Pulpex founding partner companies include Diageo, Unilever and PepsiCo, with a stated goal of moving products away from plastic packaging. Johnnie Walker Scotch whisky will be sold in food-grade paper bottles starting in 2021, free of thermoplastic polymer resin known as PET, and will be totally recyclable. TetraPaks, by contrast are manufactured with thin layers of polyethylene wedged between the paper and aluminum, which makes these packages difficult to recycle. Pulpex products aim to avoid that. As we all know, paper and liquids don’t always play well together, so getting this technology to work at scale will go a long way to reducing the amount of plastic floating around. Why not just stick with glass? It's heavier than cardboard and so carries a larger carbon footprint.
In addition to Johnnie Walker, look for non alcoholic beverages from PepsiCo and personal and household care items from Unilever to appear sheathed in paper in the near future. And not a moment too soon: Diageo, the parent company of Johnnie Walker, uses plastic in 5% of all its packaging, but PepsiCo and Unilever rank among the world’s top plastic producers. Let's all pour one out in the hopes that this is a success.
