New Thin Film Deposition Technology for PET bottles Recognized For Advanced
Packaging Technology as a WORLDSTAR WINNER and a Diamond Finalist- New eco-friendly PET bottle technology prevents degradation of the contents while reducing weight TOKYO, Thursday February 18, 2021 - Kirin Holdings Company, Limited (Kirin Holdings), the Packaging
Innovation Laboratory (“Packaging Innovation”) has developed a new thin film deposition technology for PET
bottles using a hot wire CVD technique for an environmentally-friendly package.
In recognition of the results of this development, on January 7, 2021 Kirin Holdings was recognized as one of theWORLDSTAR WINNERS in the Beverages category of the WORLDSTAR Packaging Awards 2021 organized by
the World Packaging Organization (WPO). The technology was also selected as a Diamond Finalist presented at theDow Packaging Innovation Awards 2020, organized by Dow Chemical Company in the United States on
November 11, 2020.
Kirin Holdings’ Institute for Package Innovation specializes in the development of packaging containers and has
led the industry in the development of a range of environmentally-friendly containers, including lighter returnablebeer bottles, smaller aluminum can lids and the lightest 2-liter PET bottle in Japan*1.
*1: As of December 2020

This New Thin Film Deposition Technology for PET Bottles, (the hot wire CVD technique) also won the44th Kinoshita Award in September 2020. This technology is expected to contribute to resource conservation
by forming a colorless, transparent and recyclable gas barrier film on PET bottles, which prevents oxidationand degradation of the content liquid while reducing weight.
The Kirin Group is committed to promoting global CSV*2 by creating value across our world of Food & Beverages toPharmaceuticals. Kirin Group Environmental Vision 2050, a new vision statement on stronger social and corporate resilienceestablished in February 2020 as part of the broader CSV environmental initiative, calls for sustainable recycling ofcontainers and packaging at the macro level. We will continue to promote the development of sustainable containers andpackaging by using these and other technologies to save resources, while taking into account the convenience of ourcustomers. In this way, we will try to solve social issues.

 Research title:
New thin film deposition technology for PET bottles by hot wire CVD system
 Research overview：
In recent years, environmental concerns have led to the development oftechnologies to make PET bottles thinner and lighter. However, because
thin PET bottles are easily permeable to oxygen, carbon dioxide andwater vapor, there is a risk of oxidation and deterioration of thebeverage contents, which limits weight reduction. Various gas-barrier
technologies have been developed to reduce the permeation of oxygenand other gases, but these have had problems such as reducing thetransparency of the bottle, limiting the range of drinks that can befilled, and making recycling difficult.

●What is a new thin film deposition using a hotwire CVD system?
A PET bottle is filled with gas, the raw material for thefilm, and a ceramic rod (hot wire) is used to raise thetemperature so that the decomposed gas is deposited on
the inner surface of the PET bottle. The decomposedgas forms a film and prevents permeation.

 How does it work?
This technology uses special ceramic rods to form a thin film on
the inner surface of the bottle that prevents the permeation of oxygen and other substances (see the abovefigure). By devising the type of film material and the conditions under which the film is formed, it has
become possible to fill the bottles with a variety of clear and colorless beverages. In addition the bottles arerecyclable in accordance with the Voluntary Design Guidelines for Designated PET Bottles issued by thePET Bottle Recycling Promotion Council*3, thus reducing the environmental impact of the bottles.

With these features, this technology is expected to help reduce the weight of PET bottles even more than
before, regardless of the liquid content.

The WORLDSTAR Packaging Awards 2021 is a contest run by the World Packaging Organization (WPO)with the aim of promoting the world's best packaging and its technology.
Winners of the Japan Packaging Contest, organized by the Japan Packaging Institute, are eligible to enter theWORLDSTAR Packaging Awards, where they compete against entries from around the world to win prizes.
In the WORLDSTAR Packaging Awards 2021, 345 entries were received from around the world (the most,26 came from Japan), and as a result of a rigorous selection process, the WORLDSTAR WINNER was given
to Kirin Holdings’ New thin film deposition technology for PET bottles using hot wire CVD equipment.
What the “Dow Packaging Innovation Awards” Is

The Dow Packaging Innovation Awards are sponsored by The Dow Chemical Company, the world's leadingchemical company. The Dow Packaging Innovation Awards, formerly known as the DuPont Awards, are
now in their 32nd year and have a global history.
In this year's Dow Packaging Innovation Awards, "New thin film deposition technology for PET bottles
using hot wire CVD system" was selected as one of the four finalists for the Diamond Award out of 175
companies from around the world.
