paper hot cup

Q - What makes this cup unique?In a conventional paper hot cup, the inner surface is lined with a petroleum-based plastic (polyethylene) to prevent leaking. Our new cup is lined with a bio-plastic made from corn. That makes this the only paper hot cup made from fully renewable materialsa small but important step toward a more sustainable future. Q - What prevents the corn-based lining from dissolving in contact with hot coffee?The lining in this cup is based on a resin made from a new material, modified polylactic acid (PLA), that is unaffected by the temperature of the beverage. But, it can be consumed by microbes over time and break down into the components nature started withwater, carbon dioxide and organic matter.
