Whatever the tether
While all plastic packaging manufacturers are aware of the same legislation and
brand owner definitions when it comes to tethered closures, how they are interpreting
this brief varies. Packaging communications consultant Emma-Jane Bately examines
the challenges facing producers seeking to design the perfect solution.

F

rom design capabilities to prototypes and
customer feedback,
all tethered closures
have not been created equal.
So, what are the possible variations when everyone has the
same information? Admittedly,
these variations are very small,
particularly from a technical
perspective, yet this is where
the magic happens.
Tiny differences are exactly
what matters when it comes to
a plastic bottle that a consumer holds up to their mouth; is it
comfortable to drink from? Is it
easy to open? Perhaps most importantly for the brands, will the
consumer buy it again?

Sustainability is of course
crucial too, but thankfully this
legislation essentially has sustainability built in as standard,
with the very purpose of its creation being to support the sorting and recycling of single use
plastic packaging. So again, it is
the small details that make the
difference, both in terms of the
volume of raw materials used
and the cost of transportation.
Plastic packaging manufacturer RETAL has long engaged
its design team to focus on creating a tethered closure solution that ticks all the boxes, from
ease of opening to recyclability,
and everything in between.
Thanks to close connections

with its global beverage brand
customers, the company is continually working on new iterations of its tethered closures in
order to create a solution that
meets all the legislative and desirable qualities.
Andzejus Buinovskis, design
engineer at RETAL, explains
how the widely available information from the brands means
that it is the smallest variations
that have the biggest impact.
" Clearly it is imperative that
all the EU SUP Directive rules
of tethered closures, such as
all beverage containers of up
to three litres must have closures that remain attached,
are adhered to, as well as the

definitions published by the
brands themselves. All manufacturers are working to this
same information, and we all
have the goal of designing and
producing a tethered closure
that meets all the criteria and
is pleasant to use. The evolving nature of the information
makes for a design challenge
as well as a design opportunity; I am working on the tiniest
changes, but they are crucial.
There is a great challenge in
knowing that you can only
work with certain aspects and
that it is your imagination and
skill that makes the difference. "
These potentially crucial
tiny changes come from the
