When the blister sheet
changes, the future changes

ClearE-Sheet® is an innovative pharmaceutical packaging sheet that delivers both environmental responsibility and uncompromising medical safety.
It preserves the trusted functionality of conventional blister sheets while reducing plastic waste during manufacturing by over 70%.
The sheet’s transparent edges clearly showcase its eco-friendly design. Beyond the sheet itself, we envision a brighter future for people and society.
CKD’s technology provides “sustainable safety feeling”, extending care to the next generation.

For 70 years, medicine packaging sheets have remained largely unchanged.
The packaging has been slightly refreshed for the future.

The blister sheet — the familiar packaging that individually encloses each tablet and capsule.
For decades, CKD has focused on safely delivering medicines through the development of machinery that manufactures blister sheets.
While the basic form has remained virtually unchanged for 70 years continuously supporting global health.
However, plastic scrap is inevitably generated during the manufacturing process.
— We realized this had to change.
That determination led to the birth of ClearE-Sheet®.

Packaging medicine.
A New Form of Visible Kindness

ClearE-Sheet® is an eco-friendly blister sheet made using CKD’s proprietary EcoScrap Technology.
Its distinctive transparent edge makes environmental consideration clearly visible within the familiar sheet design.
When patients or pharmacy staff hold it, they can immediately recognize it as eco-friendly medication packaging.
It is packaging designed with kindness for both people and the planet.

Packaging performance remains unchanged.
Made with CKD’s proprietary EcoScrap Technology, it is kinder to the planet.

Leveraging CKD’s proprietary sheet transport and plastic waste recovery technologies, ClearE-Sheet® eliminates edge plastic waste during manufacturing — reducing plastic waste by more than 70%.
When held in the hand，Its transparent edges let light pass through, reflecting its environmental commitment. The new blister sheet maintains the same proven reliability in protecting medicines.

  • Plastic waste generated during manufacturing

    Over

    70%

    reduction

  • Plastic usage

    Over

    7%

    reduction

When small blister sheets come together,
they make a big difference.

If ClearE-Sheet® were adopted nationwide…

  • Annual plastic waste generation

  • Annual CO₂ emissions from plastic waste

To put that into perspective......

  • Equivalent to the plastic waste of
    approximately 30 million
    PET bottles
    *1

  • Equivalent to the annual plastic waste
    emissions of approximately
    18,500 people *2

  • Equivalent to the CO₂ absorption
    capacity
    of approximately
    465,000 cedar trees
    *3

  • If the reduced plastic were stretched into 1-cm-wide strips, it could wrap around the Earth approximately 10.1times *4

The visual difference may be so small.
But that “small difference” can brighten the future.

Visible kindness
will become the new "standard."

Medicine is meant to pack a safety feeling for someone.
And if its packaging can also be kind to the planet,
it can make every day a little brighter for all of us.
ClearE-Sheet® aims to wrap both trust in healthcare and
care for the environment, creating a new standard of visible kindness.
