Sojitz Pla-Net and Sun A Kaken Initiate Sales of the World’s First
Pharmaceutical Press-Through-Pack Sheets Manufactured with a Polyvinyl
Chloride Base Formulated with Biomass Polyethylene– Utilizing Biomass-Derived Plastic to Reduce CO2 Emissions by More than 20% –Sojitz Pla-Net Corporation (Head Office: Tokyo; President: Kenichi Ariga) andSun A Kaken Co., Ltd. (Head Office: Tokyo; President: Takeshi Sakurada) have justlaunched Medi Green® as the world’s first pharmaceutical press-through pack (PTP)
sheets which are polyvinyl chloride (PVC) based PTP sheets with Biomass PE
laminating in the inner layer made from non-edible sugarcane blackstrap molasses.
Sugarcane absorbs CO2 from the atmosphere during its growth. The Medi Green®
product is therefore expected to reduce CO2 emissions by more 20%*¹ compared toconventional single layer PTP sheets made from fossil-fuel derived PVC.

Japan’s Ministry of Economy, Trade and Industry has announced its GreenGrowth Strategy for achieving carbon neutrality by 2050, which aims to reduce andreplace fossil-fuel derived plastics with biomass-derived plastics. The
pharmaceutical industry utilizes approximately 14,000 tons*²of PTP sheets fortablet medication annually. One of the industry’s current challenges is to substitutepharmaceutical plastic packaging material with biomass-derived plastics in orderto reduce CO2 emissions.

PTP sheets are most commonly manufactured with PVC and this new Medi
Green® product will be the world’s first PTP sheets to be formulated with a PVC
based sheet with a biomass based PE layer.*² This revolutionary product will
maintain the same high moldability and productivity as conventional PTP sheets
while also being eco-friendly.
South America’s largest chemical manufacturer Braskem S.A. (Head Office:Brazil) is the world’s only manufacturer of biomass PE, which is used in this product.
Sojitz Corporation is a shareholder of Braskem and Sojitz Pla-Net acts as Braskem’s
distributor for the Asian market.
The spread of Medi Green® will promote the transition from fossil-fuel derived
plastics to biomass-derived plastics in the pharmaceutical packaging field which
will contribute to a reduction in CO2 emissions by pharmaceutical companies.
