelines established by the
stakeholders.

1 Scope
This document specifies the requirements and test methods to demonstrate that plastic caps and lids of
single-use beverage containers with a capacity of up to three litres remain attached to the container
during the product’s intended use stage. This document also addresses the need to ensure the necessary
strength, reliability and safety of beverage container closures, including those for carbonated drinks.
This document applies to the strength, reliability and safety impacted by the attachment features and
does not apply to the overall closure system.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

4 Requirements for the attachment feature
4.1 General
The attachment feature of the caps and lids shall have the necessary strength, reliability and safety
required for the intended use stage of the package.
4.2 Strength of the attachment feature
The attachment feature of caps and lids shall have the necessary strength to remain attached to the
beverage container during the intended use stage.
The strength of the attachment feature shall be evaluated in accordance with the test method set out in
5.1 and the criteria specified in 6.1 Table 1.
4.3 Reliability of the attachment feature
The attachment feature of caps and lids shall have the necessary reliability to remain attached to the
beverage container during the intended use stage.
The reliability of the attachment feature shall be evaluated in accordance with the test method set out in
5.2 and the criteria specified in 6.2 Table 2.
4.4 Safety during the intended use stage
The attachment feature of caps and lids shall have the necessary safety characteristics during the
intended use stage.
A risk assessment of the attachment feature shall be carried out to ensure adequate product safety
characteristics for the consumer.
The risk assessment can be integrated into normal product safety assessments.
A method for the risk assessment of the attachment feature is specified in 5.3.
5 Test methods
5.1 Attachment feature – Resistance to a tensile force
5.1.1 General
The test shall verify that the attachment feature of the cap or lid, is able to withstand a given linear tensile
force without being detached from a beverage container.
5.1.2 Equipment required
The tensile testing device shall be capable of applying forces with an accuracy of ± 1 % of the measured
value. The tensile testing device shall be equipped with a clamp, forceps, hook or other suitable gripping
system capable of holding the component firmly without deformation when no force is applied.
5.1.3 Sample size
10 separate samples shall be used for each subtest (subtest 1 and subtest 2), i.e. 20 samples in total.
The tests shall be performed on separate caps or lids, not repeated on the same item.
The samples shall be visually inspected before starting the tests in order to discard any defective samples,
which will need to be replaced with acceptable samples.

5.1.4 Sample preparation
The cap or lid under test shall be applied to the neck finish for which it is designed and in accordance with
the cap or lid manufacturer’s specification.
The temperature of the samples to be tested shall be stabilized for 24 h at (23 ± 2) °C. Testing shall be
carried out at this temperature.
5.1.5 Test method
This test consists of two subtests to assess the resistance of the attachment feature to tensile forces.
1) The first test (subtest 1) shall be in the direction of the neck finish main axis (180°) as shown in
Figure 1.

2) The second test (subtest 2) shall be in a perpendicular direction to the neck finish main axis (90°) as
shown in Figure 2.

In cases where the neck finish forms an integral part of the container, preforms may be used instead of
containers. For neck finishes which are not an integral part of the container separate neck finishes may
be used, held secure in an appropriate fixture for testing.
5.1.6 Subtest 1 in the direction of the neck finish main axis (180°)
The subtest shall be conducted as follows:
a) Place the container with the applied cap or lid into the fixture.
b) Open the cap or lid completely.
c) Attach the opened
