We love to see a new paper-style bottle hitting our shelves (at least the prototype shelf). But they always come up against the same two problems: what makes the paper impervious to water, and how is the bottle closed?
Blue Ocean Closures (BOC) has the answer to at least one of these problems with its vacuum-formed moulded fibre screw cap. The material is recyclable and biodegrades in the ocean, but to make it to market quickly, the company has fallen back on a PHA (plastic) liner. As soon as this is improved, a potentially game-changing alternative to plastic caps could be at hand.
