26 Jul 2023 --- Packamama and international cooperation The Wine Society are collaborating to spread eco-flat wine bottles made of recycled PET (rPET) throughout the society members’ product ranges to reduce carbon emissions. The flat-pack bottles are lighter than glass bottles, weighing 63 g compared to an average of 460 g for glass bottles, resulting in a lower-carbon footprint and offering consumers greater convenience and portability through their space-saving design.
